Abstract
A wireless communication system includes a wireless base station, a plurality of wireless terminals that communicate with the wireless base station using a first communication function, communicate with each other using a second communication function that consumes less power than the first communication function, and are driven by a battery, and a wireless controller. According to the configuration, it is possible to solve problems of the battery replacement cost of the wireless terminals in the system.
Claims13
A wireless communication system comprising:
- a wireless base station;
- a plurality of wireless terminals each of which is driven by a battery;
- a wireless control device configured to control a communication between the wireless base station and the wireless terminals;
- wherein the wireless base station and the wireless terminals are configured to communicate by a first communication function or a second communication function, a power consumption of the second communication function being lower than that of the first communication function,
- wherein the wireless control device determines, from the wireless terminals, a first wireless terminal whose remaining battery capacity is low and a second wireless terminal whose remaining battery capacity is higher than that of the first wireless terminal,
- wherein the wireless control device controls a communication between the wireless base station and the second wireless terminal to be performed by the first communication function, and controls a communication between the first wireless terminal and the second wireless terminal to be performed by the second communication function.
