Dear ProjectSafety Supporter,
April 6, 2004
RE: Support for establishing a test network in the Tampa Bay, FL region
for the beta deployment of the standards, protocols and
recommended engineering practices for an Integrated 4.9 GHz Public
Safety I 5.9 GHz WAVE radio system to form a Community Network
Infrastructure.
This CD includes supporting documents. The White Paper and support letter from the
National Public Safety Telecommunications Council (NPSTC) provides an overview and
confirmation that this proposal has undergone rigorous technical and operational
overview. Your actions will decide if this technology test bed will be deployed in
California or Tampa Bay, along with a new 20 billion dollar industry cluster that will
attracted hundreds of companies and thousands of high paying jobs. The project
team has already been established and resides at the Young-Rainey Star Center in
Largo, FL within Congressman Bill Young's (Chairman of House Appropriations) district.
This opportunity needs your support so that we can be the test bed for the nation and
obtain Federal funding. This is critical for homeland security and other services. This
program has major national and international implications.
Many of the best engineers and companies in the world offering wireless and sensor
technologies reside in the Tampa Bay area. The State of Florida needs to be the global
center for this new industry. We have a plan including local regional and national
support. We need to act now or we will loose this opportunity to San Diego or other
community. This program has the potential to generate more jobs and spinoffs
than the Scripps Institute in Palm Beach County, while costing Florida virtually
nothing. In fact, it will lower government costs for delivering critical services to Florida
residents, allowing Florida to either expand government services or lower taxes.
Please call and fax Harry Glenn of Congressman Bill Young's staff to provide your
support for this program at 202-225-5961 or fax 202-225-9764. An example support
letter for you to send to Congressman Bill Young is on the CD.
Sincerely,

Community Network Infrastructure
Ovenriew:
The community network infrastructure uses Wi-Fi (IEEE 802.11) open standard
hardware. This is the same hardware that one can purchase for $40-50 today to access
Wi-Fi hotspots at McDonalds and other service providers. This hardware will be
enhanced with Mobile Ad Hoc Networking technology to enable each user / device to
relay data for each other, extending the effective range and performance of the hardware.
The primary focus of the network is to provide data communications for Public Safety
purposes, with non-Public Safety applications given secondary priority on the network.
This would allow the government to minimize investment in the network, by utilizing
private individual's hardware to extend the network. The bargain that citizens make for
joining the network is that Public Safety is given priority access, in exchange the other
99.99% of the time that Public Safety is not using the network, they may enjoy Internet
access.
Why this is the time for implementation:
Per the White Paper, the proposed system will leverage standards for Intelligent
Transportation Systems (ITS) communications systems that will be installed in all new
vehicles manufactured in the world. The Federal Highway Administration expects
millions traffic lights will be equipped with this hardware. The ITS hardware standard is
moving through the IEEE 802.11 standards organization and will become part of Wi-Fi.
Also the National Public Safety Telecommunications Council (NPSTC), which represents
all governmental Public Safety user groups, supports (see NPSTC support letter) the use
of IEEE 802.11j hardware in the recently allocated 4.9 GHz spectrum for Public Safety
organizations.
As Wi-Fi hardware will soon be able to operate in all of the frequencies between 4.9 and
5.9 GHz, the opportunity to deploy such a system is at our doorstep. As Public Safety
organizations and automobile manufacturers throughout the world will adopt these
standards I systems through Project MESA and ISO (International Standards
Organization)
Benefits of eNI:
Considering that a one Gigabit connection to the Internet costs less than $10,000 per
month today (Vendor: Cogent Communications), by using existing traffic signal fiber
networks to backhaul and aggregate Internet traffic into such connections will lower costs
to government organizations by sharing the infrastructure. For example a Gigabit can
provide all the bandwidth needed by all schools, libraries, police stations, fire stations,
and other local, state and federal government entities in Central Florida. According to
research by Telegeography, global aggregate Internet bandwidth in 2002 was less than
1,500 Gigabits.
By enlisting citizens to extend the network from the "traffic signal hotspots", we extend
the network at no cost to the government users. Consider that existing Wi-Fi hardware
delivers bandwidth up to 108 Megabits and with the proposed enhancements within IEEE
802.11 standards organizations, this will increase to over 200 Megabits in the future.
This provides significant bandwidth to first responder Public Safety organizations.
Potential sample application benefits within various Government user groups:
Dept. of Education: Students can access Computer Based Training systems at their local
schools to deliver on government "No Child Left Behind" initiatives. Students can
receive programs not available at their local school - If University of Phoenix online can
do it, why can't a high school do it? Local Community Colleges can deliver education
online over the CN!.
Dept. of Justice: Local on-scene Public Safety (Police, Fire, etc.) can deliver
information directly to FBI, ATF, and other federal agencies. Local agencies can access
federal resources - databases.
Dept. of Homeland Security: Ability to deploy remote sensors to detect CNBC
(Conventional, Nuclear, Biological and Chemical) threats throughout the transportation
infrastructure. DHS as on-scene commander for Terrorism incidents can coordinate
communications with supporting local Public Safety Agencies. SAFECOM within DHS
is tasked with establishing Standards and Interoperability requirements for Public Safety
communications. Everyone understands now that Fire needs to communicate with
Police, Sheriff, EMS, Highway Patrol, Coast Guard, etc. in Incident Management
situations. Standards and Interoperability are key, Tom Coty, Deputy Director for
Standards and Interoperability supports NPSTC's efforts in this area. Tom has also stated
that no funding has been allocated for data communications interoperability initiatives
within SAFECOM.
Dept. of Defense: Because the proposed system is a blueprint for the world, it is
expected through Project MESA and ISO, our standard will become a global standard.
This means support activities worldwide can use this communications system.
Dept. of Transportation: 5.9 ITS communications systems are critical to deliver DOT's
goal of reducing traffic fatalities by 50% or 20,000 annually over the next ten years.
Traffic fatalities and injuries have more impact annually than all the terrorist actions
against the USA, worldwide have had.
President Bush & Candidate Kerry: Both have called for affordable broadband. The
CNI delivers, with the added benefit of prioritizing communication assets to first address
Public Safety. In exchange for citizens to deploy the hardware needed by our Public
Safety agencies, they get affordable Internet access. Broadband Internet access over the
eNI could be as low as $10/ year.

