LTE / SAE Overview

 This 3 day custom seminar provides the student with a survey of current and future Wireless Wide Area Networks and their role in a converged all IP telecommunications world. It provides the student with an understanding of the many nuances of competitive Radio Access (RAN) and Core network technologies as well as the Market implications of 3GPP Long Term Evolution (LTE) for new services and global spectrum allocations. While emphasizing 3GPP long Term Evolution (LTE), the course will provide context by reviewing and comparatively describing various protocol approaches of CDMA including MC CDMA (cdma2000 1x, 1xEV-DO Rev 0, A, B) DS CDMA (UMTS, Rel 99-07, HSPA and HSPA +) and evolutionary OFDMA systems (UMB, WiMAX, LTE,). Next, OFDM(A) will be outlined with concepts describing how it overcomes many radio channel impairments and intersymbol interference challenges to offer high data rates in a spectrally efficient manner. Then Long Term Evolution (LTE) as described in recent versions of 3GPP UMTS Rel 8 will be discussed. A Systems Architecture Evolution (SAE) overview followed by PHY, MAC RLC and RRC discussions will round out the topic. To put things in perspective, throughput performance and legacy 3GPP and non 3GPP (802.X) handoff call flows will be covered. Interspersed throughout the seminar will be fresh Market based discussions regarding new services including but not limited to; Push to X, LBS, Mobile TV, Mobile Payments, Surveillance, and Social Networking.
