摘要

个人接入通信系统(personal access communications system, PACS)是美国国家标准协会针对美国1.9 GHz PCS频段制定的通用空中接口标准。PACS采用频分双工技术，经过优化，可支持低移动性户外行人使用和中距离环境中的无线本地环路应用。PACS- unlicensed B (PACS- ub)是使用时分双工技术的PACS版本。PACS-UB针对私人、室内无线PBX应用和无绳电话进行了优化。使用相同的便携式硬件和相同的信令协议支持两种操作模式。

PACS: personal access communications system: an alternative technology for PCS

The personal access communications system (PACS) is an American National Standards Institute common air interface standard developed for the 1.9 GHz PCS band in the United States. The PACS uses frequency division duplexing technology and is optimized to support low-mobility pedestrian outdoor usage and wireless local loop applications in a medium-range environment. PACS-Unlicensed B (PACS-UB) is a version of PACS using time division duplexing. The PACS-UB has been optimized for private, indoor wireless PBX applications and cordless telephony. Both modes of operation are supported using the same portable hardware and the same signaling protocol.

期刊介绍： IEEE Communications Magazine, considered by most to be their most important member benefit, provides timely information on all aspects of communications: monthly feature articles describe technology, systems, services, market trends, development methods, regulatory and policy issues, and significant global events. These articles are complemented by a variety of departments, including: Conference Calendar, Book Reviews, the Global Communications Newsletter, Scanning the Literature, New products and Product Spotlights, Society News, Your Internet Connection, News from JSAC, and the CommuniCrostic puzzle. Articles are tutorial in nature and written in a style comprehensible to readers outside the specialty of the article. Mathematical equations are generally not used (in justified cases up to three simple equations may be allowed with the consent of the Guest Editor. The inclusion of more than three equations requires permission from the Editor-in-Chief).
