Performance evaluation of a bandwidth management scheme for a DECT wireless local area network

Abstract

Increasing commercial interest for wireless LAN has boosted relative research effort during the last few years. The IEEE and ETSI have proposed wireless LAN standards [1,2,3] which utilize recent technological advances to provide high bandwidth. However, the investigation of the capabilities of applied wireless technologies to provide LAN services are of both technical and economical interest. This paper proposes a generic architecture and set of functions for DECT [4,5] access to an Ethernet LAN and elaborates a dynamic bandwidth management scheme for the DECT air interface to ensure optimum resource utilisation. The access scheme performance is evaluated with an analytic traffic model which is utilized to calculate parameters such as the average delay and the average number of packets in system queues and with extensive system simulation.
