Abstract
This paper describes parameters and options relevant to OSI layers 1 and 2 when designing a broadband radio interface. For each layers, statements are illustrated with the description of possible options for the specification of Hiperlan type 2 standard, such as: the modulation, system parameters, architecture, duplex schemes, interworking with network protocols. Then, it is briefly described which parameters are essentials for the joint optimisation of layers 1 and 2: switching frequency time, turnaround time, mac-pdu, frame duration, collision detection and radio measurements.
Résumé
Cet article décrit les paramètres et options à considérer au niveau des couches 1 et 2 du modèle OSI lors de la définition d’une interface radio large bande. Pour chaque couche, les discussions sont illustrées par la description des choix possibles pour la normalisation du système Hiperlan type 2, notamment: la modulation, les paramètres systèmes, l’architecture, le mode de duplex, l’interfonctionnement avec les protocoles réseaux. Enfin, il est brièvement décrit quels sont les paramètres essentiels à considérer pour l’optimisation commune des couches 1 et 2, soit: le temps de changement de fréquence, le temps de changement de sens de transmission, le PDU-MAC, la durée de trame, la détection de collision et les mesures radios.
