If FCC approval is granted, CAI would have the authority to offer consumers in the greater Hartford metropolitan area a variety of services, including high-speed Internet and Intranet access, voice and data transmission, including home shopping and banking, and other interactive services. Recently, CAI and others in the industry have sought and obtained FCC approval for market trials to test the technical and commercial viability of one-way digital transmission-based services. Today's filings seek permanent, unrestricted authority for commercial deployment of both one-way and two-way interactive services. CAI's filings are consistent with the FCC's stated goal of affording spectrum auction winners maximum flexibility to respond to market forces. John Prisco, President and Chief Operating Officer, said, "These FCC filings represent a logical and important step in the evolution of the use of MMDS spectrum.
