Abstract :
The HIPERLAN type 2 system currently in the final standardisation process in ETSI BRAN is expected to operate in the 5.15-5.35 GHz or 5.47-5.725 GHz or 5.725-5.925 GHz frequency range while the MEDIAN system to be standardised in the near future is expected to work at least in the frequency band from 61.0 to 61.5 GHz allocated to industrial, scientific and medical applications (ISM). Both systems are based on an orthogonal frequency division modulation (OFDM) physical layer scheme and will support quality of service requests for ATM as well as for IP-based networks. Cost-efficient terminal development and broad market acceptance can be supported by designing systems in a compatible and evolutionary way. A renewed MEDIAN system design is presented here, based on experience made in the ACTS project AC006 MEDIAN considering the evolutionary approach regarding recent HIPERLAN type 2/IEEE 802.11a harmonised standardisation actions
