COMMUNICATION DEVICE AND RADIO COMMUNICATION SYSTEM COMPRISING THE SAME

Japanese Patent JP2017060156

A

PROBLEM TO BE SOLVED: To provide a communication device and a radio communication system comprising the device that can keep power necessary for communication down even when data transmission speed is accelerated.SOLUTION: A communication device 1 comprises a first communication unit 11, a second communication unit 12, and a control unit 13. The first communication unit 11 performs radio communication with a gateway 2 by first communication method. The second communication unit 12 performs radio communication with the gateway 2 by second communication method with faster transmission speed than the first communication method. The control unit 13 activates the second communication unit 12 when the first communication unit 11 receives an activation request signal from the gateway 2. The control unit 13 establishes a link 32 between the second communication unit 12 and the gateway 2 when the first communication unit 11 receives a connection request signal from the gateway 2 after activation of the second communication unit 12.SELECTED DRAWING: Figure 1
