Summary:In a point to multipoint wireless communications system comprising a master station and a plurality of slave stations operating according to a time division multiplex protocol, a noise and interference level is measured associated with each frequency channels at each slave station, in a predetermined timeslot of the time division multiplex protocol. A histogram is generated of the noise and interference level measurements for each slave station for each frequency channel. A noise and interference level estimate is generated for each frequency channel for each slave station as a predetermined percentile of the respective histogram, and a respective single combined noise and interference level estimate is generated for each frequency channel from the estimates. One of the frequency channels is selected for use in subsequent transmission of frames of the time division multiplex protocol on the basis of the respective single combined noise and interference level estimates.
