Abstract

This paper addresses the broadcast capabilities of WiFi systems transmitting to handheld devices. The analysis includes a comparison of different antennas at the access point (AP) in terms of received signal strength indication (RSSI) for different channel conditions and handset orientations. An H.264 AVC encoder and IP packetisation unit is used to broadcast IP video streams to mobile clients. Measurement and simulation results show that body shadowing and handset orientation can seriously degrade the video quality. The use of dual polarized antennas at the AP is shown to enhance range and video performance. A shadowing and depolarisation margin of around 14dB is required to ensure high quality broadcast reception.
