Commercial carriers want clear spectrum, rather than sharing it with Federal government users. That was the essence of the first of several recommendations in an outline document on spectrum sharing that was considered during the November 11 meeting of the Commerce Representatives on the Commerce Spectrum Management Advisory Committee (CSMAC). While carriers prefer reallocation and clearing of spectrum, the outline also recommended sharing should be studied in spectrum bands that cannot be fully cleared in order to determine what impact those federal systems that remain in the band would have on future commercial uses, and what sharing conditions are required to protect incumbent systems. The outline recommended that joint-studies between incumbents and new entrants be conducted to characterize incumbent operations and evaluate compatibility between new entrants and incumbent Federal government operations. Further, the outline recommended the establishment of a joint government-industry technical committee to conduct the studies.
UTC is working with CSMAC to develop opportunities for utilities and other critical infrastructure industries (CII) to share spectrum with Federal government users. Given carriers' preference for cleared spectrum, utilities may have a better opportunity to share spectrum that cannot be cleared. UTC has advocated for shared access to the 1800-1830 MHz band, which is part of the larger 1755-1850 MHz band that the CSMAC is currently evaluating for broadband use. During today’s CSMAC meeting, the “Search for 500 MHz Working Group” recommended reallocating the entire 1755-1850 MHz band for commercial broadband using a two-stage approach by which the 1755-1780 MHz band would be fast-tracked on a "high priority" and the rest of the spectrum from 1780-1850 MHz would be given a "longer term focus" to provide additional time to further develop government reallocation and sharing options and develop pairing options with other spectrum bands. Thus, the CSMAC appears intent on pushing to reallocate and clear the 1800-1830 MHz band for commercial broadband, but the question remains whether incumbent Federal users in the band will agree to move and whether commercial broadband service providers can afford to pay for relocating them. If not, there may still be an opportunity for utilities to share that spectrum with Federal government users.

The National Telecommunications and Information Administration (NTIA) has reportedly announced that it has completed its analysis of the 1755-1850 MHz band for broadband use. According to TR Daily, NTIA plans to finalize the report and make it publicly available "in the coming weeks." While nothing official has been released yet, the report is expected to conclude that the 1755-1780 MHz portion of the band could be made available for commercial broadband, but that suitable spectrum must be identified for relocating incumbent Federal spectrum users first, which could be a long, drawn-out process.

Meanwhile, NTIA's Commerce Spectrum Management Advisory Committee (CSMAC) has scheduled its next meeting for November 10, 2011 at 9:00 am-12:00 pm ET at the US Department of Commerce in Washington, DC. The meeting is open the public and, while a detailed agenda has not been published yet, will review the findings and recommendations of each of CSMAC's four subcommittees: 500 MHz Initiative; Spectrum Sharing; Spectrum Management Improvements; and Unlicensed Spectrum. The CSMAC was established to assist the Commerce Department in its efforts to develop radio frequency policies that will promote new technologies, expand consumer choice and enhance first responder capabilities. It also develops recommendations for improving the federal government's internal spectrum management policies and stimulating more efficient use of the radio spectrum by state and local governments and the private sector. Doug McGinnis, Principal Smart Grid Communications Architect for Exelon Corporation and UTC Smart Networks Council Board of Director, is a representative on CSMAC.

At a meeting of the Commerce Spectrum Management Advisory Committee (CSMAC) in Boulder, Colorado this week, the “Search for 500 MHz” working group (WG) unveiled an interim report that supports reallocating the 1755-1850 MHz band for commercial services. The 1755-1780 MHz portion of the band would be the highest priority for reallocation, while reallocation of the remainder of the spectrum would be a longer term priority designed to allow more time to develop government relocation and sharing arrangements and to allow for the development of options for pairing the spectrum with other frequency bands. The WG also laid out principles for the band that would favor relocating incumbent Federal government operations entirely out of the band, rather than relocating them into the upper portion of the band. These principles would also limit sharing to short or medium term where necessary, and would only permit long-term sharing to cases where relocation of Federal government incumbents is not possible and where commercial operations would continue to have substantial access to the spectrum. Finally, the WG reported that there was no simple answer to quantifying how much interference that would be acceptable for commercial operations that would be using the band. Instead, the WG recommended case-by-case study of the impact of potential interference. In addition, the WG discouraged the Federal government from instituting exclusion zones as a way of coordinating operations, because such exclusion zones would decrease the value of the spectrum at auction.
