ABSTRACT:
A method and apparatus of combating the problem of interference in master-slave time division duplex indoor wireless networks based on standards, such as the Bluetooth™ standard, is proposed. The method involves a frequency look-ahead scheme in frequency hopping systems, a scheme of monitoring states of master-slave wireless communication links through values recorded in link history counters, and a scheme of scheduling an appropriate slave unit and choosing a suitable packet size to overcome the effect of interfering sources, if any, in the pico-cell.
