	TERACOM VIDEOTUTORIAL V6: Cellular Radio  Part of V6 Understanding Wireless 1 from Teracom Training Institute www.teracomtraining.com Best of breed telecommunications training - since 1992 May 15 2007 TYPE: Tutorial, DVD URL: www.teracomtraining.com Understanding Wireless 1 begins with basic radio concepts, understanding "analog radio" and "digital radio", then covers fundamentals of mobile communication networks: base stations, cells, handoffs and mobility. With this in place, we go through the first and second generation technologies: AMPS, TDMA, GSM and CDMA, and understand how each works, their strengths and weaknesses and how they relate to each other. In Part 3, we concentrate on data over cellular and 3G, and cover the differences between GPRS, Wideband CDMA or UMTS, cdma2000, 1X, 3X and 1XEV-DO. We review expected throughput in bits/second and which carriers are supporting which technologies. We conclude with applications such as i-mode, SMS, wireless email, web surfing, WAP and XML. This video provides you with a real understanding of how a cellular network operates, the main technologies, the opposing camps championing different systems, and wireless applications.

Application services include wide-area wireless voice telephone, mobile Internet access, video calls and mobile TV, all in a mobile environment. Recent 3G releases, often denoted 3.5G and 3.75G, also provide mobile broadband access of several Mbit/s to smartphones and mobile modems in laptop computers. In December 2007, 190 3G networks were operating in 40 countries and 154 HSDPA networks were operating in 71 countries, according to the Global Mobile Suppliers Association (GSA). In Asia, Europe, Canada and the USA, telecommunication companies use W-CDMA technology with the support of around 100 terminal designs to operate 3G mobile networks. Roll-out of 3G networks was delayed in some countries by the enormous costs of additional spectrum licensing fees. (See Telecoms crash.) The license fees in some European countries were particularly high, bolstered by government auctions of a limited number of licenses and sealed bid auctions, and initial excitement over 3G's potential. The 3G standard is perhaps well ... 2012年02月06日再生回数 513
