Course Overview
HSPA (High Speed Packet Access) is an evolution step that makes the downlink/uplink channels of WCDMA packet-based for data services. HSDPA (High Speed Downlink Packet Access) and HSUPA (High Speed Uplink Packet Access) offer much higher data rates on the downlink and uplink, theoretically up to 14.0 Mbps in downlink and up to 5.8 Mbps in uplink respectively. HSDPA & HSUPA Radio Planning is a 5-day course focusing on the technical understanding of the HSDPA/HSUPA technology, its impact on the radio coverage and planning guidelines as well as its implication on existing 3G infrastructures. This course provides a detailed description of the layer 1 and layer 2 protocol functionality introduced in UTRAN to support HSDPA/HSUPA (also known as Enhanced DCH, E-DCH). Special focus is on the new Medium Access Control protocol entities (MAC-hs, MAC-e and MAC-es) and on the functionality and coding of new transport- and physical channels. Network Planning & Optimisation aspects of HSPA are also discussed and the impact to the UTRAN architecture is described. HSPA performance characteristics are analysed and compared to those of classical WCDMA, EDGE and other implementations like Flash-OFDM, Mobile Wimax and WCDMA-TDD. The related layer 1 and 2 protocol functions are dealt with in detail. Further on, the HSPA influence on the underlying transmission networks will be discussed and migration scenarios with WCDMA/HSPA will be presented, as well as the future alignment of those two distinct technologies, based on future 3GPP specification.
Key Benefits