RE: Support for establishing a test network in the Tampa Bay, FL region for the
beta deployment of the standards, protocols and recommended
engineering practices for an Integrated 4.9 GHz Public Safety I 5.9 GHz
WAVE radio system to form a Community Network Infrastructure.
Dear Congressman Young:
On behalf of I wish to convey our support for the above
entitled project that is proposed to be conducted in the Tampa Bay region for the benefit
of the national and global public safety community, global Intelligent Transportation
Systems (ITS) community and to help address Homeland Security issues confronting
the USA and world. We urge you to earmark funding for this project as soon as
possible to meet the needs of our national public safety community.
Over the last two years, Mohan Pundari of St. Petersburg, FL has presented to NPSTC
(National Public Safety Telecommunications Council), DHS (Department of Homeland
Security) SAFECOM, and the 5.9 GHz DSRCIWAVE program office within the FHWA
(Federal Highway Administration) an integrated vision (White Paper) for 4.9 GHz I 5.9
GHz Public Safety Communications. Pinellas County Public Safety agencies have
agreed to provide the "hands on practical experience" vital to providing the solutions
and necessary applications for the global public safety community that will lead to
effective global deployment. We understand our responsibilities to help in the
development of more effective public safety communications systems.
Like NPSTC and other supporters of this initiative, we also believe that the Pinellas
Team is uniquely qualified to support the establishment of the standards, protocols and
recommended engineering practices for 4.9 GHz I 5.9 GHz communication systems.
We agree with NPSTC that the Pinellas Team has addressed many of the issues
surrounding the development of interoperable 4.9 GHz I 5.9 GHz communication
systems that can meet the needs of various public safety and governmental agencies.
Congressman Bill Young, we support and encourage your efforts to address this critical
need for the public safety and government community, through funding of this initiative
at the Young-Rainey STAR Center. The economic development from this emerging
$20 Billion market and over 20,000 jobs it will create in the Tampa Bay region is
simply a byproduct of your efforts to improve public safety for all citizens of the world.

Public Safety Communications Networks
Eu'cuti\ l' SLlmmar~
The Need
Public Safety organizations do not have an
interoperable communications platform
that can provide localized, broadband, ad
hoc peer-to-peer or multicast connections.
The recent allocation of 50 MHz of
spectrum from 4.940 to 4.990 GHz
provides the spectrum from which such
services can be deployed.
Public Safety Vehicle data network needs
are typically serviced through commercial
WAN links such as CDPD or over low
bandwidth Public Safety data networks
today. These data links do not support
interagency peer-to-peer or small
group/team multicast services and have
high network latency, along with very
limited capacity. Voice services are
typically delivered over Public Safety
analog radio networks. When multiple
agencies (Fire, Police, EMS, Coast Guard,
etc.) respond to incidents, an
interoperable communications platform is
not available for local communications
and interagency data dissemination.
The approach by some vendors is to
"sell" budget constrained public safety
agencies on $100,000+ mobile switches to
interconnect the current hardware from all
the agencies through the $100,000+
mobile switch. This is a poor way to deal
with C4 (Command, Control,
Communications, and Computing) needs
of the incident commander as it fails to
provide a low latency peer-to-peer
network capability and doesn't truly
address interagency, interoperability
requirements.
The public safety data market is changing
as existing CDPD WAN services used by
many public agencies are being phased
out. AT&T has notified customers that it
will no longer sell CDPD after March
2003 and the network will no longer be
supported after June 2004. Agencies will
need to migrate to alternative networks
such as 1xrtt CDMA or GPRS data
services, which are priced above current
CDPD network access charges.
Soon, the recently completed 5.9 GHz
DSRC standard will introduce a radio
platform for delivery of public safety
messages to the traveling public from
roadside infrastructure and public safety
vehicles. Other applications such as
traffic signal preemption may utilize
DSRC radio links between the public
safety vehicle and traffic signals at the
intersection.
The standards process to determine how
the 4.940 - 4.990 GHz spectrum will be
deployed into an interoperable standard
has not been determined. In the past
some vendors have supplied proprietary
solutions that lock agencies into a vendor.
While some vendor standards are
supposedly open, in practice customers
have found that the systems work best if
all the radios come from the same vendor.
The Concept
Leverage the standards developed by the
DSRC (Dedicated Short Range
Communications) standards committee
under ASTM 17.51 for ITS (Intelligent
Transportation Systems) communications
into 4.9 GHz Public Safety / Public

