Patent ID: 8406316

Claim:
An information processing apparatus comprising: a first module including a first narrow band communication unit for performing narrow band communication with a second module, a first broadband communication unit for performing broadband communication with the second module, a first operation control unit for controlling an operation state of the first broadband communication unit according to an operation mode, and a mode switching unit for transmitting, via the first broadband communication unit, a mode switching signal for switching the operation mode from a first operation mode to a second operation mode; and the second module including a second narrow band communication unit for performing narrow band communication with the first module, a second broadband communication unit for performing broadband communication with the first module, and a second operation control unit for controlling an operation state of the second broadband communication unit according to an operation mode, wherein the first operation control unit places the first broadband communication unit in an operation state in the first operation mode, and places the first broadband communication unit in a standby state in the second operation mode, the second operation control unit places the second broadband communication unit in an operation state in the first operation mode, places the second broadband communication unit in a standby state in the second operation mode, transmits a response signal indicating a reception success of the mode switching signal to the first module via the second broadband communication unit in case the mode switching signal is received via the second broadband communication unit, and then places the second broadband communication unit in a standby state, and the first operation control unit places the first broadband communication unit in a standby state in case the response signal is received via the first broadband communication unit.
