	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.

	Wideband DPD Using Agilent SystemVue and Agilent PXI Modular Hardware  Wideband wireless formats such as LTE-Advanced and 802.11ac require extreme linearity, yet exceed 100MHz in bandwidth. Watch this demonstration of the Agilent SystemVue DPD software and Agilent PXI Modular instruments being applied to digital pre-distortion of a power amplifier. 2011年08月05日再生回数 744
	Fast adjacent channel power ratio (ACPR) measurements | N9030A PXA signal analyzer | Agilent  Watch as an Agilent engineer makes a measurement using the Agilent PXA signal analyzer's fast ACPR measurement. This video shows how a correctly set up PXA can make a measurement in 10 ms (including data transfer time), while exhibiting better than the specified -81 dBc dynamic range. The PXA's fast ACP mode is optimized for throughput. For the highest dynamic range, the PXA has an integrated bandwidth method, which has nominally better -88 dBc W-CDMA ACLR dynamic range (with noise correction on). www.agilent.com 2011年12月16日再生回数 188