Service raclios. DSRC raclios will be
installed into virtually all Public Safety
vehicles early in the DSRC deployment
cycle. If Public Safety vehicles were to
also deploy 4.9 GHz raclios using DSRC
standards, they would have a low cost,
open, standards based, high performance,
interoperable raclio platform.
Integrate the local area network links
provided by 4.9 GHz Public Safety and
5.9 GHz DSRC raclios with cellular data
raclios to provide an integrated solution
that can provide both localized ad-hoc
peer-to-peer broadband services and
WAN services. Extend the capability of
the local broadband network with
MANET (Mobile Ad hoc NETworking)
protocols that can connect the wireless
broadband network into broadband
wireline metropolitan or global networks.
Increase Public Safety network
performance by inclucling approved
private operators to join the MANET so
they may assist Public Safety
communications over 4.9/5.9/802.11
networks by allowing Public Safety access
to their broadband DSL / Cable Modem
Internet connection via a 4.9/5.9/802.11
AP. This concept is similar to that
employed by ARES (Amateur Raclio
Emergency Service) / RACES (Raclio
Amateur Civil Emergency Service) or
REACT (Raclio Emergency Associated
Communications Teams) which promotes
the use of GMRS raclios on the
467.675/462.675 MHz repeater pair w/
repeater activation [PL] tone of 141.3 Hz.
Benefits of Leveraging 5.9 GHz
DSRC Standards for 4.9 GHz
The DSRC L1 /L2 (Layer 1 & 2 of the
OSI model) standard (ASTM 2213-02) is
based on the IEEE 802.11a standard.
IEEE 802.11a hardware operates
internationally in various spectrum blocks
from as low as 4.900 GHz in Japan to as
high as 5.825 GHz, upper UNII
(Unlicensed National Information
Infrastructure) band in the USA. As 5.9
GHz DSRC spectrum 5.850 - 5.925 GHz,
is only 100 MHz away from the upper
UNII band, some 802.11 a hardware
platforms can be "stretched" to provide a
RF unit capable of servicing channels
between 4.900 and 5.925 GHz. For 4.9
GHz Public Safety, no significant changes
of many existing 4.9 GHz Japan market
802.11 raclio hardware is required, other
than firmware updates to provide a 4.9
GHz raclio that operates under DSRC
standards.
The DSRC standards committee stuclied
and conducted tests to evaluate various
raclio technologies and by an
overwhelming vote, selected 802.11 a
operating in 10 MHz channels as the
preferred technology. The changes from
the IEEE 802.11 a standard were kept to a
minimum, while assuring that the solution
would meet the unique requirements of
the DSRC environment. For example, 10
MHz channels were determined to
provide a superior RF waveform for high
speed environments with multipath and
doppler shift impacts, than the 20 MHz
channels in the IEEE 802.11a standard.
A byproduct of the IEEE 802.11a
standard raclio platform winning the
technical competition over competing
raclio technologies is that, DSRC will be
based on a widely deployed, proven, low
cost raclio platform. DSRC will enjoy any
improvements made in 802.11 to address
the broad 802.11 market, without having
to develop new improvements specific to
the DSRC platform. The DSRC platform
can easily incorporate 802.11 standards
such as 802.11e Quality of Service (QoS),
802.11h Dynamic Frequency Selection
(DFS) and Transmit Power Control
(TPC), 802.11i Security, 802.11d

