Public Safety Communications and Spectrum Resources: Policy Issues for Congress 
Released: 2010-09-01T00:00:00

Summary: Effective emergency response is dependent on wireless communications. To minimize communications failures during and after a crisis requires ongoing improvements in emergency communications capacity and capability. The availability of radio frequency spectrum is considered essential to developing a modern, interoperable communications network for public safety. Also critical are (1) building the network to use this spectrum and (2) developing and deploying the radios to the new standards required for mobile broadband. Beyond recognition of these common needs and goals, opinions diverge on such issues as how much spectrum should be made available for public safety broadband communications, how communications networks should be configured, who should own them, who should build them, who should operate them, who should be allowed to use them, and how they might be paid for.

Three bills that would increase the amount of radio frequency spectrum assigned for public safety use have been introduced. The bills would require that the Federal Communications Commission (FCC) transfer a spectrum license intended for commercial use, known as the D Block, to the license-holder for adjacent frequencies already assigned to public safety, known as the Public Safety Broadband License. The Broadband for First Responders Act of 2010 (H.R. 5081, Representative King) deals primarily with reassignment of the D Block. Two Senate bills contain similar provisions for spectrum assignment and would add a number of new provisions, including using the proceeds of future spectrum auctions to fund the needed network (S. 3625, Senator Lieberman and S. 3756, Senator Rockefeller). The development of public safety radios for broadband would be expedited by companion bills H.R. 5907 (Representative Harman) and S. 3731 (Senator Warner). Public safety operations would benefit from the radio-development initiative regardless of the eventual assignment of the D Block. Congress may consider additional legislation or oversight to meet desired levels of emergency communications performance.

Among the actions that Congress might take, those dealing with governance and funding are often cited by public safety officials and others as the areas most in need of its consideration. Many have recommended that, for the proposed broadband network projects to go forward on a sustainable footing, funding sources need to be identified for investment and operating expenses over the long term. To ensure the resources are wisely used, some analysts point to the primacy of putting in place a well-grounded but flexible governance structure. The debate on spectrum assignment has in recent months dominated the attention of Congress and other policy makers. Meanwhile, several states and urban areas including the San Francisco Bay Area, Boston, and the State of Mississippi have submitted detailed plans for building the nation's first broadband networks that might serve as a practical framework for evaluating policy options. These plans, developed according to FCC requirements, share many common features. Notable from a policy point of view are several recommendations that provide a common theme in these early submissions. These may be summarized as: (1) sufficient funding is essential; (2) networks that either cover an area designated as eligible for Urban Area Security Initiative programs, or cover a regional area—that is, large and/or densely populated areas—are more efficient to build, operate, and govern; (3) several critical technologies and standards, such as for radios, must be developed before the networks can be fully effective; (4) some form of governing sur-structure must be in place to assure uniformity of core operations while allowing for local customization of public safety applications; and (5) collaboration with commercial partners is important for mustering all the skills and knowledge resources needed for developing the leading-edge broadband networks that are the goals of the submitted plans.


subsections: section_title: The Issues Before Congress
paragraphs: Since September 11, 2001, Congress has passed several significant pieces of legislation intended to help surmount failures in public safety radio communications such as (1) insufficient interoperability among radio systems, a problem that hampered rescue efforts on and after September 11; and (2) insufficiently robust networks, a shortcoming revealed after Hurricane Katrina struck in August 2005. To achieve a higher standard of communications performance might require, among other elements, improvements in communications capacity and quality. Increased capacity is achievable through a number of means. Increasing the amount of radio frequencies available for public safety use is one solution for adding capacity. Building additional infrastructure to use existing airwaves more effectively is another solution, as is investment in more spectrum-efficient technologies. Sharing networks also can provide additional capacity for operations. All of these measures have been proposed for improving public safety communications, with different groups voicing preferences for one means over another. 

Many representative of the public safety community have argued that additional spectrum assignments are needed to meet the future needs of emergency communications, while the Federal Communications Commission (FCC) has presented an action plan that would develop capacity through investing in network infrastructure, public-private sharing of development costs for efficient radios, and creating a regulatory regime that would allow public safety and commercial users to share infrastructure. All of the measures under consideration by the FCC or proposed by public safety agencies would require substantial funding—many billions of dollars—of which some is expected to come from the federal government.

Three bills have been introduced that would require the FCC to assign additional spectrum, known as the D Block, for a public safety broadband network and take steps to ensure construction of an interoperable network. A draft discussion bill was released in June that would support the FCC's plans for using spectrum and developing infrastructure, funded in part by auction proceeds that would include the sale of the D Block. These bills deal lightly with the question of governance, for the most part making adjustments to the regulatory and oversight responsibilities of the FCC. 

The Next Generation Public Safety Device Act of 2010 ( H.R. 5907 , Representative Harman) and its companion bill ( S. 3731 , Senator Warner) are more narrowly focused on a critical initial step on the long road to assuring that a nationwide, interoperable network is put in place for public safety communications: the radios. The FCC has linked the auction of the D Block to the development of the needed public safety features for broadband radios that would operate on the D Block network frequencies, the Public Safety Broadband License frequencies, and perhaps other frequencies within the band. In the FCC's announced plans, the D Block license-holder(s) would take the lead in, and assume the costs of, developing appropriate hardware and software for radios used by public safety. The FCC, in the NBP, stated that details of how these requirements would be determined and enforced would likely be decided as part of the comment process that would lead up to the auction, with development work starting after a successfully completed auction. The Public Safety Device Act would begin the process of development almost immediately and would encourage innovation and competitive pricing through a technology competition administered by the National Telecommunications and Information Administration (NTIA).

section_title: Debate Over Spectrum Resources: The D Block
paragraphs: Congress last addressed the public safety community's need for spectrum capacity by mandating the release of 24 MHz of frequencies that were originally designated for public safety use in the late 1990s. This crucial resource, part of the 700 MHz band, remained largely unavailable as long as its airwaves were used for analog television transmissions. By providing a deadline for the transition from analog to digital television, Congress ensured that valuable radio frequency spectrum would be released by 2009. 

The assignment of one set of frequencies in the 700 MHz band, referred to as the D Block, has been widely debated. The D Block was slated for auction in 2008 along with other available frequencies identified in the Deficit Reduction Act of 2005. In compliance with instructions from Congress to auction all unallocated spectrum in this band, the FCC conducted an auction, which concluded on March 18, 2008. As part of its preparation for the auction (Auction 73), the FCC sought to increase the amount of spectrum available to public safety users in the 700 MHz band. The FCC proposed to assign 10 MHz—part of the original 24 MHz designated for public safety use—to a Public Safety Broadband Licensee specifically for public safety broadband communications. Of the balance, 12 MHz were designated for mission critical voice communications on narrowband networks and 2 MHz were set aside as a guard band to protect against interference. A section of the 700 MHz band plan, showing the location of public safety licenses and the D Block, is provided in Appendix B . 

