A method and a system for the operation of a geolocation database comprising a spatiotemporal spectrum map comprising of white space spectrum occupancy and/or white space spectrum underutilization data, wherein a) at least one white space spectrum sensor takes measurement data remote from the geolocation database; b) the measurement data are transmitted to the geolocation database; c) the spatio-temporal spectrum map and/or its parameters and/or decisions based on this spectrum map are modified in dependence of the measurements received by the geolocation database.

Method for operating a geolocation database and a geolocation database system

A method for incorporating dynamic orthogonal frequency-division multiplexing ('OFDM') in wireless networks is provided. Information about a wireless channel between a transmitter and one or more receivers communicating according to a wireless protocol is acquired. Dynamic OFDM allocations are generated based on the acquired information about the wireless channel. The dynamic OFDM allocations are transmitted to the one or more receivers according to the wireless protocol.
