Within TCL, we designed and
built a full blown HiperLAN/2 prototype, from RF to IP Convergence
Layer. We had a special focus on OFDM technology and enhanced QoS
mechanisms in Data Link Control and upper layers. In this context,
we have developed advanced synchronisation, equalisation and
decoding techniques dedicated to 5GHz radio transmission; an
efficient scheduling policy; a dynamic Link Adaptation
mechanism in addition to a real-time ARQ and an IP Convergence
Layer based on traffic contracts and flow classification.
With this laboratory
prototype, we can illustrate the high level of Quality of
Service supported by HiperLAN/2, the only available WLAN standard
(with HiSWANa) capable of achieving this level of performance. We
also demonstrate that there is no technical issue that
