The unfortunate corollary to this maxim: Communication failures kill. More attention is being focused on how to improve communication, not only within an emergency response organization, but also among first responders from different agencies. To remain fully connected, key communications officers have often adopted a "Bat Belt" approach with several communications devices - sometimes a half dozen or more - strapped to their waist. It's a necessity for communicating among the many federal, state and local agencies' wireless networks during an incident.
Today's IT is increasingly sophisticated, and emergency response agencies and hardware platforms are proliferating, which makes interoperable communications ever more urgent. Natural or man-made disasters require close interaction of many organizations, but the sad reality is that too many communications systems aren't interoperable; this can lead to on-the-ground snafus, inefficiency and tragedies - as was exemplified in the disaster response after Hurricane Katrina. Within these contexts, the FCC is working to open new radio frequencies to meet first responders' interoperability needs.
Current FCC proceedings focus on creating a nationwide public-safety band for wireless communications among first responders. Ryan Hallahan and Jon Peha sum up the opportunities this rulemaking holds in their 2008 paper, Quantifying the Costs of a Nationwide Broadband Public Safety Wireless Network: "The problems facing the public safety wireless communication systems in the U.S. could be significantly reduced or eliminated through the deployment of a single nationwide network that serves all public safety personnel." On Sept. 25, 2008, the FCC released a Third Further Notice of Proposed Rulemaking after the auction for the proposed public safety band failed to achieve its reserve price. The third notice strives to achieve "the goal of a nationwide interoperable broadband wireless network for public safety entities."
Although municipal CIOs and public safety leaders have welcomed reserving a band for interoperable public safety communications, details have proven hard to nail down. With the proceeding dragging into its third year, public safety representatives - frustrated with the lack of significant progress and faced with the daily difficulties associated with many noninterconnected systems - have begun to organize and weigh in. Many of them believe the 700 MHz band could potentially let them upgrade existing infrastructures - adding services, applications, speed and interoperability in one swoop. For municipalities seeking to transition from analog systems to digital networks, the 700 MHz band provides a once-in-a-generation opportunity for an across-the-board upgrade.
Existing Emergency Response Networks' Challenges
Today's emergency responders use several communications devices, which are often tailored to the constituencies they serve. Thus, fire responder radios are built to ensure that their equipment doesn't generate electronical sparks; this makes them safe to use during gas leaks. Though this is obviously necessary, problems arise, for example, when fire responder and police radios that operate on different systems can't communicate effectively with each other.Michelle Geddes, interoperability program manager of San Francisco's Department of Emergency Management, said two major challenges exist: voice interoperability and data operability. To facilitate this, Project 25 (P25) was created to develop interoperable, digital communications standards for emergency responders. "In terms of voice communications, the P25 standards are just being ratified, and a standards-based product is slowly coming to market," Geddes said. "The cost for the P25 technology is still extremely high, most likely due to the small market for these systems, making it financially difficult for municipalities to afford these networks."
But once the affordable hardware is available, there's still the problem of accessing public airwaves. According to Geddes, the 700 MHz public safety proceedings are supposed to solve the problem that "municipalities don't have a viable spectrum option to deploy ubiquitous wireless broadband systems within their jurisdictions." Currently municipalities tend to get by with the creation of systems kludged together from suboptimal spectrum bands - usually 2.4 GHz and 5 GHz (i.e., Wi-Fi) and 4.9 GHz
public safety bands. The quick rule of thumb is that the higher the frequency, the worse the propagation characteristics. Therefore, the 700 MHz band offers superior connectivity over distances and through barriers that Wi-Fi could never reach. Experts familiar with the technology say that 700 MHz networks may need only 25 percent of the base stations that are needed for ubiquitous coverage at higher frequencies.
