The Magic WAND-functional overview

摘要

The Magic WAND project (Wireless ATM Network Demonstrator) is onenof the largest projects within the European Union ACTS (AdvancednCommunications Technologies and Services) initiative. The project aimsnto design, verify, implement, and demonstrate a wireless access networknfor ATM LAN's. The complete range of functionality, from physical datantransmission to shared multimedia application, is addressed. The WANDnsystem is designed for indoor environments with user mobility limited tonwalking speed. The system's functional specification has been designednand verified using SDL (specification and description language). In thisnpaper, the WAND system functional model is given and SDL simulationnresults are presented, to illustrate how the protocols support some ofnthe key operations of a wireless access network. These include initialnregistration, call setup, and handover
