The 4th generation (4G) of wireless technologies promises a much higher air interface data rate (over 100 Mbps) to users. Delivering such high data rates require a very fast and efficient backhaul network. The current T1/E1 backhaul using legacy TDM digital microwave radios cannot support such high data rate at reasonable costs. Therefore 4G broadband networks require all-IP and Ethernet based broadband backhaul solutions.
The course participants will acquire thorough understanding on transmissions of Ethernet packets over microwave radios, how to select the most technically compliant and cost effective IP Layer 2 microwave radio and effective use of adaptive modulation feature, the role of OSI layers in HSDPA/LTE mobile communications backhaul networks, step by step procedure to design end-to-end transmissions network using capacity requirements form set forth by RF and marketing groups. Participant will clearly understand how to plan links to meet 3G HSDPA end to end Jitter and delay requirements.
Pre-Requisite for Participants:
Good knowledge on Microwave or Link Planning on Path Loss or any link planning software tool.
