The project was a study based report on the RAN evolution path of 2.5G EDGE Networks to HSDPA. HSDPA is a 3.5G wireless cellular system, a cost-efficient upgrade to UMTS systems and promises to deliver performance comparable to today’s wireless LAN services, but with the added benefit of mobility and ubiquitous coverage. It can offer data rates of up to 14.4 Mbps which is far beyond what 2.5G and 3G cellular systems could offer. The project focuses on a two-step upgrade, first from GSM towards the deployment of UMTS/WCDMA and then towards HSDPA. It begins a new era of “Mobile broadband” services and faces competition from “WiMAX” – but with GSM services having an obvious upgrade path to WCDMA, HSDPA seems to be leading the market in several parts of the world. HSDPA is an extremely cost-effective path to higher data rates and provides more efficient use of valuable spectrum. It enables operators to compete effectively in increasingly converged markets and satisfy the need for enhanced QoS in an efficient and cost-effective manner.
