Abstract
Systems and techniques are provided for wireless communication. For example, a process can include measuring a signal strength of a first advertisement beacon from a second device of a second wireless system; comparing the signal strength of the first advertisement beacon to a threshold signal strength; determining a delay period for the second wireless system based on the comparison of the signal strength of the first advertisement beacon to a threshold signal strength; and outputting a second advertisement beacon for transmission based on the determined delay period.
Claims20
A first device of a first wireless system for wireless communications, comprising:
- at least one memory;
- and
- at least one processor coupled to the at least one memory, the at least one processor configured to:
- measure a signal strength of a first advertisement beacon from a second device of a second wireless system;
- compare the signal strength of the first advertisement beacon to a threshold signal strength to determine that the signal strength exceeds the threshold signal strength;
- determine, based on the determination that the signal strength exceeds the threshold signal strength, a delay period for the second wireless system based on an expected amount of time for an energy harvesting device associated with the first wireless system to transmit a response;
- and
- output a second advertisement beacon for transmission based on the determined delay period.
