Abstract:
A bandwidth optimizer, dynamically operating in connections relating to radio-communications for multi-bearer systems, especially for DECT systems for short-distance transfer of data packets, the optimizer comprising:a first block to which a bit error rate (BER) is fed and which calculates a most likely number (k) of retransmissions, which is required by quality of an air interface; a second block, which receives from the first block said number (k) of retransmissions and computes, on a basis of such number (k), a transmission time including delay for each of a number of bearers; and a third block, which is fed by the second block and which decides an optimal number of bearers to be allocated to a connection and the output of which feeds a device for resources allocations, said optimal number of bearers representing a maximum band to allocate to the connection, depending also on traffic intensity.
