Dynamic Bandwidth Allocation

· Dynamic Bandwidth Allocation is implemented using Patent air protocol. Any single PE may use flexible baseband bandwidth, using sophisticated a Bandwidth On Demand mechanism, ranging from 64 Kbps up to 2xE1 with a granularity of 64 Kbps.

· Dynamic bandwidth allocation allows for multi service concentration of voice and data over both circuit-switched and packet switched type channels. The concentration is implemented by streamlining the active radio channels to the actual busy channels.

· Bandwidth reservation allows for pre-allocation of air time for sensitive or high priority traffic. By defining minimum and maximum bandwidth values per CPE service, the operator can guarantee as well as limit the bandwidth allocated to the service user. Thus enabling Quality Of Service to a single user without interference to the all other users.

· Depending on erlang capacities of the voice channels and the permitted blocking rate, the system can support user lines from 960 voice channels (without concentration) up to more than 6000 voice channels (@ 0.2 erlang per line and 1% blocking rate) for frequency allocation of 2x28 Mhz.

· WALKair bandwidth can be allocated in a non-symmetrical scheme allowing higher bit rate in one direction and a lower bit rate at the other direction. This feature is specifically useful for Internet and multimedia applications.
