摘要:
A system and method are provided to intelligently undertake mandated scanning for radar signals prior to operating a particular wireless device in the 5 GHz band. The disclosed systems and methods provide a capability by which wireless devices are enabled to intelligently scan using a 160 MHz signal, or the largest bandwidth that the wireless device has the capacity to occupy. The disclosed scheme makes use of information about the location of the wireless device to determine characteristic of the environment in which the wireless device is operating. Locations of potentially conflicting radar installations, such as at airports and on military installations, are generally “known.” This information is used to compare to a determined geographic location of the wireless device to assess whether full broad bandwidth DFS scanning cane be reasonably undertaken or whether some narrower channel scanning is appropriate for the wireless device based on proximity to radar installations.
