Abstract

The present invention provides a wireless LAN system which allows each slave communication device to perform wireless telephone communication by itself through a host station without relaying through a master communication device while a single wireless telephone line is used, and does not require particular processing such as authentication on the host station side. Each transmission/reception means 5 is controlled to switch between a first state in normal times in which a transmission/reception means 5 of a master communication device 1 is turned on and transmission/reception means 5 of respective slave communication devices 2 are turned off and a second state at the time of control delegation in which, in association with occurrence of a control delegation reason to any slave communication device, the transmission/reception means 5 of the master communication device 1 is turned off and only the transmission/reception means of the predetermined one slave communication device of the respective slave communication devices is turned on, and when a control delegation reason to any slave communication device occurs in the first state, a control delegation signal for permitting the transmission/reception means of that slave communication device to be turned on is transmitted from the master communication device 1 to that slave communication device through the respective short-range wireless communication means 4 to perform switching to the second state.