In the FCC plan for Auction 73, the Public Safety Broadband License (PBSL) was to have been matched with a commercial license of 10 MHz, known as the D Block. The D Block was to be auctioned under rules that would require the creation of a public-private partnership to develop the two 10-MHz assignments as a single broadband network, available to both public safety users and commercial customers. The D Block license was offered for sale in 2008 but did not find a buyer. The FCC then set about the task of writing new rules for a reauction of the D Block.
subsections: section_title: FCC's Announced Plans for the D Block
paragraphs: The FCC subsequently decided to auction the D Block for commercial use with conditions deemed beneficial for public safety users, such as assumption by the license-holder of the cost of developing mobile devices, and guarantees that public safety networks would have roaming and priority access rights to the D Block network. The decision was announced in the National Broadband Plan (NBP), released March 16, 2010. The NBP proposed several actions to be taken to facilitate development of a national wireless broadband network for public safety use. Public safety needs, such as developing standards and establishing procedures, would be addressed through a newly established Emergency Response Interoperability Center (ERIC). 

section_title: Legislation to Assign the D Block to Public Safety
paragraphs: The Broadband for First Responders Act of 2010 ( H.R. 5081 , Representative King) would amend the Communications Act of 1934 by requiring the FCC to allocate the D Block for public safety services. The bill would require the FCC to establish rules to encourage the rapid deployment of an interoperable national wireless broadband network, and to allow public safety license-holders to share spectrum with other entities, as long as requirements for roaming and priority access were met. The First Responders Protection Act of 2010 ( S. 3625 , Lieberman) and the Public Safety Spectrum and Wireless Innovation Act ( S. 3756 , Rockefeller) would require similar rule-making procedures, and requirements.

section_title: Legislation in Support of a Public Safety Network Without the D Block
paragraphs: The discussion draft of the Public Safety Broadband Act of 2010 includes the presumption that the D Block will be auctioned, in that it provides that proceeds from its auction be applied to the construction and operation costs of public safety broadband networks. The draft bill would permit sharing of spectrum designated for broadband networks between public safety and other entities. It would also direct the FCC to allow flexible use of other frequencies in the 700 MHz band designated for public safety. 

section_title: Communications Infrastructure and Governance
paragraphs: The First Responders Protection Act of 2010, the Broadband for First Responders Act of 2010, the Public Safety Spectrum and Wireless Innovation Act, the discussion draft of the Public Safety Broadband Act of 2010, the Next Generation Public Safety Device Act of 2010, and several inter-connected initiatives of the FCC address aspects of how to plan, build, and fund a national network for public safety communications. 
subsections: section_title: Public Safety Broadband Network Requirements
paragraphs: Developments in mobile broadband communications are changing the public safety community's expectations about how to best use the 700 MHz airwaves allocated for their use. Public safety representatives have argued that this spectrum should be used for a wireless network customized to meet needs that they have indentified. Arguments in favor of building a network exclusively for public safety revolve around the shortcomings of current commercial wireless services such as poor availability, inadequate coverage in rural areas, lack of security features, and absence of priority access. 

Network infrastructure requirements for public safety communications that are frequently discussed include

Broadband applications should facilitate emergency response by providing data and images, including video. The network should cover all areas of the United States, ensuring service to meet a public safety emergency anywhere. Broadband services should include voice communications as a back up to mission critical voice channels on other frequencies and offer the same features such as push-to-talk and one-to-one or one-to-many connectivity. Network software should provide traffic management services such as prioritizing service. If multiple networks were built separately and then linked together, interoperability and nationwide roaming would need to be ensured. Radio software should provide mobile broadband applications designed for public safety. In particular, radio chipsets need to be developed for wireless devices that can connect to a Long Term Evolution (LTE) network. Radio software should support encryption and authentication. Cell towers in the network should be strengthened against natural hazards and furnished with back-up power supplies that can outlast extended power outages. Robust backhaul should be ensured. Backhaul typically refers to connectivity between access points like cell towers and high capacity, landline communications networks. Backhaul is an essential component of wireless network infrastructure. 

section_title: FCC's Proposals for Communications Infrastructure
paragraphs: In the NBP, the FCC made these key recommendations for promoting public safety wireless broadband communications.

Create an administrative system that ensures access to sufficient capacity on a day-to-day and emergency basis. Ensure there is a mechanism in place to promote interoperability and operability of the network. Establish a funding mechanism to ensure the network is deployed throughout the United States and has necessary coverage, resiliency, and redundancy. Conform existing programs to operate with the public safety broadband network.

The FCC has recommended that the public safety community leverage the availability of commercial technologies and networks to assure system-wide capacity and has encouraged partnerships and administrative agreements with commercial operators and others. 
subsections: section_title: Emergency Response Interoperability Center
paragraphs: The FCC would address public safety needs such as developing standards and establishing procedures through the newly established Emergency Response Interoperability Center (ERIC). ERIC was established within the FCC Public Safety and Homeland Security Bureau, in April 2010. It is intended for ERIC to work closely with the Public Safety Communications Research program, jointly managed by the National Institute of Standards and Technology (NIST) and the NTIA, to develop and test the technological solutions needed for public safety broadband communications. The Department of Homeland Security is to participate in the areas of public safety outreach and technical assistance, as well as best practices development, through its Office of Emergency Communications. ERIC has been tasked with implementing standards for national interoperability and developing technical and operational procedures for the public safety wireless broadband network in the 700 MHz band. In the future, ERIC may perform similar functions for other public safety communications systems. 

