Sept. 11, 2006 — In the minutes, hours and even days following the disasters of 9-11 and Hurricane Katrina, rescue workers struggled with the simple task of communicating.
The problems were many and varied, but can be blamed in part on old fashioned, incompatible technology and a fragmented infrastructure.
At least two plans to update public safety communications are before the Federal Communications Commission — one from Verizon Wireless and the other from Cyren Call, founded by Morgan O'Brien, co-founder of Nextel.
Both plans propose a partnership between private and public sectors to establish a broadband wireless national network that would stimulate technological innovation to make communications compatible.
"We're, right now, at a total paradigm shift that is being driven by the wireless industry," said Ron Haraseth, director of Daytona Beach, Fl-based Automated Frequency Coordination, which provides licensing-related services for public safety.
Broadband would give tens of thousands of public safety agencies the ability to transmit text, images, files, even streaming audio and video from a disaster or crime scene.
Can You Hear Me Now?
The current system was designed with key factors in mind, but it has major drawbacks.
Most of the time, rescue workers need to speak only with other members of their team, so they use a radio channel dedicated just to them. They also need a network that won't get overloaded with calls during an emergency. So they lease radio spectrum on a local network guaranteed to be wide open at all times.
But because emergency workers use a dedicated radio channel, they usually don't know what channels other responders use. Plus, a local network devoted to local units doesn't work if those people are asked to respond to a disaster in another country or, in the case of Hurricane Katrina, another state.
Responders use two-way "walkie-talkie" radios since they need the ability for one person, such as a fire chief, to speak with many at once.
The problem is the commercial market for walkie-talkies is small compared to other devices, such as cell phones. There are about 2.5 million first responders in the United States compared to more than 200 million cell phone subscribers.
The small market drives prices sky-high. As a result, departments keep their equipment for decades. And a lack of manufacturing standards means that older systems are often incompatible with newer ones.
This kind of incompatibility, as well as channel overload, made it impossible on September 11 for police officers and firefighters in the North Tower to receive radio calls that the South Tower had collapsed, according to the 9/11 Commission Report.
National Network
A national network based on a partnership between the public and private sectors could boost public safety communication technology into the 21st century.
Both the Cyren Call and Verizon proposals deal with a coveted swath of radio spectrum being vacated by television broadcasters, who are moving to another spectrum more suitable for digital television.
Signals in this spectrum are ideal for pubic safety because they can travel up to 30 miles, can penetrate walls and can be sent and received without a direct line of sight to a tower.
The FCC has already set aside some slices of the prime spectrum for public safety use. But it plans to auction the rest for billions of dollars to commercial wireless carries.
Cyren Call, who announced their proposal last April, is trying to persuade Congress and the FCC not to auction the slices of spectrum, but to put them into a public trust.
They propose that the trust then hire a company like Cyren Call to manage it. They envision a network could be up and running by 2009.
"If they decided that they didn't need that or did not want that role to be played by us, so be it," said Morgan O'Brien, founder of Cyren Call.
According to John Melcher, executive vice president of Cyren Call, the spectrum could accommodate 60 to 70 million broadband subscribers. Nationwide, there are only 2.5 million emergency responders.
The idea is to lease the excess space to private companies. The large number of subscribers — among them the public safety workers — would presumably drive up competition and technological innovation.
Money from the leases would pay back Congress the billions of dollars it was expecting from the auction, O'Brien explains.
"The challenge in building a system is ensuring that the public safety system has the priority," said David Boyd, director of Department of Homeland Security's Office of Interoperability and Compatibility.
That could be accomplished, said Melcher, by coding the packets of digital data traveling in the signals so that emergency responders would have priority over civilians.
The unofficial Verizon Wireless plan deals with slices of spectrum already set aside for public safety. Verizon did not respond to requests for comments on the project.
Could it Work?
Cyren Call's current plan proposes coverage wherever the population density is more than five people per square mile. That equals about 99 percent of the U.S. population. Satellites, which offer slightly delayed signals, would fill in the gaps.
The small gaps in service have some emergency responders in rural areas concerned.
"If someone is out there taking shots at you, five seconds is an eternity when you're trying to get help," said Joe Peters, director of technology assistance division of the Sheriff's Association of Texas in Austin.
And according to Boyd, the biggest problem facing public safety communications is "primarily a human one."
Even if emergency groups are able to talk to each other, they'll need to come up with a common language that doesn't break down during big disasters.
The FCC plans to auction the prime spectrum in January 2008. If the public safety communications remain status quo, rescue units will continue to strive for coordinated systems. It just may take longer.
A comprehensive program known as SAFECOM run by DHS's Office for Interoperability and Compatibility estimates fully integrated systems will be in effect within twenty years.
