This paper presents a system that provides wireless access to an ATM network, using wireless LAN cards available in the market, combining the CIF technology with some extensions that make it able to operate in a wireless
environment. After an introduction to the problems concerning the use of CIF with wireless LANs, an overview
of the proposed system architecture is given. Afterwards,
some of the adopted mechanisms concerning quality of
service are described, namely, dynamic frame length
adjustment and rate control.
