ABSTRACT:
A transceiver used for a wireless in-building communication system has a housing which can be fitted with a luminaire having at least one lamp socket to which AC power supply voltage is supplied. At least one lamp base is projected from the housing and is capable of being engaged with the lamp socket so as to receive the AC power supply voltage from the luminaire. A member for radiating/receiving light or electromagnetic wave is disposed on a surface of the housing or in the housing. A power conversion circuit is disposed in the housing so as to convert the AC power supply voltage received via the lamp base into DC voltage having a predetermined voltage value. At least one transmit-receive circuit is disposed in the housing and is coupled with the radiating/receiving member so as to execute transmit-receive operation. The transmit-receive circuit is operated by the DC voltage supplied from the power conversion circuit.
