Method and means for the detection of radar frequency band interferences in a network system having primary and secondary users

摘要

Subject-matter of the invention is a method for the detection of radar signal interference with primary users of radar services within a defined radar signal frequency band that is also used by secondary users, in particular for RLANs in the 5 GHz frequency band. The invention further relates to an information distribution and allocation network system comprising at least one radio local area network (RLAN) as a secondary user. In order to provide for a reliable radar detection without any restrictions as to the data traffic and the available bandwidth, the invention proposes to use a separate radar signal detector for the detection of possible radar interferers. The invention is particularly useful for systems consisting of or comprising RLANs. <IMAGE>
