Personal wireless communications

Abstract
Summary form only given. Approaches to tetherless personal communications encompass: derivatives from low-power cordless telephones including CT-2 and Phonepoint/Telepoint in the United Kingdom, Europe, and the Far East; Digital European Cordless Telephone (DECT) in Europe, cordless PBXs and Handiphone in Japan, Universal Digital Portable Communications at Bellcore; and ISM-band products being developed; second-generation higher-power digital cellular mobile radio, e.g. Global Standard Mobile in Europe, TIA and CTIA in the United States, and the Japanese Digital Cellular standard (JDC); both low-power wireless local area networks for data and higher-power wide area radio data networks in the United States and Europe; and medium power personal communication networks in the United Kingdom. These approaches are aimed at different specific applications as well as being at different stages of definition, development, and evolution. Other activity includes regulatory initiatives by the FCC in reaction to petitions for spectrum and requests for experimental licences and starting activities in several standards bodies, including TIA, committee T1, CCIR, CCITT, and IEEE.
