An ATM cell-switched architecture is utilized in which several ATM Mobile Terminals within a given geographic cell (small cells covering a range of several tens of meters) communicate with an ATM Access Point using radio frequency channels, which is connected to an infrastructure ATM network by the means of conventional ATM links. Mobile Terminals can operate both indoor and outdoor with limited range and have wireless access to the Access Points on the ATM network.Field of SearchUsing time division multiplexingTime division (TDMA) Channel reservation scheme Synchronization Combining or distributing information via time channels Channel assignment Multiple access (e.g., TDMA) Combining or distributing information via time channels Multiple access (e.g., TDMA) Using messages having an address field as header Using time slots Arbitration for access to a channel Adaptive selection of channel assignment technique Transmission time into time slots adjusted based upon propagation delay time | |
