An ATM based protocol for Wireless LANs
John Porter, Andy Hopper · 1997
This paper presents a solution to the problem of connectivity of portables to an ATM wired network in the local area environment. A compatible ATM approach is used to provide support for multi-media traffic. Spatial re-use of a single frequency with a large number of small cells is used to increase the aggregate throughput. An experimental system based on low-cost fixed ATM switches and software controlled base stations has been developed. 1 Introduction There is a growing demand for mixed-media traffic support in wired networks and this is beginning to extend to the wireless domain. An example of a device requiring wireless multi-media communication is given by [She92]. Current and future local area WLANS either provide no support for multi-service data or use a hybrid scheme based on dividing the available bandwidth into reservation and collision intervals [DEB93] [Kru92]. ATM is considered to reduce the complexity of the network and improve the flexibility while providing end-end c...
