Management device that registers communication device to wireless network, communication device, intermediate device, and method, program, and integrated circuit for registration of communication device

摘要

A common key is obtained from a management device 101 by operating a bidirectional infrared remote control 105 at a location 105 a via an infrared communication, the management device 101 being connected to a wireless network. The common key is transmitted to an air-conditioner 104 from bidirectional infrared remote control 105 , after carrying the bidirectional infrared remote control 105 to a location 105 b where it is possible that the bidirectional infrared remote control 105 and air-conditioner 104 communicate via the infrared communication.
