A.R. Noerpel, Chang Li, R.A. Ziegler · 2002
A set of radio air interface protocols is described which is intended to operate in the 1920 to 1930 MHz unlicensed PCS (UPCS) frequency band for isochronous operation, intended for voice and data circuit based communications. The Personal Access Communications System-Unlicensed B, or PACS-UB protocol is based on the PACS radio air interface protocol which is to operate in the licensed spectrum between 1850 and 1990 MHz. PACS-UB conforms to the new FCC Part 15, Subpart D, etiquette and is compliant with the rules of the FCC Memorandum Opinion and Order, June 9, 1994. PACS-UB could be used for wireless Centrex, or PBX applications as well as private residential applications. A dual-mode handset could provide private and public access using network intelligence to locate users.
