Abstract
The BMBF founded project COVERAGE investigates broadband access to the IP core-net in public or semi-public hot spot scenarios for mobile users. The basis for our investigations are OFDM-systems (Orthogonal Frequency Division Multiplex) like H/2 (HiperLAN/2) or IEEE802.11a which provide data-rates up to 54 Mbit/s. Main topic of COVERAGE are multihop networks as a means to increase the access area of H/2 radio cells. Unfortunately the performance of multihop networks - with respect to throughput - decreases rapidly with the number of so called EPs (Extension Point) as intermediate hop devices. One reason is the protocol overhead of H/2. For single APs this protocol overhead can be accepted, while in a multihop network this overhead is required once for each additional EP. Here we propose a suitable combination of a DLC protocol with sector antennas and SFN (Single Frequency Network) concepts, which reduces the overall protocol overhead.
