ABSTRACT:
There is provided a method and an arrangement for flexible coexistence of several radio communication systems on a common radio frequency band. The radio frequency band has a larger bandwidth than the communication frequency band of the several radio communication systems. Prior to the start of a radio communication, the radio frequency band is scanned by a radio transceiver unit of a system for the detection of the presence of interference. The transceiver units are arranged to establish communication over any idle part of the radio frequency band comprising or covering the communication frequency band, thereby avoiding the need for frequency or channel planning. The invention can be used in Personal Communication Systems (PCS) or Cordless Terminal Mobility (CTM) services and Radio in the Local Loop (RLL) applications.
