Systems and methods to synchronize wireless devices in the presence of a fmcw radio altimeter

A method for synchronizing a wireless network sharing a radio spectrum with a radio altimeter, the method comprising:

• receiving information regarding a radio altimeter signal;
• in response to receiving the information regarding the radio altimeter signal, allocating a timeslot for a first frequency channel that periodically shares a frequency spectrum with the radio altimeter signal;
• and
• in response to allocating the timeslot, transmitting an arbitrary timing synchronization beacon (ATSB) during the allocated timeslot so that the wireless network and the radio altimeter signal do not concurrently occupy a same channel at a same time and the wireless network is delinked from a period of a frame of timeslots.

A system for synchronizing a wireless network sharing a radio spectrum with a radio altimeter, the system comprising:

• a memory storing instructions;
• and
• a processor executing the instructions to execute a process, the process including:
• receiving information regarding a radio altimeter signal;
• in response to receiving the information regarding the radio altimeter signal, allocating a timeslot for a first frequency channel that periodically shares a frequency spectrum with the radio altimeter signal;
• and
• in response to allocating the timeslot, transmitting, to a plurality of device nodes, an arbitrary timing synchronization beacon (ATSB) during the allocated timeslot so that the wireless network and the radio altimeter signal do not concurrently occupy a same channel at a same time and the wireless network is delinked from a period of a frame of timeslots.

A non-transitory computer-readable medium storing instructions that, when executed by a processor, cause the processor to perform a method for synchronizing a wireless network sharing a radio spectrum with a radio altimeter, the method comprising:

• receiving information regarding a radio altimeter signal;
• in response to receiving the information regarding the radio altimeter signal, allocating a timeslot for a first frequency channel that periodically shares a frequency spectrum with the radio altimeter signal;
• and
• in response to allocating the timeslot, transmitting an arbitrary timing synchronization beacon (ATSB) during the allocated timeslot so that the wireless network and the radio altimeter signal do not concurrently occupy a same channel at a same time and the wireless network is delinked from a period of a frame of timeslots.
