Wireless local loop (WLL), is the use of a wireless communications link as the "last mile / first mile" connection for delivering plain old telephone service (POTS) or Internet access (marketed under the term "broadband") to telecommunications customers. Various types of WLL systems and technologies exist. Other terms for this type of access include Broadband Wireless Access (BWA), Radio In The Loop (RITL), Fixed-Radio Access (FRA), Fixed Wireless Access (FWA) and Metro Wireless (MW). == Definition of fixed wireless service == Fixed Wireless Terminal (FWT) units differ from conventional mobile terminal units operating within cellular networks – such as GSM – in that a fixed wireless terminal or desk phone will be limited to an almost permanent location with almost no roaming abilities. WLL and FWT are generic terms for radio based telecommunications technologies and the respective devices which can be implemented using a number of different wireless and radio technologies. Wireless local loop services are segmented into a number of broad market and deployment groups. Services are split between licensed – commonly used by carriers and Telcos – and unlicensed services more commonly deployed by home users and Wireless ISPs (WISPs). 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「wireless local loop」の詳細全文を読む スポンサード リンク