Internationalization, and any other new
protocols and technologies developed by
the IEEE 802.11 community.
Above the DSRC ASTM 2213-02 Ll/L2
~tandard, the DSRC roadmap is to
lncorporate the IETF (Internet
Engineering Task Force) RFC (Request
For Comment) 3095 ROHC (Robust
Header Compression) standard. The
DSRC committee has voted and passed
unanimously to incorporate IETF RFC
3095 into the DSRC standard. This will
allow for easy integration with ISO
(International Standards Organization)
TC204 CALMS architecture, which calls
for IPv6 as the networking layer for
International ITS platforms in the vehicle.
The incorporation of IETF RFC 3095
ROHC header compression can eliminate
or reduce the 40+ byte IPv6 header to 1-3
bytes and also enables compression of
other protocol headers. The over-the-air
transmission overhead of conforming to
ISO CALMS IPv6 standards in the North
American DSRC standard is eliminated
with header compression.
IPv6 provides superior support for
Mobil~ IP and security. The addressing
spac~ In IPv6 permits a variety of local,
locatlon based, regional and global
addressing schemes. This also provides
nodes to be deployed with common
Internet protocols and application tools.
The ISO IPv6 CALMS architecture allows
for integration of multiple data sources
into the in-vehicle network. A vehicle
may have data inputs from a 5 GHz
DSRC radio, Cellular Data radio Satellite
and vehicle sensors (radar, IR: etc.) t~
make ITS decisions. As DSRC provides
for compliance with the ISO IPv6
~ALM~ architecture, it supports easy
lntegratlon of a 4.9 GHz public safety
radio into an ISO IPv6 CALMS
architecture platform.
Public Safety Communications Networks
4.9/5.9 GHz Radio Integration
Suggestions
If the 4.9 GHz Public Safety Standards
Committee were to adopt the 10 MHz
channelization scheme of DSRC, it would
provide superior radio performance in
communication environments with
moving vehicles, than 20 MHz channels in
the IEEE 802.11 a standard. This
approach would also provide five (5)
channels in the spectrum, rather than only
two (2) channels with 20 MHz channels.
As an option, one can provide for 20
MHz channels by combining two (2) 10
MHz channels as the DSRC channel plan
provides for combining 10 MHz channels
180 and 182 into a 20 MHz channel 181
or combining channels 174 and 176 into a
20 MHz channel 175.
The DSRC standard uses a Control
Channel and Service Channel concept. If
we assume that DSRC and 4.9 GHz
public safety radios will both be deployed
on public safety vehicles, if a control /
service channel scheme is required for any
4.9 GHz applications, the 5.9 DSRC
control channel could be used for
applications that operate in the 4.9 GHz
band. This would allow for full use of the
five (5) channels in the 4.9 GHz band as
service channels for public safety
applications.
For 4.9 GHz radio operation, we could
more closely adhere to 802.11 standards
and use 802.11 beacons and 802.11h DFS
for channel selection, rather than the
control channel / service channel scheme
of 5.9 GHz DSRC. This would reduce
complexity of the stack. DSRC service
channel application providers will most
likely operate under standard 802.11
protocols, as suggested for 4.9 GHz radio
operations.

Public Safety Communications Networks
If NPSTC, IMSA, APCO, AASHTO and
other Public Safety organizations would
support the application of DSRC
standards to the 4.9 GHz band, it would
allow for hardware to be quickly
introduced into the market. The
deployment environment for 4.9 GHz
public safety has many characteristics of
5.9 GHz DSRC, so let's leverage the work
that has been done in DSRC to speed to
market an interoperable, high
performance 4.9 GHz radio platform with
a low investment requirement.
Additional Needs for 4.9 GHz
Public Safety Deployments
While DSRC applications are typically
short range and generally operate in
broadcast or one-to-one environments,
proposed collaborative interagency
applications in disaster / incident
management scenarios will require a more
sophisticated networking environment.
The need to multicast data to groups of
nodes by agency or location and the ability
to extend the limited range of radios that
operate in the 4.9 GHz spectrum leads
one to incorporate a MANET (Mobile Ad
hoc NETworking) protocol into any
proposed 4.9 GHz Public Safety radio
standard. This concurs with the
conclusion of other organizations looking
to develop global standards for public
safety broadband networks, such as
Project Mesa.
MANET is an IETF working group.
Applications that would operate over a 4.9
GHz Public Safety MANET, will most
likely need a pro-active MANET protocol,
such as TBRPF (fopology Broadcast
Reverse Path Forwarding), to assure low
latency network operations.
~
~
\," ......, ......
~..".
..Il
. - -- - - .
While one can use a proprietary MANET
protocol such as that employed by Mesh
Networks, a protocol that is standards
based and has undergone peer review at
the IETF would appear to be a superior
roadmap. This standards based approach
will not lock public safety agencies into
only deploying equipment from a sole
source vendor. Project Mesa also believes
that an open standard is preferable to
proprietary MANET protocols, provided
such a protocol meets application
requirements.
Integration of 4.9 I 5.9 Network
Links
Another byproduct of an integrated 4.9 /
5.9 approach is the synergy of 4.9 with 5.9
on an integrated platform provides greater
performance. The one (1) GHz spacing
between 4.9 and 5.9 provides for a
vehicle/node to conduct operations on
both radios simultaneously. One can't
operate on two 4.9 or two 5.9 channels at
the same time on the same vehicle, or in
close proximity, due to adjacent channel
interference. With an integrated
approach, half duplex radio links are
linked to provide a pseudo duplex link,
e.g. node 1 transmits on 4.9 and receives
on 5.9, while node 2 transmits on 5.9 and
receives on 4.9 spectrum. This network
topology will improve overall network
latency and throughput, especially in
MANET environments. Unidirectional
links avoid pausing for ACK
transmissions and improve streaming