Within the 700 MHz band, ERIC might use the regulatory powers of the FCC to require the cooperation of commercial wireless operators in establishing roaming rights and access rules between the public safety broadband network and other networks built to use the 700 MHz frequencies. In particular, the FCC's powers to write rules for spectrum license auctions and set service rules for auction winners are to be brought to bear on the winner or winners of licenses in the D Block. and it has anticipated that it will be able to negotiate roaming and priority access across the 700 MHz band. Its authority to enforce access requirements is uncertain, however, and might be successfully challenged in court.

section_title: Requirements for Conditional Build-Outs
paragraphs: Some states and localities have petitioned the FCC to allow them to use frequencies from the 10 MHz assigned to the PSBL for their own public safety networks. Plans would be developed based on local and regional needs, with anticipated funding from sources such as existing programs, partnerships with commercial providers, and federal grants. The FCC has therefore adopted an order to provide the framework for nationwide interoperability and mobile broadband and grant waivers to public safety entities that meet its requirements. Providing an "Interoperability Showing" that includes evidence of funding is among the conditions established by the FCC. Fifteen recipients of conditional waivers had submitted Interoperability Showings by August 17, 2010. Only one, from the San Francisco Bay Area, was accepted for review. The remainder were returned for additional work because not all the required elements had been included. Nonetheless, a review of the submission seems to suggest that the materials for building a cohesive national policy are embedded in these plans. 

ERIC will play a lead role in approving and coordinating the technical aspects of the waiver requests. Technical components of the waiver requests include specifications for system architecture, required applications, and network operations, administration and maintenance. System requirements to support interoperability must include radio access network and core network architectures. Plans for supporting roaming, priority access, Quality of Service (QoS), and security are required. Specifications must be provided regarding the devices planned for use on the network, including information on type (form factor), operational specifications, and spectrum coverage. 

section_title: Legislative Proposals for Communications Infrastructure
paragraphs: The First Responders Protection Act of 2010, the Broadband for First Responders Act of 2010, and the Public Safety Spectrum and Wireless Innovation Act would require the FCC to establish rules for the construction and operation of a wireless public safety broadband network. The requirements would cover interoperability, roaming, priority access, network survivability, and cybersecurity. The FCC would also be required to develop a statement of requirements for standards that would take into account: commercial availability of technologies; licensing terms; adaptability; transmission priority; security; and other considerations, as appropriate. 

The discussion draft of the Public Safety Broadband Act of 2010 eliminates requirements for roaming privileges but otherwise would make similar requirements. It would direct the FCC to "take all actions necessary" to develop and implement technical standards and rules for a nationwide public safety interoperable broadband network that would include user authentication and encryption. This and other provisions in the bill would support the FCC's regulatory authority to mandate sharing of 700 MHz infrastructure. The FCC would be required to establish "an appropriate rule, or set of rules" to ensure interoperability, taking into account: commercial availability of technologies; licensing terms; adaptability; transmission priority; and security. The Public Safety Spectrum and Wireless Innovation Act also would address the FCC's need to require roaming, but in more limited terms. It would provide that the FCC "may adopt rules, if necessary in the public interest, to improve the ability of public safety networks to roam onto commercial networks and to gain priority access ..." if certain provisions are met.

The First Responders Protection Act of 2010 does not include any provisions that support the FCC's position to mandate that commercial networks provide access for roaming or make other accommodations to public safety users. These provisions will likely be part of separate contractual agreements between public safety network users and commercial network owners as part of negotiations among multiple players.

The First Responders Protection Act of 2010, the Public Safety Spectrum and Wireless Innovation Act, and the discussion draft provide funding mechanisms for construction and operation of the wireless broadband network. Projects eligible for funding that are mentioned in the bills include "construction of a new public safety interoperable broadband network using commercial infrastructure or public safety infrastructure, or both, in the 700 MHz band" and "improvement of the existing commercial networks and construction of new infrastructure to meet public safety requirements...." There is no provision in any of the bills for funds to cover the cost of development and testing of new radio technologies that allow public safety broadband radios to operate on the new networks.

The Public Safety Spectrum and Wireless Innovation Act has a number of additional provisions related to the requirements for network construction. For example, there are several provisions that are intended to assure that rural areas are given equality with urban areas in planning and construction. The bill also would require that interoperability planning include "integration with 9-1-1 call centers." 

section_title: Communications Infrastructure and Radios
paragraphs: Additional development work is needed to advance from the planning stages to testing and deployment of mobile devices that operate on the broadband network. The Next Generation Public Safety Device Act of 2010 would address the issue of developing mobile devices for broadband communications on frequencies assigned for broadband use, and other frequencies, where feasible. One of the constraints in constructing mobile devices is that it becomes increasingly difficult and expensive for radios to operate on multiple bands. 

Public safety officials, commercial network experts, and the FCC are generally in agreement that Long Term Evolution (LTE) technology should be required for the new broadband network.The term profile is generally used in referring to the range of technical specifications needed for mobile devices using LTE technology to operate on a designated network. The primary group coordinating standards-setting for LTE has established four profiles for commercial bands using LTE in the 700 MHZ band: Band 12, Band 13, Band 14, and Band 17. Band 14 includes the D Block and can include the public safety frequencies assigned to broadband and possibly the frequencies assigned to narrowband as well. The LTE profile for Band 14 needs to be modified to support public safety requirements. Part of the challenge for ERIC and network developers participating in the early-build-out program will be to establish a profile for public safety requirements that can be developed in conjunction with the Band 14 profile for the D Block and, possibly, other LTE bands at 700 MHz.
subsections: section_title: FCC Proposals for Radio Development
paragraphs: In addition to cooperation for sharing network resources, the FCC has anticipated that the D Block owner or owners will lead, and fund, the development costs of the air interface that will operate within the band comprised of the Public Safety Broadband License and the D Block. LTE has been specified by the FCC as the network technology for these frequencies. The FCC has also assumed that the other networks at 700 MHz will use LTE or a compatible fourth-generation (4G) technology. 

One of the expectations is that ERIC will be able to guide the development of standards for crucial radio components, with the participation of commercial providers and public safety representatives. The participation of commercial carriers in developing and deploying, for example, a common radio interface, is expected to put the cost of public safety radios in the same price range as commercial high-end mobile devices ($500). By contrast, interoperable radios for the narrowband networks at 700 MHz cost $3,000 and up, each. 

