Radio relay system with locally controlled dynamic channel selection and dynamic capacity allocation

Summary and task DOLLAR A Existing radio relay and PMP systems have no automatic channel selection, which is based on the interference situation, but can only set an externally defined channel. These systems can not dynamically change and not carry out the necessary preparatory measurements independently of the selected channel with interference. The change of the channel transfer rate during operation is also not possible. DOLLAR A solution DOLLAR A is introduced, the metrological channel monitoring of one's own and alternative operating channels by the radio terminals under the control of network management and automatically determines a favorable channel by measuring before the establishment of the radio link as well as the currently used FDM / TDM channel during operation, if necessary, by not noticeable switching changed when the current channel is affected by interference or other reasons. While other radio systems in the same frequency band will be considered and the best possible coexistence achieved by targeted interference avoidance of other systems. DOLLAR DOLLAR A benefit A, the invention is essential in order to replace the existing manual channel setting and the centralized radio planning by acting locally in the radio terminals efficient method for increasing the number and density of straightening and PMP radio systems. Thereby contributing to the frequency-economic use of the radio spectrum.