The 700 MHz bands that the FCC attempted to auction (758-763 MHz and 788-793 MHz) were used for over-the-air TV channels 62 and 67. With the digital TV transition - all TV over-the-air broadcasts will switch to digital broadcasting on Feb. 17, 2009 - these channels were vacated. The FCC auctioned licenses to use these frequencies with the caveat that the winner of this so-called "D Block" would be mandated to partner with public safety constituencies to use the adjacent public safety broadband spectrum (conveniently located at 763-768 MHz and 793-798 MHz). Through a network-sharing agreement, the FCC's goal was to create a unified, commercial/public safety network.
In theory, this sounds like a good plan, but the on-the-ground reality proves difficult to overcome. Because there's confusion about the requirements of interoperability and network sharing, the original reserve price was never met, thereby sending the idea back to the drawing board. For public safety constituencies, the notion that a private entity would control the entire infrastructure - and consequently could charge monopolistic rents - has been a major concern. For example, Paul J. Cosgrave, commissioner of the New York City Department of Information Technology and Telecommunications (DOIT), raised the concern that potential providers have floated the idea of a $49 per month charge for each device on the network. Cosgrave said the New York City Police Department has 30,000 to 40,000 people, so for one year's service the city would have to pay $17.6 million to $23.5 million just for the police department - a base price that almost certainly excludes add-on services and taxes, which could increase the price tag another $15 million to $25 million. These costs make such networks prohibitively expensive for most communities.
Without an alternative, public safety officials are forced to swallow a bitter pill. As Geddes lamented, for communities that lack access to adequate spectrum, "The only other option is for local government to pay monthly service charges for subscription-based wireless broadband service through a carrier-based service like AT and T or Verizon - these services are vulnerable in emergency situations and are typically overwhelmed and unreliable in the event of a major incident."
Cosgrave leads his city's effort to develop a proof-of-concept implementation. According to a letter from New York City DOIT to the FCC, the "project was proposed to serve as a national model for next-generation public safety radio systems." Cosgrave pointed out that the needs of responders often vary by geography. As such, a single, nationwide network may be a suboptimal solution for many locations. "An FCC-mandated, one-size-fits-all solution fails to take into account some fundamental facts," Cosgrave said. "In NYC the tall buildings are quite different than, for example, out West with its wide-open areas; a national standard isn't going to work [for everyone]."
Effects of the 700 MHz Auction
Though many experts have noted that the 700 MHz auction is a flawed process for maximizing the benefits to public safety, the auction was mandated by a 2005 telecommunications bill sponsored by Arizona Sen. John McCain. This means that the FCC is somewhat tied - it is required to auction spectrums to the highest bidder, all but guaranteeing that a private entity will manage the network's deployment and ongoing operations. Municipal leaders fear that the build-out timeline of 15 years is so long that it's likely any technology deployed would likely be obsolete by the time many portions of the network are actually built, which would create the potential for future interoperability headaches. In addition, second- and third-tier communities could wait until 2020or beyond before the network is deployed in their areas.
Ideally the 700 MHz spectrum provides many chances for local communities to deploy state-of-the-art wireless networks. Geddes said this spectrum lets local governments run more efficiently and gives first responders enhanced tools to respond to emergencies. According to Barry Fraser, telecommunications policy analyst for the San Francisco Department of Technology, "We would want to be able to use it daily for general public safety - police, fire, EMS [emergency medical services]."
Municipalities envision public safety applications that facilitate a variety of services including:
- helping police by sending videos of crimes or events to an incident command center;
- aiding building inspectors and fire responders with real-time updates of mapping information and the ability to download building blueprints; and
- helping paramedics and doctors with remote medical diagnoses and treatments.
Telling it to the FCC
While private interests demanded a 15-year build-out schedule, local municipal leaders are now ready to begin deploying networks. "I would be deploying my wireless network on 700 MHz if it were available tomorrow - it will enable us to do things we've never been able to do - that's the bottom line," said Donald Denning Jr., public safety CIO of Boston.City officials are deeply concerned about the way the 700 MHz public safety band has been handled so far. Cosgrave declared the auction process "flawed" because of its focus on a single, national license. Though the regional licensure is seen as a step in the right direction, William Oates, CIO of Boston, provided a succinct analysis of the main concerns officials have raised: "Our biggest issue is to have access to this spectrum so that, from a city and regional level, we can solve the information-sharing issues in front of us. If we have to wait for the service provider, we're not sure if this will be a viable option."
