DLC protocols, scheduling, and multiplexing issues for broadband fixed wire
less access networks based on ATM are discussed. The established DSA++ MAC
protocol has been developed at ComNets and has been widely applied within t
he German project ATMmobil. It has been a fundamental contribution to the E
TSI BRAN standardisation of HIPERLAN/2. The DSA++ is here modified to perfo
rm optimal within the fixed wireless access network environment. Therefore,
realistic traffic as well as radio channel models for the respective scena
rios are introduced. Simulation results are presented, showing the feasibil
ity of the respective protocol stack for offering broadband multimedia serv
ices with reasonable quality of service. In addition to this advanced proto
col approach, two systems are discussed which are currently under standardi
sation process. The IEEE 802.16 as well as the European HIPERACCESS systems
are both proposed for fixed wireless access networks. Expected scenarios a
nd applications are presented and basic requirements the standards have to
fulfil are derived. As another aspect of access networks, their impact on t
he global information society is discussed.
