Sony patents method to manage signal strength in backscatter networks
Sony has filed a patent for a system that controls how devices communicate using backscatter technology. The invention uses quality data from existing signals to decide which device should send the next signal to ensure the connection remains stable.
In the filing’s own words
The present technology relates to a communication control device, a communication control method, and a program that enable appropriate communication of a backscatter signal. A communication control device determines a communication device that plays a first role of transmitting a third wireless signal necessary for a backscatter signal generation device to generate a third backscatter signal on the basis of first reception quality information relating to reception quality of a first backscatter signal generated by the backscatter signal generation device on the basis of a first wireless signal and second reception quality information relating to reception quality of a second backscatter signal generated by the backscatter signal generation device on the basis of a second wireless signal. The present technology can be applied to a wireless communication system.
What exactly they claim (claim 1)
1. A communication control device comprising: a communication control unit configured to determine a communication device that plays a first role of transmitting a third wireless signal necessary for a backscatter signal generation device to generate a third backscatter signal on a basis of first reception quality information relating to reception quality of a first backscatter signal generated by the backscatter signal generation device on a basis of a first wireless signal and second reception quality information relating to reception quality of a second backscatter signal generated by the backscatter signal generation device on a basis of a second wireless signal.
