Wireless ATM for broadband multimedia wireless access: The ATMmobil project

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.
