Understanding Wireless 1

Understanding Wireless 1 is a comprehensive course on the world of cellular radio. It is completely up to date, including explanation of the "latest" broadband wireless technology 1XEV-DO.

We start with basic radio concepts, understanding "analog radio" and "digital radio", then cover 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 an examination of 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.
