AT&T is pleased to have recently joined into an MOU with our fellow carriers, Verizon and T-Mobile, and the U.S. Department of Defense to test the viability of sharing 95 MHz of spectrum that is currently used by DoD and other federal agencies.  This spectrum is located in the 1755 to 1850 MHz spectrum band, which NTIA has analyzed in great detail for potential clearing and sharing opportunities.

I want to emphasize that we continue to believe that clearing and reallocating is the best approach to freeing up much needed spectrum for commercial mobile broadband use. The existing exclusive licensing regime has resulted in billions of dollars in wireless infrastructure investment, enabling the U.S. to lead the way in the global mobile broadband marketplace.  While clearing spectrum for exclusive commercial licensing must remain the top priority, when that is neither time nor cost effective, AT&T supports exploring sharing arrangements.  As FCC Chairman Genachowski has noted, it doesn’t have to be an either/or choice for effective spectrum management.

Over the next couple months, spectrum monitoring, sharing and simulation activities will be conducted within the band to determine whether existing federal use of this spectrum is negatively impacted by the introduction of commercial mobile broadband services in the band, and conversely how the incumbent DoD system would affect mobile broadband services.  Spectrum will be monitored at five DoD-specified locations.  The actual sharing of spectrum will be evaluated between low power mobile broadband uplinks (base station receivers) and four uses identified by NTIA, including air combat training systems, aeronautical mobile telemetry, satellite command and control, and small unmanned aerial vehicles.

Monitoring and modeling simulation and analysis will wrap up at the end of March and the results will be made publicly available through the Commerce Spectrum Management Advisory Committee (CSMAC).

We look forward to participating in this endeavor and we are hopeful that, by working closely with DoD and other federal users, we are able to identify opportunities to clear spectrum for exclusive licensing and, when that’s not feasible, to develop mutually beneficial sharing arrangements to tackle the ever growing demand for mobile broadband technologies and services.