In a letter responding to an inquiry from Representative Henry A. Waxman, Chairman of the House Committee on Energy and Commerce, the FCC provided a summary of its findings and views regarding market competition for narrowband radios. The general conclusions of the letter were that proprietary technologies had hampered the effective development of public safety radios and curtailed interoperability. 

section_title: Legislative Proposals for Radio Development
paragraphs: The Next Generation Public Safety Device Act of 2010 would require the NTIA, with the agreement of an appropriate working group, to establish requirements for Radio over Internet Protocol Devices (RoIP) and to award grants for the development of these devices. Requirements to compete in the first stage of a three-stage competition include: the identification of specific communication needs of public safety personnel and any corresponding device features that would meet those needs; and ensuring rapid, reliable, comprehensible and interoperable communications. Requirements that must be met in the final stage include submission of a plan for commercial production. In considering the winners at each stage of the process, the NTIA is required to give consideration to additional factors such as encouragement of competition; estimated cost; and the potential to use other portions of the 700 MHz band licensed for public safety use. 

section_title: Funding
paragraphs: At the time of the attempted auction of the D Block, the cost of building the mobile broadband network under the public-private partnership proposed by the FCC was estimated at from $18 billion to as much as $40 billion. These projected costs did not include radios.
subsections: section_title: FCC's Proposals for Funding Infrastructure
paragraphs: In the NBP, the FCC has recommended that a grant program be established to ensure that needed infrastructure is fully deployed. It has recommended that the grants program be administered by a single agency and only be applied to projects that comply with requirements set by ERIC. The four recommended uses of these grants would be: construction of a public safety network, including use of commercial infrastructure; coverage of rural areas; hardening existing commercial networks for public safety use, including reimbursement of non-recoverable engineering costs; and deployable capabilities for public safety. 

The NBP provided an estimate of up to $6.5 billion for capital expenditures over ten years and operating costs of $1.3 billion a year. A subsequent report providing details on these projections were later released. The report included a comparison of costs that concluded that building a dedicated public safety broadband network would require $15.7 billion in capital expenditures. A substantial part of the projected savings would come from the ability for public safety to use commercial towers. 

The NBP stated that it was "essential that the United States establish a long-term, sustainable and adequate funding mechanism to help pay for the operation, maintenance and upgrade of the public safety broadband network." To provide these funds, the plan recommended that a "minimal public safety fee" be assessed on all U.S. broadband users.

section_title: Legislative Proposals for Funding Infrastructure
paragraphs: The Broadband for First Responders Act of 2010 would rely on existing authorizations for funding public safety communications, such as the Interoperable Emergency Communications Grant program. This law authorized appropriations as necessary for FY2008 and appropriations of up to $400 million for fiscal years 2009 though 2012, with such sums as may be necessary in subsequent years. The first appropriations were provided for FY2008 in the amount of $50 million, appropriations in subsequent years have also been for $50 million.

The First Responders Protection Act of 2010, the Public Safety Spectrum and Wireless Innovation Act, and the discussion draft of the Public Safety Broadband Act of 2010 would fund network construction and operation with proceeds from future spectrum auctions. The bills have designated several sets of spectrum bands for auction as sources of revenue over a specified time period. The D Block is included in the draft discussion bill. Two funds would be created to receive auction proceeds. The first $5.5 billion would be destined for a Construction Fund; subsequent proceeds would be administered through a Maintenance and Operation Fund. The NTIA would have primary responsibility for grants programs covered by the funds. Construction projects that would be eligible would be for new construction for a public safety broadband network; improvements to existing commercial networks and other improvements to infrastructure needed to operate an interoperable, public safety broadband network in the 700 MHz band. The bills have described eligibility for reimbursement of maintenance and operational costs and related provisions.

The Next Generation Public Safety Device Act of 2010 would fund the $70 million authorized for RoIP development through revenues generated by future auctions. It would create a Public Safety Devices Communications Fund and authorize the NTIA to borrow the needed funds. The Senate version of the bill would place a ceiling on the amount that could be used to administer the program.
subsections: section_title: Spectrum Auctions as a Source of Funds
paragraphs: Congress has twice enacted laws to create special funds to hold the revenue of certain spectrum auctions for specific purposes. These funds represent a departure from existing practice, which requires that auction proceeds be credited directly to the Treasury as income. The Deficit Reduction Act of 2005 ( P.L. 109-171 , Title III) required the auctioning of licenses for spectrum currently used by TV broadcasters for analog transmissions. It established the Digital Television Transition and Public Safety Fund to receive this auction revenue and use some of the proceeds for the transition to digital television, public safety communications, and other programs. The Commercial Spectrum Enhancement Act ( P.L. 108-494 , Title II) established a Spectrum Relocation Fund to hold the proceeds of certain spectrum auctions for the specific purpose of reimbursing federal entities for the costs of moving to new frequency assignments.

The Public Safety Interoperable Communications (PSIC) grant program, now administered through the Department of Homeland Security, was funded under provisions in the Deficit Reduction Act of 2005.

section_title: Conclusion
paragraphs: Homeland security depends on effective communications for prevention, preparedness, and response to a range of threats. First responders and the larger public safety community that supports them rely heavily on effective radio communications to meet their responsibilities for homeland security. More important to the average American is the role that public safety services play in daily life and in responding to natural disasters. Flash floods, forest fires, tornados, hurricanes—Mother Nature provides endless variations for the scenarios of response and recovery.

The FCC and the Department of Homeland Security (DHS) have different perspectives on radio technology and infrastructure. DHS policies favor reliability and familiarity in their requirements and guidelines for technology and in their emphasis on training and repeated use of equipment. Spectrum policy at the FCC promotes spectrum efficiency and competition among commercial license-holders.

Congress has separately conferred authority on DHS and the FCC to act on behalf of public safety. In the case of DHS, this includes requirements to coordinate and support specific goals, such as interoperability and a national communications capability. None of the actions required of DHS by Congress relate specifically to using 700 MHz spectrum to achieve these objectives. The FCC brings to the process several important mandates from Congress, such as an obligation to "promote safety of life and property through the use of wire and radio communication," as well as specific instructions regarding the assignment of frequencies at 700 MHz. In its National Broadband Plan, the FCC proposed that it assume the needed leadership role and has since taken a number of steps to realize the goals it has set for itself.

The bills introduced so far would increase the powers and responsibilities of the FCC in shaping the public safety communications network of the future, placing DHS in an advisory role. Governance of the public safety network at a national level would be dependent almost entirely on the FCC and its willingness to write and enforce regulations. The Public Safety Broadband Licensee Board of Governors and the Technical Advisory Committee of ERIC appear to be the primary conduits for presenting public safety views and requirements to the FCC. The Public Safety Broadband License, the charter for the Public Safety Broadband Licensee, and ERIC were established by the FCC through its rule-making process.

Since September 11, 2001, Congress has passed several laws that empowered the Department of Homeland Security to recognize and respond to technological developments in wireless and Internet Protocol (IP) communications, and to apply this knowledge to guiding the development of a nationwide, interoperable network for public safety. By choosing to focus on interim solutions, the Department seems to have passed on the opportunity to provide the needed leadership and planning to move public safety toward a next-generation communications network.

