PROBLEM TO BE SOLVED: To provide a cell radio system capable of solving communication failure due to reflection and shield of a radio wave caused by interference from an external radio apparatus and surrounding physical environment.SOLUTION: With a radio cell system, a cell controller is disposed for the cell to detect a state of the cell and communicates to a battery controller about the state of the cell detected by the cell controller. With communication by radio, a beacon is transmitted from the battery controller to the cell controller to specify a period for radio environmental measurement and a frequency to be measured as conditions. After measuring radio environment under specified conditions, the cell controller returns measurement results with the state of the cell to the battery controller.SELECTED DRAWING: Figure 1 |
