摘要： A Base Transceiver Station (BTS) for interworking a Wireless Local Area Network (W-LAN) and a mobile communication network through a Radio-over-Fiber (RoF) link is provided. The BTS having mobile and fixed wireless service distribution functions includes a Wireless Local Area Network Access Point (W-LAN AP), a wireless service function block, a Radio Frequency (RF) converter, and an optical transmitter. The wireless service function block performs transmission/reception to/from a predetermined mobile terminal via a connection for the voice call communication and data communication with an external Base Station Controller (BSC). The RF converter performs a data communication connection with the external BSC, up-converts data from the BSC into W-LAN frequency band data, and down-converts data to the BSC into baseband data. The optical transmitter transmits the up-converted data of the packet data RF converter to the W-LAN AP through a RoF link.