It would appear that neither agency has the needed depth of experience or resources to develop and deploy a leading-edge broadband network in a timely, cost-efficient manner. DHS has experience in guiding public safety agencies to meet Department-imposed requirements and guidelines. The FCC has experience in regulating spectrum use by both commercial and state and local (but not federal) public safety sectors. The FCC-created entities that might draw on a broader pool of skills and knowledge are dependent on the long-term, continuing, and unwavering interest of the FCC in maintaining and empowering them. 

A well-grounded but flexible governance structure is critical to the future of public safety communications if it is to be national in scope, interoperable, and cost-effective. In particular, the cost of radios must be brought down to a competitive price range. The latest radios developed for public safety by DHS, the multi-band radios, are estimated to cost between $4,000 to $6,000. The current narrowband radios being used for 700 MHz networks typically start at $3,000. Depending on the area of the country, the cost of ten radios would pay the salary of a teacher, or a teacher's aide. What might be the consequences of a federal policy that forces communities to decide between radios for their police force or teachers for their children, radios to fight fires or funds to maintain parks? Experience with early deployments of narrowband networks appears to indicate that many communities are buying two, four, maybe ten radios to provide for interoperable communications among senior level emergency managers, leaving the rest of their first responder resources to make do with existing equipment that might not work on the new network. At present, federal funds appear to go to build a sort of state-of-the-art wireless highway that only the radio equivalent of Hummers can use.

Several states and urban areas have submitted detailed plans to the FCC for building the nation's first broadband networks that might serve as a practical framework for evaluating policy options. These plans, developed according to FCC requirements, share many common features. Notable from a policy point of view are several recommendations that provide a common theme in these early submissions. These may be summarized as: (1) sufficient funding is essential; (2) networks that either cover an area designated as eligible for Urban Area Security Initiative programs, or cover a regional area—that is, large and/or densely populated areas—are more efficient to build, operate, and govern; (3) several critical technologies and standards, such as for radios, must be developed before the networks can be fully effective; (4) some form of governing sur-structure must be in place to assure uniformity of core operations while allowing for local customization of public safety applications; and (5) collaboration with commercial partners is important for mustering all the skills and knowledge resources needed for developing the leading-edge broadband networks that are the goals of the submitted plans.

A governance structure that can deliver these elements might meet the needs described by many representatives of the public safety community. It does not exist. 

Appendix A. Congressional Efforts on Behalf of Public Safety Communications

Many of the statutes passed since 2001 have provided guidelines and set performance goals for public safety communications while delegating decisions about implementation to federal agencies and state officials. Although Congress has appropriated money for public safety communications it has not directly addressed the question of investment in network infrastructure, leaving it largely to federal agencies to set priorities for how public safety grants can be used. Most of the grant programs are now administered through the Department of Homeland Security (DHS). Grants for emergency communications have been used to purchase equipment that facilitates interoperability, for planning, and for training. 

To facilitate planning and coordination, and to provide direction, Congress authorized the creation of an Office of Emergency Communications (OEC) within DHS. The OEC was given the responsibility of preparing a National Emergency Communications Plan (NECP). The resulting plan set goals for improving emergency communications and interoperability but did not address developing a network infrastructure for public safety communications or for using the 700 MHz spectrum for that purpose. 

To support its vision of interoperability as a system of systems, DHS sponsored an Emergency Response Council (ERC) composed of several dozen agencies, associations, and other entities involved in public safety and emergency response planning. In 2007 the ERC provided a set of agreements on a Nationwide Plan for Interoperable Communications. The ERC published 12 guiding principles deemed essential to their key goals of forging partnerships, designing interoperable systems, educating policymakers, and allocating resources. To date, the council's role has been primarily to establish a base for advocacy and communication among representatives of public safety agencies and associations. 

Congress first addressed the issue of emergency communications interoperability in the Homeland Security Act of 2002 ( P.L. 107-296 ). Two years later, responding to recommendations of the National Commission on Terrorist Attacks Upon the United States (9/11 Commission), Congress included a section in the Intelligence Reform and Terrorism Prevention Act of 2004 ( P.L. 108-458 ) that expanded its requirements for action in improving interoperability and public safety communications. Also in response to a recommendation by the 9/11 Commission, Congress set a firm deadline for the release of radio frequency spectrum needed for public safety radios, as part of the Deficit Reduction Act of 2005 ( P.L. 109-171 ). These laws provided the base from which the Department of Homeland Security (DHS) could develop a national public safety communications capability as required by the Homeland Security Appropriations Act, 2007 ( P.L. 109-295 ). Title VI, Subtitle D of the act, referred to as the 21 st Century Emergency Communications Act of 2006, placed new requirements on DHS. Additional requirements were included in the Implementing Recommendations of the 9/11 Commission Act of 2007 ( P.L. 110-53 ).

Balanced Budget Act of 1997

The initial allocation to public safety of frequencies in the 700 MHz band was required by Congress in the Balanced Budget Act of 1997 ( P.L. 105-33 ), which directed the Federal Communications Commission (FCC) to designate 24 MHz of spectrum capacity for public safety. To carry out the process of assigning this newly allocated spectrum asset, the FCC created the Public Safety National Coordination Committee (NCC) as a Federal Advisory Committee. Active from 1999 through 2003, the NCC had a Steering Committee from government, the public safety community, and the telecommunications industry. The NCC developed technical and operational recommendations for the 700 MHz band, including plans for interoperable channels. The existing governance for these channels is through Regional Planning Committees (RPCs), established and loosely coordinated by the FCC, with the participation of the National Public Safety Telecommunications Council (NPSTC), a group consisting primarily of public safety associations. The RPCs are responsible for submitting 700 MHz band plans to the FCC for approval, and for managing these plans.

The Homeland Security Act of 2002 and Actions by the Department

Provisions of the Homeland Security Act instructed DHS to address some of the issues concerning public safety communications in emergency preparedness and response and in providing critical infrastructure. Telecommunications for first responders is mentioned in several sections, with specific emphasis on technology for interoperability.

The newly created DHS placed responsibility for interoperable communications within the Directorate for Science and Technology, reasoning that the focus of DHS efforts would be on standards and on encouraging research and development for communications technology. Responsibility to coordinate and rationalize federal networks, and to support interoperability, had previously been assigned to the Wireless Public SAFEty Interoperable COMmunications Program—called Project SAFECOM—by the Office of Management and Budget as an e-government initiative. With the support of the George W. Bush Administration, SAFECOM was placed in the Science and Technology directorate and became the lead agency for coordinating federal programs for interoperability. The Secretary of Homeland Security assigned the responsibility of preparing a national strategy for communications interoperability to the Office of Interoperability and Compatibility (OIC), which DHS created, an organizational move that was later ratified by Congress in the Intelligence Reform and Terrorism Prevention Act. SAFECOM continued to operate as an entity within the OIC, which assumed the leadership role. 

