One of the challenges in designing a wireless ATM network is to specify con
trol functions capable of managing data and signaling connections of moving
mobile terminals. The challenge is tough, due to the facts that such contr
ol functions neither exist in the current state-of-the-art wireless network
s nor are included in the existing ATM specifications and implementations.
This article describes the design principles of a wireless ATM signaling st
ack created in the WAND project. The article identifies some common problem
s and presents possible solutions to the problems. To justify the feasibili
ty of the ideas presented, some details of a reference implementation, the
WAND demonstrator signaling stack, will be revealed.
