Spectrum Sharing No Slam Dunk, NAB Warns NTIA; APCO Raises Safety Concerns
NAB warned that spectrum sharing often isn’t easy, commenting (see 1901230028) to NTIA on the national spectrum plan, as other groups filed last week despite the federal shutdown. “Widespread successful spectrum sharing involving sensitive information is likely to require…

a third party, trusted by all involved spectrum users, to act as a frequency coordinator,” NAB said. “All spectrum users involved in a sharing arrangement will need to have real-time communication with the trusted third party to provide up-to-the minute information on operating conditions and to facilitate interference reporting.” This third party must also have “enforcement capability to alter the sharing parties’ operating conditions to mitigate or avoid interference, and to shut down interference sources if necessary,” NAB said. The Telecommunications Industry Association said spectrum policies must be predictable, flexible and efficient, protecting those with superior rights. “Good spectrum policy decisions need to be made on a band-by-band basis, depending on the particular propagation characteristics of a band, existing service allocations, and existing incumbent services within a band,” TIA said. “While spectrum sharing approaches and technologies are increasingly becoming available, the existence of either should not, by itself, justify regulatory action to implement a sharing system.” APCO noted that "public safety communications systems are designed for the worst-case, highest-use scenario and therefore may require a much greater surge capacity.” Declare "spectrum is the quickest and most cost-effective way to provide access to broadband services to rural areas that lack access or choice,” the Wireless ISP Association asked. NTIA “should consider the growing socioeconomic benefits of unlicensed spectrum use cases," like Wi-Fi, the Wi-Fi Alliance said. “This includes promoting shared spectrum access among Federal and unlicensed spectrum users.” Satellite operators need long-term access to spectrum, the Satellite Industry Association said. “Due to the long lead time to design, construct, and deploy satellite networks, satellite operators must obtain funding and spectrum rights years in advance of launch.”