application performance such as video or

vehicle can provide connection and
simultaneous operation of 4.9 / 5.9 /
Cellular and GPS receiver.
A Public Safety specific dual radio (4.9 /
5.9) may be possible to provide this
enhanced functionality to handheld form
factors too.
Multilink I Multiplexing of
Network Links
The basic MANET protocol(s) can be
enhanced to provide increased WAN
network data rates, WAN diversity &
capacity and overall network survivability.
As the 4.9 GHz network used at the
incident has substantially more capacity
than any projected 3G cellular network
roadmap, the 4.9 / 5.9 GHz network
could link to multiple cellular data radios
and multiplex the links to provide a higher
capacity virtual pipe. Perhaps EMS needs
to send medical information to the
hospital, idle cellular data radios in a fire
truck and police vehicle could be tapped
to provide 3x the WAN performance. If
public safety organizations were to utilize
several service providers they would enjoy
a more survivable and scalable network.
If one service provider's network was
down, the 4.9 / 5.9 GHz network could
route to a WAN link on vehicles equipped
with an alternative service provider
network. As any cellular data service
provider will have a maximum capacity of
only 2 Mbps in any given cell, network
diversity over several cellular data carriers
may also provide greater aggregate
capacity for public safety agencies.
Integration with Wireline
Networks
An interesting approach that some Florida
cities and counties are investigating is the
operation of a local public safety
Public Safety Communications Networks
communications MANET network over
ISM or UNII bands. Mesh Networks of
Orlando, Florida has deployed a test
network in Maitland, FL (Suburb of
Orlando, FL) to demonstrate such a
network on ISM spectrum.
If the Mesh Networks approach were to
be deployed over radios operating in the
4.9 GHz Public Safety spectrum, it would
offer public agencies the ability to connect
a broadband speeds at various locations
throughout the community, without
interference from civilian ISM or UNII
band, FCC Part 15 operations. When
such a connection is not available, Cellular
data or Public Safety data networks may
be used to connect the vehicles to public
safety networks.
The MANET approach would allow for
police equipped with handhelds that have
an integrated 4.9 GHz radio (example:
Toshiba's e740 and Compaq's h3950
Windows PocketPC handhelds have an
integrated 802.11 radio and many other
Palm or Microsoft handhelds have
expansion slots that could house a
4.9/802.11/DSRC radio) to connect to
their vehicle over 4.9 GHz, then link
through the vehicle's IPv6 network to
access the vehicle's cellular data network
radio or any other radio, including legacy
Public Safety analog or digital networks.
The Public Safety 4.9 GHz radio can be
the link between various devices / nodes
on the network.
If one were to adopt this proposal,
standardizing on 802.11 based technology,

