With the rapid development of wireless communication technique, frequency spectrum resource becomes more and more nervous.Especially with wireless local
Net (Wireless Local Area Networks, WLAN) technology, wireless personal area network (Wireless Personal
Area Networks, WPAN) technology development, more and more people wirelessly access internet by these technologies.
These network technologies use unauthorized band operation mostly.Due to the fast development of WLAN, WRAN radio communication service, these
The unauthorized frequency range that network is worked gradually saturation.And other communication service (such as visual broadcast service) needs to lead to
Communication network provides certain protection, makes them from the interference of other communication services.In order to provide good protection, frequency management
The specific mandate frequency range of department specific assigned uses for specific communication service.Compared with authorizing frequency range, unauthorized frequency range
Frequency spectrum resource is many less (most frequency spectrum resource, which is used to do, authorizes frequency range use).And a considerable amount of mandate frequency spectrums
The utilization rate of resource is but very low.Then there have been the facts：The frequency spectrum resource of some parts is relatively fewer but thereon
The portfolio of carrying is very big, and the frequency spectrum resource utilization rate that other has authorized is very low.Therefore, it can be deduced that such knot
