HSDPA/HSUPA Technology

HSDPA (High Speed Downlink Packet Access) and HSUPA (High Speed Uplink Packet Access) are the next big steps in upgrading WCDMA/UMTS networks. These two new radio capabilities enable a new set of packet-based services to go wireless in an efficient way. This training concentrates on the differences that HSDPA/HSUPA has brought to WCDMA radio access. The detailed information about WCDMA radio can be obtained from other courses.

Target audience

The course is intended for anyone, who needs detailed technical information on radio transmission based on WCDMA HSDPA/HSUPA.
