The ATMmobil project investigates problems and solutions for wireless acces
s to multimedia services based on ATM. The German Federal Ministry for Educ
ation, Science, Research. and Technology sponsors the project. In contrast
to other wireless ATM projects, the ATMmobil project does not work only on
one specific wireless ATM system. Four different system scenarios are under
investigation, covering the development of local loop, indoor private LAN
and public cellular systems. The objectives and architectures of all four s
ystem scenarios, namely ATM radio in the local loop, wireless ATM LAN, broa
dband cellular ATM access, and integrated broadband mobile systems, are des
cribed in detail. Technical highlights of the four system scenarios and the
relation of the project to the ongoing standardization within ETSI and the
ATM Forum are outlined.
