The target of the paper is to study performance of high speed uplink packet access (HSUPA) in indoor environment, applicability of uplink diversity reception for HSUPA, and to provide guidelines for HSUPA coverage planning indoor environment. The single-user measurements show that with the tested antenna configuration without diversity, maximum practical throughput varies between 1.4 and 1.6 Mbps, and it can be achieved when pilot coverage is above -95 dBm. HSUPA was also measured with spatial and polarization diversity reception, and they were noticed to provide about 4.5 dB improvement in uplink reception, providing 20-40 % improvement in HSUPA throughput with pilot coverage below -95 dBm. Diversity reception can provide provide modest gain in system performance, but with planning threshold RSCP > -95 dBm, almost the same performance can be achieved without diversity antennas.
