A power system supplies energy, and a communication system meets the demand for information exchange. A BS is the main intermediary between a communication network and a power network. For the communication network, it is an important transfer point for wireless information transmission.
How does a base station work?
As shown in Figure S3 each user accesses a base station, and the BS then allocates a channel to each new user when there is remaining channel capacity. If all of the channel capacity of a BS is occupied, a user cannot access this BS and must instead access another BS that is farther away.