Public Safety Communications Networks
a network architecture, USlng industry
standard radios, which provides
broadband (minimum DSRC radio data
rate is 6 Megabits / second) services
utilizing a combination of point to point
and multipoint to multipoint routing
topology is possible. The resulting
network, a Community Network
Infrastructure (CN!), will use a hybrid
wireline (DSL, T -1, Cable Modem, etc.)
and wireless architecture that provides
redundancy, increased network reliability
& survivability, improves network speeds
and delivers prioritized, constraint-
optimized bandwidth. It is anticipated
that a combination of licensed 4.9 Public
Safety, DSRC spectrum and unlicensed
UNII and ISM spectrum can be used to
provide services. There does not appear
to be any reason why a single 802.11 a
based radio card (pCMCIA, CF, SDIO,
mini-PCI, etc.) could not cover the
spectrum from 4.9 GHz Public Safety
through 5.9 GHz DSRC, including 5.1-5.3
GHz and 5.7-5.8 GHz UNII bands.
Another benefit of this approach is if
Multilink / Multiplexing of circuits, as
suggested for enhancing WAN cellular
data links, was applied to aggregation of
wireline ''Broadband'' links, it provides
improved performance from existing
''Broadband'' networks. Most
"Broadband" links are DSL or Cable
Modem links. These links are generally
asymmetric links, i.e. slow upload (128-
384Kbps) compared to download (up to
1,500 Kbps). As the minimum data rate
of the proposed 4.9 GHz PS radio
platform is a symmetric six (6) Mbps, it
will take several wireline ''Broadband''
connections to fully load a single channel
on the 4.9 GHz PS network either in the
upload or download direction.
Considering that many Public Safety field
applications have more upload than
download traffic, one would need to
Multilink / Multiplex 10-30 "Broadband"
DSL or Cable Modem links to provide the
capacity of one our of five (5) 4.9 GHz
public safety channels.
By delivering network services over a
CNI, wireline Internet connected
businesses, households, schools, libraries,
Police Stations, Fire Stations, City and
County offices, and other facilities could
install standardized wireless network
access points connected to their respective
wireline networks. If clear line of sight is
available, point to point links over the
wireless network can be up to 10 miles or
more. This scheme can be applied to a
private 4.9 GHz Public Safety only
network or public/private network
architectures. As more members are
integrated into the community network, it
improves network performance, provides
network diversity and redundancy. The
wireless network overlays the wireline
infrastructure to provide redundant links
between nodes and provide greater
capacity to any node on the network.
By allowing business, schools, non-profits,
home users, access to a CNI IP network,
that everyone can participate with a
minimal hardware (estimated at less than
$500 / node in volume) investment. We
enable community members to support
Public Safety communications as REACT,
RACES and ARES currently provide.
Essentially we link fixed 802.11 based
hotspots together with mobile (vehicles)
nodes to establish a public wireless data
fabric within the community. In exchange
for supporting the public community,
members may also benefit from access to
the network throughout the community.
Network Capacity Estimates
By using the standards based approach
suggested, licensed 4.9 GHz Public Safety
spectrum can provide five (5) Public
Safety channels, each with a minimum

data rate of 6 Mbps and maximum data
rate of 27 Mbps, or between 30 - 135
Mbps of capacity at any given physical
location. With a Community Network
Infrastructure (CN!), using industry
standard 802.11 technology, DSRC, UNII
and ISM networks can be integrated with
4.9 GHz Public Safety spectrum. This
will allow for twelve (12) UNII band
channels, each with a maximum data rate
of 54 Mbps and three (3) ISM band
channels, each with a maximum data rate
of 54 Mbps, or a total unlicensed
maximum bandwidth of 810 Mbps to
supplement Public Safety and DSRC
bandwidth of 135 Mbps each or 270
Mbps combined. The total maximum
wireless bandwidth available in any
physical area over 4.9 GHz Public Safety,
DSRC, UNII and ISM is 1,080 Mbps. At
data rates of 6 Mbps (slowest data rate
over 4.9 or DSRC) over 10 MHz channels
and 12 Mbps over 20 MHz UNII and
ISM channels, this still provides a
minimum of 240 Mbps of network
capacity at any physical location.
In the types of network conditions that
ETA proposes to deploy the CNI, the
data rate will be reduced from the
maximum to allow for longer-range
network links. With a CNI, the typical net
data payload capacity is expected to be
approximately 45% of the rated data rate
or typical minimum net data payload
capacity of 100 Mbps to be shared among
all users at a given physical location.
However, connection into wireline
networks can be provisioned periodically
to off-load the limited wireless capacity,
such that the 100 Mbps could be
provisioned per 1/4 mile in a microcell
architecture. In this example, each quarter
section or 160 acres of land area would
have approximately 100 Mbps of
aggregate capacity, thus the projected
capacity will exceed most all anticipated
demands. Additional transmit power and
antenna controls can be placed to reduce
the communication zones, to further
increase bandwidth per square foot
density if desired and if the wireline
backbone could handle the additional
load. Consider:
· Current Cable Modem networks
share 10 Mbps per 5,000 to 15,000
homes passed.
. With a home density of a home
per 114 acre, a minimum of 100
Mbps of wireless capacity would
be shared among 640 homes vs 10
Mbps shared among 5,000-15,000
homes in current cable modem
network deployments.
. The maximum aggregate data
bandwidth in a cellular data
network is typically 2 Mbps x 6
service providers or 12 Mbps,
while the CNI provides a
m1t111num aggregate data
bandwidth of 100 Mbps.
COTS Hardware Platform
DSRC and our proposed 4.9 Public Safety
communications platform, leverages
commodity COTS (Commercial Off-The-
Shelf) hardware technology to deliver a
cost effective, reliable, high performance
platform. The hardware requirements for
proposed CNI backbone nodes (flxed
nodes connected to wireline infrastructure
and vehicle platforms that contain two (2)
802.11 based radios and perhaps a Cellular
data radio too) will be substantially higher
than clients on handheld platforms that
attach to the backbone nodes.
To client devices, the CNI backbone
hardware may appear to be a standard
802.11 Access Point into the network.
802.11 wireless hardware is moving
toward universal adoption for many
mobile devices (notebooks, PDAs, cell
phones, etc.) and for SOHO networks.

