Performance Analysis of UMTS/HSPA at the Cellular Level

This paper analyses and compares HSDPA and HSUPA capacity and coverage. For this purpose, a single user model is developed for the estimation of the maximum cell radius, which is then adapted to a multiple users and services scenario. The results from the single user model show that, in an indoor scenario, HSUPA can serve 1.22 Mbps up to 0.19 km, while HSDPA with 10 HS-PDSCH codes can serve 6.0 Mbps up to 0.17 km. In a pedestrian environment, HSUPA can offer 1 Mbps up to 0.7 km, while at the same distance HSDPA can offer almost 3.0 Mbps. The results from the multiple users simulator show an average cell radius of 0.28 km and 0.25 km for HSDPA and HSUPA, respectively. The HSDPA BS throughput is 2.39 Mbps, with an average throughput per user of 0.55 Mbps, while for HSUPA, the BS throughput is 0.62 Mbps with an average user throughput of 0.21 Mbps.