Intelligence Reform and Terrorism Prevention Act

Acting on recommendations made by the 9/11 Commission, Congress included several sections regarding improvements in communications capacity—including clarifications to the Homeland Security Act—in the Intelligence Reform and Terrorism Prevention Act ( P.L. 108-458 ).

The Commission's analysis of communications difficulties on September 11, 2001, was summarized in the following recommendation.

Congress should support pending legislation which provides for the expedited and increased assignment of radio spectrum for public safety purposes. Furthermore, high-risk urban areas such as New York City and Washington, D.C., should establish signal corps units to ensure communications connectivity between and among civilian authorities, local first responders, and the National Guard. Federal funding of such units should be given high priority by Congress.

Congress addressed both the context and the specifics of the recommendation for signal corps capabilities. The Intelligence Reform and Terrorism Prevention Act amended the Homeland Security Act to specify that DHS give priority to the rapid establishment of interoperable capacity in urban and other areas determined to be at high risk from terrorist attack. The Secretary of Homeland Security was required to work with the Federal Communications Commission (FCC), the Secretary of Defense, and the appropriate state and local authorities to provide technical guidance, training, and other assistance as appropriate. Minimum capabilities were to be established for "all levels of government agencies," first responders, and others, including the ability to communicate with each other. The act further required the Secretary of Homeland Security to establish at least two trial programs in high-threat areas. The process of development for these programs was to contribute to the creation and implementation of a national model strategic plan. The purpose was to foster interagency communications at all levels of the response effort. Building on the concept of using the Army Signal Corps as a model, the law directed the Secretary to consult with the Secretary of Defense in the development of the test projects, including review of standards, equipment, and protocols.

Congress also raised the bar for performance and accountability, setting program goals for the Department of Homeland Security. Briefly, the goals were to:

Establish a comprehensive, national approach for achieving interoperability; Coordinate with other federal agencies; Develop appropriate minimum capabilities for interoperability; Accelerate development of voluntary standards; Encourage open architecture and commercial products; Assist other agencies with research and development; Prioritize, within DHS, research, development, testing and related programs; Establish coordinated guidance for federal grant programs; Provide technical assistance; and Develop and disseminate best practices.

The act included a requirement that any request for funding from DHS for interoperable communications "for emergency response providers" be accompanied by an Interoperable Communications Plan, approved by the Secretary. Criteria for the plan were also provided in the act.

The act also provided a sense of Congress that the next Congress—the 109 th —should pass legislation supporting the Commission's recommendation to expedite the release of spectrum. This was addressed in the Deficit Reduction Act of 2005 ( P.L. 109-171 ). 

The Homeland Security Appropriations Act, 2007

The destruction caused by Hurricanes Katrina and Rita in August-September 2005 reinforced the recognition of the need for providing interoperable, interchangeable communications systems for public safety and also revealed the potential weaknesses in existing systems to withstand or recover from catastrophic events. Testimony at numerous hearings following the hurricanes suggested that DHS was responding minimally to congressional mandates for action, most notably as expressed in the language of the Intelligence Reform and Terrorism Prevention Act. Bills subsequently introduced in both the House and the Senate proposed strengthening emergency communications leadership and expanding the scope of the efforts for improvement. Some of these proposals were included in Title VI of the Homeland Security Appropriations Act, 2007 ( P.L. 109-295 ). Title VI—the Post-Katrina Emergency Management Reform Act of 2006—reorganized the Federal Emergency Management Agency (FEMA), gave the agency new powers, and clarified its functions and authorities within DHS.

The act also addressed public safety communications in Title VI, Subtitle D—the 21 st Century Emergency Communications Act of 2006. This section created an Office of Emergency Communications (OEC)) and the position of Director, reporting to the Assistant Secretary for Cybersecurity and Communications. The Director was required to take numerous steps to coordinate emergency communications planning, preparedness, and response, particularly at the state and regional level. These efforts were to include coordination with Regional Administrators appointed by the FEMA Administrator to head ten Regional Offices. To assist these efforts, Congress required the creation of Regional Emergency Communications Coordination (RECC) Working Groups.

Other responsibilities assigned to the Director included conducting outreach programs, providing technical assistance, coordinating regional working groups, promoting the development of standard operating procedures and best practices, establishing non-proprietary standards for interoperability, developing a national communications plan, working to assure operability and interoperability of communications systems for emergency response, and reviewing grants. Required elements of the National Emergency Communications Plan included establishing requirements for assessments and reports, and an evaluation of the feasibility of developing a mobile communications capability modeled on the Army Signal Corps. The feasibility study was to be done by DHS on its own or in cooperation with the Department of Defense. Congress also required assessments of emergency communications capabilities, including an inventory that identified radio frequencies used by federal departments and agencies.

Many of the functions Congress envisioned for the OEC were later assumed by the Command, Control and Interoperability Division in the Directorate of Science and Technology.

Regional Emergency Communication Coordination

Congress directed the OEC to coordinate with the Regional Emergency Communication Coordination (RECC) Working Groups established by FEMA. These groups could provide a platform for coordinating emergency communications plans among states and were intended to include representatives from many sectors with responsibility for public safety and security. Plans for forming RECCs were announced in December 2007. In 2008 organization charts were developed, graphing how the RECCs were structured and where they would fit in the existing chain-of-command of the Federal Emergency Management Agency (FEMA). A National RECC Coordinator was appointed and plans were announced to appoint administrators for each of the regions. 

A key proposal for the RECC structure is to "Establish and use the RECC's as a single Federal emergency communications coordination point for Federal interaction with the State, local and tribal governments." It is not clear at this early stage whether the RECCs will become an effective conduit for interaction to develop policies and plan for shared infrastructure or a forum for FEMA's Disaster Operations Directorate to relay guidelines and orders. Congress placed an emphasis on assisting first responders in its statement of RECC goals but did not limit the RECCs' ability to set more inclusive goals. Based on the role of RECCs as assigned by the National Emergency Communications Plan, their focus will be narrowly on assisting first responders to prepare for disaster response. Leadership will be provided by FEMA and governance will be through the chain-of-command of the agencies' directorates.

The formation of the regional working groups, the RECCs, responded in part to requests from the public safety community to expand interoperable communications planning to include the second tier of emergency workers. Non-federal members of the RECC are to include first responders, state and local officials and emergency managers, and public safety answering points (911 call centers). Additionally, RECC working groups are to coordinate with a variety of communications providers (such as wireless carriers and cable operators), hospitals, utilities, emergency evacuation transit services, ambulance services, amateur radio operators, and others as appropriate.

