Spectrum Regulation: Case of V-Band

Abstract

Radio spectrum which is a scarce resource is a necessity for mobile communication services. World over, the licensed telecommunication service providers are assigned spectrum using different methodologies for their exclusive use. There have been varied approaches for optimally utilizing spectrum, including auction methods for allocation; allowing unused or underutilized spectrum to be traded and/or shared; and complementing licensed spectrum with unlicensed spectrum. The unlicensed spectrum used in a shared mode formed the basis of the success of Wi-Fi networks. Though the licensed and unlicensed spectra have been treated and used very differently, the 60 GHz band (also called as V-band) possesses interesting properties of both and hence forms the basis of this chapter. Specifically, in this chapter, we delve into the following questions:

• How should spectrum be assigned? What type of methodology is appropriate?

• Should assignment and pricing for access be different from backhaul spectrum?

• What are the regulatory issues in V-Band?

However, to borrow the title of a 1985 film starring Emilio Estevez, “That Was Then, This Is Now.” Currently, one of the biggest challenges we face at the Commission is harnessing enough spectrum to accommodate the growing demand for mobile broadband services. The 60 GHz band can play an important role in meeting this challenge. The signals’ short-range propagation and inability to penetrate walls allows for heavy reuse of the spectrum in dense urban areas without causing interference. And critically, the channels are wide; we have previously allocated an enormous 7 GHz of spectrum for unlicensed use. This large, contiguous swath of spectrum between 57 and 64 GHz could enable high data throughput—precisely what is needed for advanced wireless applications.
