WLANs with extended communication ranges

The aim of this paper is to quantify the performance gains in terms of transmission ranges for a broad class of the outer and inner channel coding schemes and deployed space-time coding applied to HIPERLAN2 (H2). As such, the H2 PHY layer represents a broad class of OFDM-based W-LAN technologies. This allows a direct translation of obtained results into performance gains for other standards, such as IEEE802.11a. The outer coding class used comprises a broad class of BCH codes. The inner channel code is either a convolutional or turbo code. The space-time codes deployed comprise higher order space-time trellis and space-time block codes. Assuming a given pathloss model, performance gains are quantified in terms of transmission ranges gained for each H2 PHY mode.