National Emergency Communications Plan

In compliance with requirements of the Homeland Security Appropriations Act, 2007, the Department of Homeland Security issued the National Emergency Communications Plan (NECP) in July 2008. 

The NECP sets three goals for levels of interoperability

By 2010, 90% of all areas designated within the Urban Areas Security Initiative (UASI) will demonstrate response-level emergency communications, as defined in grant programs, within one hour for routine events involving multiple jurisdictions and agencies. By 2011, 75% of non-UASI will have achieved the goal set for UASIs. By 2013, 75% of all jurisdictions will be able to demonstrate response-level emergency communications within three hours for a significant incident as outlined in national planning scenarios.

These jurisdictional goals are to be knit together into a national communications capability through program efforts such as FEMA's Regional Emergency Communications Coordination (RECC) Working Group. The three goals are bolstered by seven objectives for improving emergency communications for first responders, dealing largely with organization and coordination. Each of these objectives have "Supporting Initiatives" and milestones.

Deficit Reduction Act of 2005 and the Public Safety Interoperability Grant Program 

Provisions in the Deficit Reduction Act of 2005 planned for the release of spectrum by February 18, 2009 and created a fund to receive spectrum auction proceeds and disburse designated sums to the Treasury and for other purposes, including a grant program of up to $1 billion for public safety agencies. The fund's disbursements were to be administered by the NTIA. At the time, the Congressional Budget Office projected that the grants program for public safety would receive $100 million in FY2007, $370 million in FY2008, $310 million in FY2009 and $220 million in FY2010. However, the 109 th Congress, in its closing hours, passed a bill with a provision requiring that the grants program receive "no less than" $1 billion to be awarded "no later than" September 30, 2007. Language in Implementing Recommendations of the 9/11 Commission Act of 2007 ( P.L. 110-53 ) required some changes in the grant program and reaffirmed the 2007 fiscal year deadline. 

In February 2007, the NTIA transferred the management of the public safety grant program to DHS, signing a memorandum of understanding (MOU) with the Office of Grants and Training. The MOU included an overview of how the Public Safety Interoperable Communications (PSIC) Grant Program, as it is called, is to be administered. The overview was reiterated and explained in testimony. Both the MOU and the testimony indicate that the priority was to fund needs identified through Tactical Interoperable Communications Plans and Statewide Interoperable Plans developed in conjunction with SAFECOM. 

On July 18, 2007, the Secretaries of Commerce and Homeland Security jointly announced the details of the PSIC grant program. The program, as announced, was to provide $968,385,000 in funding for all 50 states, the District of Columbia, and U.S. Territories. The announcement of the top-level, statewide allocations met the September 30 deadline set by Congress. The states, however, have additional time to submit their detailed requests. Originally, states were eligible to receive funds through FY2010. New legislation ( P.L. 111-96 ) extends the deadline through FY2012. The status of the PSIC grant program was discussed at a hearing in March 2009. Testimony at the time indicated that all of the states, territories, and the District of Columbia had filed Statewide Communication Interoperability Plans, a prerequisite for receiving funds.

Appendix B. Spectrum Chart

Below is an excerpt of the 700 MHz band plan that shows the location of public safety allocations and the D Block, and their relation to other adjacent spectrum holdings.

The figure below represents the relative locations on the spectrum chart of frequencies assigned for public safety and commercial purposes. The accompanying legend provides the key to the type of license and the amount of spectrum associated with that spectrum. For example, reading from the left, the first band represents 11 MHz of the C Block, which is for commercial purposes. The 11-MHz allocation is in two assignments, at 746-757 MHz and at 776-787MHz. The controversial D Block is two assignments of 5 MHz each; these are contiguous with the two assignments for the Public Safety Broadband License.

Note that the figure represents only part of the entire 700 MHz band.

Appendix C. Managing Technology and Spectrum Resources

Within the federal government, the Department of Homeland Security (DHS) has authority for planning and implementing public safety communications solutions. The Federal Communications Commission (FCC) created a Public Safety and Homeland Security Bureau in 2006 to consolidate its many programs oriented toward public safety. The FCC and DHS have each approached the goal of communications interoperability from a different perspective. The following discussion provides snapshot summaries of the approaches adopted by the two agencies and the technologies and network design concepts that might be applied by the FCC. The section also discusses the trend to Internet-based concepts for networks and spectrum management. 

Ideas for managing emergency communications have moved along an evolutionary path from the 1990s, when agreement was reached on developing standards for interoperable communications, to the system-of-systems concept embraced by DHS, to the network-oriented proposals of the FCC, Public Safety Spectrum Trust (PSST), National Public Safety Telecommunications Council (NPSTC), and others. The ubiquity of the Internet and the standards that support it are leading to a new path for managing spectrum and network resources. 

System-of-Systems

The communications solutions advocated by DHS have focused on developing what is often referred to as a "system of systems." The choice of terminology implies that independent systems are made to work with each other through bridges and gateways that connect incompatible technology choices into a larger system. This approach maximizes the value of past investments but does not represent an efficient use of resources. Backward-compatible radio equipment that can support several generations of different technologies, for example, is more expensive than equipment designed to work only with newer network technology. Spectrum usage is inefficient because more than one channel is often used to convey a single communication from system to system. 

Essentially, the system-of-systems concept starts with the radio user and works its way up, adding and connecting the different levels of command and control needed to respond to specific situations. DHS refers to this as a practitioner-driven approach. Many of the DHS programs for public safety have focused on achieving interoperability within the existing framework of proprietary systems and by expanding the diffusion of Project 25, or P25, standards. Backward compatibility with legacy systems is one of the principles behind the digital radio and interoperable gateway standards of P25. Its use is advocated by many public safety agencies and by DHS. P25-compliant technologies coordinate and connect specified radio channels. 

Currently, the Command, Control, and Interoperability Division of the Science and Technology Directorate at DHS is testing and evaluating P25 multi-band radios. The initial phase of the program was announced July 1, 2009. Results will be documented in a report that "will provide details to manufacturers about the needs of the response community and assist officials in making informed radio purchasing decisions in the future." 

