HSUPA

( Duration: 2 Days )

HSUPA (High Speed Uplink Packet Access) is a packet-based data service in W-CDMA uplink. HSDPA (High Speed Downlink Packet Access) and HSUPA (High Speed Uplink Packet Access) offer breakthrough data speeds, theoretically up to 14.4 Mbps in downlink and up to 5.8 Mbps in uplink respectively. HSUPA (High Speed Uplink Packet Access) extends the uplink capability, providing peak uplink data rates of 5.76Mbps (up from typically 384kbps maximum in today’s networks) and reduced data latency.

This HSUPA training course provides a comprehensive technical foundation in HSUPA analysis, design, implementation and testing (RF and MAC layers applied to mobile device, Node B (BS) and RNC).

This HSUPA workshop is intended for Radio design engineers, 3G applications developers, radio network planners, system architect and designer, programmers, system engineers, and technical managers.
