Unlicensed Personal Communications Services

Unlicensed Personal Communications Services or "UPCS" describes the 1920-1930 MHz frequency band allocated by the FCC for short range applications in the United States, such as the Digital Enhanced Cordless Telecommunications wireless protocol. These rules are described in Title 47, Part 15 of the Code of Federal Regulations. Licensed PCS, although not necessarily distinguished as such from UPCS, is used for digital mobile phone services.

DECT devices designed for the U.S., which use the brand name "DECT 6.0", operate in this band.

Prior to an FCC rules change in April 2005, the band also included the frequencies 1910-1930 MHz and 2390-2400 MHz. These were used for a variety of short range communications, including point-to-point microwave links.