Shared Networks

The FCC has taken a more network-oriented approach to achieving interoperability by laying out a plan for a national network at 700 MHz that would eventually reach every community with the same technology and connectivity, providing a common base for individual applications. Network-centric solutions start with the network framework, which sets a common standard. Any traffic that wants to use this network has to accommodate that standard (although it can use additional standards as well). Network-centric solutions tend to be managed from the top down, with centralized control of core decisions. The FCC, primarily through the Emergency Response Interoperability Center (ERIC), is attempting to structure a central administration to lead the decision-making process for implementing a nationwide public safety network. 

Interconnected Networks

The PSST was assigned the Public Safety Broadband License (PSBL) as part of the FCC's plans to create a public-private partnership. The PSST considers that the new broadband network will serve primarily as a data exchange network (text, photos, video, etc.) that would operate as an adjunct to the current mission critical public safety voice systems. Existing voice communications systems and new narrowband systems at 700 MHz would operate independently of the broadband network with an interface to be established in a future development phase. 

The Board of Directors of the PSST received recommendations from NPSTC on how to achieve interoperability among different public safety networks operating in 700 MHz allocations for public safety broadband. These were submitted to the FCC for consideration in December 2009. The recommendations were oriented toward paving the way for the early construction of networks by states and cities. The interoperable framework provided by the task force is based on connecting independent public safety networks. Interoperability would be facilitated by a number of guiding principles and requirements, such as access to the Internet and IP-based voice interoperability gateways. In general, the recommendations of the task force would facilitate these expectations.

Regional (including state and local) broadband systems will operate within the framework of a Nationwide Broadband Data System (NBDS). The NBDS will use Long Term Evolution (LTE) technology and it is assumed that regional systems will as well. Defining minimum requirements for public safety broadband networks at 700 MHz will enable national interoperability. An advisory council will provide governance among individual operators and the PSBL. Public-private partnerships will be allowed. Different scenarios for assignment of the D Block will be accommodated by the Task Force requirements and recommendations. Regional operators will have the right to deploy systems in advance of final requirements and to select and deploy applications beyond what is required. Technical requirements will be specified to facilitate roaming and interoperability. Those that have filed requests to the FCC for permission to build systems will be able to fulfill their 700 MHz broadband objectives as quickly as possible. Best practices for network architecture and configurations will be provided but not required.

Among other recommendations made to the FCC in the same filing, the PSST asked the FCC to authorize it "to establish the technology standard for the 700 MHz nationwide public safety broadband network...."

The Association for Public-Safety Communications Officials—International (APCO) has announced its intention to develop standards for the broadband networks at 700 MHz. Specifically, APCO "will identify gaps and set standards in those areas where none currently exist and where standards are necessary to ensure roaming and interoperability ..." and will "establish basic requirements necessary to ensure interoperability" for the network. APCO is accredited by the American National Standards Institute as a Standards Development Organization. 

IP-Enabled Networks

As part of the discussion about how to bring broadband to public safety users, several organizations recommended Long Term Evolution (LTE), a fourth-generation wireless technology, for the underlying network infrastructure on the 700 MHz frequencies. The FCC has concluded that it will require LTE technology for the network infrastructure for the D Block and the PSBL. Fourth-generation technologies such as LTE are being developed to use Internet Protocol (IP) standards, assuring a high degree of interoperability among other IP-based technologies. Developing standards for public safety interfaces on LTE networks could represent a shift in concept for public safety communications—to IP-based platforms and communications management at the network level. Some public safety representatives have shown a willingness to move from a model that connects disparate systems to a model that provides interoperability through network administration.

Some states have decided to deploy IP-enabled fiber optic networks to support their communications needs, including those of public safety. These networks use IP standards to achieve the same level of interoperability, availability, and flexibility associated with the Internet but do not necessarily link to the Internet. 

Congress has recognized the value of IP-based networks for 911 communications by, for example, requiring the NTIA and the National Highway Traffic Safety Administration to prepare recommendations that would support the transition of out-dated 911 systems to IP-based technologies. Congress has not previously considered giving the same attention to the adoption of IP-based technologies for public safety radio communications.

Adaptive Network Technologies

The FCC, DHS, PSST, and NPSTC approaches to interoperability, although different in perspective, are all based on managing radio channels as the way to meet common goals such as minimizing interference among wireless transmissions.

The concept of channel management dates to the development of the radio telegraph by Guglielmo Marconi and his contemporaries. In the United States, mitigation of radio interference was addressed in what is commonly known as the Radio Act of 1912. Passage of the bill, versions of which had been introduced in earlier Congresses, was prompted in part by Marconi's testimony at a congressional hearing investigating the sinking of the Titanic. The act established the basic principle of assigning licenses for specific channels through a central federal authority, which became the FCC with the passage of the Communications Act of 1934. 

In the age of the Internet, however, channel management is an inefficient way to provide spectrum capacity for mobile broadband. Innovation points to network-centric spectrum management as an effective way to provide spectrum capacity to meet the bandwidth needs of fourth-generation wireless devices. Network-centric technologies organize the transmission of radio signals along the same principle as the Internet. A transmission moves from origination to destination not along a fixed path but by passing from one available node to the next. Pooling resources, one of the concepts that powers the Internet now, is likely to become the dominant principle for spectrum management in the future. 

The new generations of iPhones and Android-based mobile devices provide early examples of how the Internet is likely to change wireless communications as more and more of the underlying network infrastructure is converted to IP-based standards. The devices use Internet protocols to perform many of its functions; these require time and space—spectrum capacity—to operate. 

The core Internet Protocol (TCP/IP) was conceived to work with high capacity landline networks. In a wireless environment, IP applications are bandwidth-intensive, consuming large amounts of channel capacity. Although future generations of mobile broadband devices will no doubt use IP applications that have been refined for the wireless environment, additional capacity will still be required to handle expected increases in activity.

More efficient spectrum use can be realized by integrating adaptive networking technologies, such as dynamic spectrum access (DSA), with IP-based commercial network technologies such as LTE. Radios using DSA chipsets are more effective at managing interference and congestion than the channel management techniques currently in use. If a channel's link fails, the radio is cut off. When radios are networked using DSA, individual communications nodes continue to operate and can compensate for failed links. The effects of interference are manageable rather than catastrophic. The network is used to overcome radio limitations.

Adaptive networking has the potential to organize radio communications to achieve the same kinds of benefits that have been seen to accrue with the transition from proprietary data networks to the Internet. Adaptive technologies are designed to use pooled spectrum resources. Pooling spectrum licenses goes beyond sharing. Licenses are aggregated and specific ownership of channels becomes secondary to the common goal of maximizing network performance. For many, the construction of a new network for public safety communications represents an opportunity to reap the perceived benefits of shared infrastructure and pooled spectrum by using the technologies and principles of network-centric operations.
