Abstract:
A radio system comprising a plurality of transceivers that are arranged to communicate with each other by using a plurality of predetermined radio frequency channels, and means for determining a maximum value for an allowed amount of interference caused to adjacent channels by a transmitter of the transceiver, wherein part of the available radio frequency is allocated to narrowband frequency channels and part to broadband frequency channels and wherein the transceivers of the system are arranged to transmit on different radio frequency channels using different maximum values of allowed adjacent channel interference, and the broadband transceivers of the system are arranged to transmit on the frequency channels on the edges of the frequency range allocated to broadband channels by using a first determined maximum value of adjacent channel interference, and on the frequency channels in the center of the frequency range allocated to broadband channels by using a second determined maximum value of adjacent channel interference, and that these determined maximum values are different.
