Abstract
The examples describe a self-protection feature in components of an authorized shared access system (ASAS). In the ASAS, radio frequency spectrum is shared by different users having different levels of priority when accessing the shared radio frequencies. Higher-tiered user equipment, such as radar systems, generate signals having significantly higher levels of power than the lowest tier user equipment. Exposure to the high power signals may damage the lower-tiered user equipment. The examples describe a lower-tiered access point device and a lower-tiered end user device that participate in the shared access system to communicate over the shared radio frequency spectrum under control of a shared access system manager. In response to a threat of high power signals, the access points and the end user devices are instructed to enter a self-protection mode. The self-protection is enabled by a local switch system within the access point and the end user devices.