Todd Sander, director of Government Technology's Digital Communities program, organized an event in Miami in June 2008 that gathered representatives from major metropolitan areas. The meeting revealed that emergency responders nationwide had the same issues. Fundamentally there was tension between the profit-driven focus of commercial enterprises and the public safety goals of emergency responders. "We had little confidence that something useful would come out of that for the city - a commercial-quality network likely would not be good enough in an emergency," Sander said.
Subsequently public safety officials and CIOs from many of the largest U.S. cities and counties banded together through the Digital Communities 700 MHz working group to protest the FCC's new proposed rules for the 700 MHz D Block auction. In a letter to FCC Chairman Kevin J. Martin, they argued that the FCC plan to pair the public safety spectrum with the commercially auctioned "D Block" of spectrum "will fall far short of satisfying a once-in-a-lifetime opportunity to fix the weaknesses in the core structure of public safety spectrum." And they added, "We do not believe that the current plans to auction
the D Block will in any way be a solution to the public safety wireless broadband needs in our communities."
Efficiencies are a main reason why local decision-makers are so interested in the 700 MHz band. "Convergence and interoperability are the future of municipal IT," Geddes wrote. "It is the ability for every city agency ... to access the information they need, wherever they are. It is the ability for any municipal worker to take advantage of existing assets or new technology resources to perform their functions effectively."
"Optimizing resources is a high priority, as are speed of deployment and ease of maintenance," Oates said. "We need to deliver data to public safety equipment in ambulances, fire apparatus and cruisers - we need a broadband solution for the mobile world." He said the city examined Wi-Fi and 4.9 GHz radios, but they aren't adequate for next-generation networking. The failure of the first D Block auction was problematic because it slowed down a process that many feel has been dragging. "We have a sense of urgency," Oates said.
Boston's Denning concurred that the city ready to deploy these next-generation communications networks immediately. "We have a fairly good idea for the propagation characteristics because of our 800 MHz network [and want a 700 MHz network] within the next 24 months." In the meantime, as Oates said, "We'll do this with 2.4 or 4.9 [GHz] if we can't get 700 MHz, [but] height and penetration into buildings would be greatly improved with 700 MHz."
Although municipal authorities are ready to begin building next-generation networks right away, in the end, it may come down to political expediency rather than public safety. Between the recent financial meltdown that has undermined attempts to auction spectrum licenses and the political transitions happening in Washington, D.C., it's unclear how quickly the FCC will move to create this interoperable public safety band.
Municipal representatives suggest that the FCC set some basic interoperability standards and then let local governments build the networks they need immediately. Although the FCC faces a mandate to auction some of the spectrum, many municipal IT professionals feel that the FCC should provide early access to the spectrum for those communities that are ready to deploy now.
In New York, Boston, San Francisco and elsewhere, officials are eager to deploy public safety networks. By setting basic requirements, the FCC could ensure that these systems would interoperate across municipal boundaries without further slowing the speed of implementation. "We already operate an 800 MHz wireless network - we have the towers and backhaul infrastructure in place. It would just be a matter of buying the radios, installing them and connecting them to our backhaul," Fraser said. "The locations we already have selected would equate very closely to the layout you would need for a 700 MHz system."
Cosgrave sums up the concerns of many public safety officials: "We're very uncomfortable about [the auction process]; it's set up for carriers and doesn't really meet the basic standards for public safety networks."
After Hurricane Katrina, many of the lessons learned during disaster recovery efforts were reported to the FCC. Despite those proposed recommendations, local municipalities were forced to implement suboptimal emergency wireless solutions while waiting for the FCC to move forward with the 700 MHz public safety band proceedings. In the end, many emergency response wireless networks remain noninteroperable - worrying officials who are all too aware of the consequences of noncommunication.
