– Equipment expensive, outdated, and proprietary
– Primarily narrowband voice and data communications
– Lack of survivable communications
– Does not support high density incidents
• Spectrum
– Fragmented
– Limited availability
• Funding
– Limited and fragmented funding
– Communications technology not a priority
• Lifecycle Costs
– Inflexible systems and complex deployments

Last Word . . .
“As demonstrated in a live field exercise, PacketHop was able to achieve mobile broadband connectivity across tough
terrain—on land and water—and over mobile, infrastructure-less networks for more than ten multi-jurisdiction agencies.
This exercise was unquestionably an important milestone in driving the Golden Gate Safety Network closer to its vision
to develop and implement a regional communications system that supports a multi-agency response from local, state
and federal first responders for day-to-day operations and incident management.”
Michael Griffin, Assistant Chief
CA Governor’s Office of Emergency Services
“Stationed at the Emergency Operations Center in Sacramento—over 100 miles from the incident command center in
San Francisco—we were able to see the exact location of first responders as they moved, downloading maps, sending
messages and sharing video. PacketHop can be an invaluable tool in enabling survivable, remote connectivity, which
means we won't have to rely on broadcast news helicopters for on-the-scene updates or follow along by phone/
radio. We could source real-time intelligence from the first responders in the field on land, sea or air."
George Lowry, Assistant Chief, Telecommunications
CA Governor’s Office of Emergency Services
“Mobile mesh networking technology, like PacketHop’s, allows multiple agencies to instantaneously exchange critical
multimedia information while working seamlessly between assorted devices, across differing spectrum channels and in-
and-out of networks. For the first time, police, fire, federal agencies, military and other first responders were able to
share rich, mission-critical, real-time intelligence, by leveraging commercial off-the-shelf equipment.”

PacketHop & 4.9Ghz
• PacketHop supports COTS approach to 4.9Ghz
– 802.11a as proxy
– 802.11j (Japan unlicensed radios in 4.9Ghz)
– Minor software change using COTS radios
• Advantages:
– Low cost
– Easily “upgraded” with software networking interface
– Enables competition
• NPSTC
– Numerous presentations to NPSTC BOD
– NPSTC “adopted” PacketHop network as example in latest
submission (12/03)
• PacketHop / NPSTC submission to FCC in support of
COTS for 4.9Ghz radios
• GGSN Trial: Use 802.11a as proxy for future 4.9Ghz