By the end of 2003 a maJorlty of new

industry standard technology such as
802.11, for Public Safety 4.9 GHz wireless

Certainly 802.11 based COTS hardware

NPSTC Action Required
Your support is requested to begin the
Phase I tasks to move this forward:
. Draft what can be taken from the
5.9 DSRC standard for 4.9 Public
Safety
Public Safety Communications Networks
· Identify what in the DSRC
standard can be eliminated for 4.9
Public Safety
. Identify what in addition to the
DSRC standard is needed to
deploy networks to support
incident or disaster response team
applications from multiple public
safety organizations.
Our concept is to simply integrate COTS
and emerging technologies with proven
public safety communications concepts.
By leveraging a large installed base of
802.11 and DSRC infrastructure to
support 4.9 GHz operations, we enhance
public safety communications capabilities.
Mohan Pundari (ETA) would like your
support in obtaining grants or funding
from Public Safety agencies and the
Offlce of Homeland Security to further
develop these concepts. ETA is a federal
government certifIed 8a company, as such
federal agencies may contract with ETA
on a negotiated basis, without a lengthy
procurement process. This can speed
development of the concepts to address
immediate Public Safety communication
needs in the most efflcient, cost-effective
manner.

Intelligent Transportation System (ITS) Integration
DSRC / -to () (; IIz Puhlic Safet~. and \"1 IS
The Problem
DSRC standards will be completed in
2003. The VSCC ry ehicle Safety
Communications Consortium) is currendy
engaged in a joindy funded research
program with FHWA (Federal Highway
Administration) and NHTSA (National
Highway Transportation Safety
Administration) to develop safety
applications that are to be delivered over
DSRC. VSCC members have stated that
unless there is a national roadside
infrastructure that is delivering
information over DSRC, they will not
install DSRC into vehicles as OEM at the
point of manufacture. The automobile
manufacturers have stated that this is a
billion+ dollar investment for each of
them. Even if the decision is made to
embrace DSRC and deploy it at the OEM
level in 2004, after DSRC standards are
completed, no vehicles with DSRC will be
rolling off the assembly line until 2007-
2008 at the earliest, assuming strong
funding support (billions of dollars) by
USDOT to install roadside infrastructure
to deliver the safety applications by the
2007-2008 timeframe. Given this oudook
from the automobile OEM community,
aftermarket is the only area that has
potential to launch 5.9 GHz DSRC in the
next five (5) years.
The Concept
Provide the USDOT (Department of
Transportation) Office of Travel
Management with a framework to deliver
A TIS (Advanced Traveler Information
Services) over DSRC (Dedicated Short
Range Communications) radios developed
under ASTM 17.51 as the ITS (Intelligent
Transportation Systems) communications
platform to deliver many of the ITS
services envisioned the ITS America 10-
year Program Plan.
By moving to an integrated 4.9 / 5.9 GHz
radio platform at all locations that A TIS
information is delivered to the traveling
public, the wireline backbone that the
A TIS system is connected to, can also
provide all public safety agencies a
"Broadband" link to access their
applications. The incremental cost of
adding a 4.9 GHz radio is minimal, but
can provide significant benefits to the
public safety community. If schools, ftre
stations, police stations, city, county and
others that participate in a 4.9 GHz Public
Safety network add 5.9 GHz DSRC to
their network at a low incremental cost,
there are even more locations that A TIS
or other information that public agencies
want to deliver to the traveling public can
be transmitted from.
This integrated 4.9 / 5.9 concept can be
applied to any location that DSRC or 4.9
GHz Public Safety radios are installed. At
many intersections, traffic systems are
connected to DSL, T-1 or Fiber networks
that could provide backhaul capacity for
both 4.9 and 5.9 DSRC applications. This
approach may provide additional funding
sources for the DOT, from supporting
agencies such as the DHS (Department of
Homeland Security), to install integrated
4.9 / DSRC systems. As DSRC in the
vehicle will be the communications system
for the driving public to receive Public
Safety agency messages and other ITS

services provided by the DOT and local
transportation supporting agencies. If
authorized participants were to install at
their own expense, the integrated 4.9/ 5.9
system to assist public safety
communications, it would further increase
the capabilities of a 4.9 GHz Public Safety
communications system.
Why A TIS is The Best Plan to
Launch Integrated 4.9 / DSRC
The currently deployed or proposed A TIS
system deployments cover more than 50
major metro areas across the country, for
delivery of A TIS information to the
traveling public. By delivering this
information over DSRC at key decision
points along major highways and routes, it
fulfills the VSCC / automaker
requirement that a plan for nationwide
DSRC infrastructure is implemented
before DSRC is installed as OEM on
vehicles. If A TIS is delivered over DSRC
at police, fire, county, city and other
locations that plan to install 4.9 Public
Safety network access points, it further
assures the nationwide backbone
requirement by the VSCC / automakers is
met. Currently the plan for A TIS
information delivery to the traveling
public is over the Internet or IVR
(Interactive Voice Response) over the 511
system.
In Florida, A TIS systems are planned for
the Tampa Bay, Orlando, Jacksonville,
and South Florida (West Palm Beach
through Miami to Key West). Florida
plans to deliver A TIS information to the
public via the Internet and by having the
traveler call 511 on their cellular phone.
Concerns of this approach are:
· Most commuters are driver only
commuters, there isn't a second
passenger that can work the cell
phone and provide A TIS
information to the driver, so the
driver must work the cell phone.
. I thought we wanted to avoid
making calls while driving to
reduce accidents. By having
drivers call 511 to determine
current traffic status may cause
accidents, resulting in even greater
traffic delays.
· Having someone "surf' the web
over their GPRS or 1xrtt enabled
cell phone, while driving is likely
to be even more dangerous than
calling 511 for traffic information.
An alternative is to allow consumers to
install a DSRC radio, connected to a PDA
equipped with navigation software. Today
one can purchase navigation software that
provides turn-by-turn directions with
voice prompts on PDAs. If this software
were to receive A TIS data from roadside
DSRC infrastructure, it could enable
individualized dynamic route selection for
the consumer. Benefits include:
· The consumer would get to their
destination quicker with dynamic
route selection
· The DOT could delay roadway
expansion and construction by
having A TIS essentially "load
balance" traffic over existing road
infrastructure.
· Vehicles can be probe vehicles,
that report travel times on roads
that are not instrumented, thus
reducing the cost of ATIS
deployment, while enhancing the
number of route segments that
A TIS data is provided.
All of this is provided without driver
distractions. You simply drive to a
destination in your PDA address book
and software alerts the driver to an
alternative route, only if the situation

demands. No hands off the steering
wheel, working the cell phone for A TIS
information, while driving.
ATIS I DSRC Summary
Vehicles equipped with DSRC and
navigation system software can be
employed as probe vehicles to refIne and
extend A TIS beyond the major
instrumented roads. By leveraging DSRC
in vehicles the DOT will lower overall ITS
data collection costs.
With the proposed adoption of DSRC
technology for 4.9 GHz Public Safety
radios, a single low cost, industry standard
radio, promoted by the US DOT and
FHW A as the wireless communications
technology for ITS applications, can
provide portions of the data backhaul to
the TMC (frafflc Management Center),
provide A TIS information to the traveling
public, and collect probe data from the
traveling public back to the TMC (frafflc
Management Center), to further increase
the accuracy and reliability of the A TIS
information disseminated by the DOT.
As this is the wireless technology is
advocated by the USDOT, there is
considerable institutional support for
DSRC.
DSRC or 4.9 GHz links used by
instruments to transmit their data to the
TMC, can also deliver consolidated
information from the TMC to the
traveling public. The incremental cost for
A TIS information delivery to the public
over DSRC is very low, perhaps as low as
$200 million for a nationwide deployment,
for the major metro areas that will deploy
A TIS, which will address the needs of
over 70 % of all commuters.
FDOT Model Deployment
ETA has been in discussion with the
OffIce of Travel Management at the US
DOT regarding the use of DSRC with
A TIS. Discussions with USDOT indicate
that they would be willing to help a State
DOT fund a study on how this scheme
would work and to develop more detailed
system architecture plans. This
preliminary study would then be used as
the project plan for a model deployment
in 2004.
Florida DOT Proposal
ETA has made a proposal to FDOT for
this model deployment. The proposed
team would combine FDOT, Florida
Public Safety Communications offlcials,
and McTrans at the University of Florida
with ETA to develop the system
architecture plan. A report delineating
how this would all work and identifying
the development work needed to have a
model deployment in 2004 is the goal of
Stage One.
. FDOT - ITS applications
· Public Safety Officials - Public
Safety application overlay
· McTrans - Leverage the work
they have done for deploying
microcomputers in transportation.
Application development
. ETA - DSRC knowledge and
systems integration
Although the model deployment will
focus on A TIS, the data backbone and
DSRC roadside infrastructure will be
designed to support any and all
applications for DSRC and Public Safety
applications. Integrating 4.9 GHz Public
Safety into the project will greatly enhance
the usefulness of the resulting network as
Public Safety organizations (FDLE, FHP,
Sheriffs, Police, Fire, Ambulance, etc.) will
have network access everywhere FDOT
DSRC I 4.9 GHz infrastructure is located.
