摘要： A SW (70) receives an Ethernet® signal from an outside of areas E and F. The SW (70) selects and outputs the obtained Ethernet® signal to any one of APs (91a to 91e) in accordance with a network structure managed by the SW (70). The AP (91a to 91e) converts the Ethernet® signal to an electrical signal type wireless LAN signal, which is in turn output to a main station (10). The main station (10) frequency-multiplexes the signal output from each of the APs (91a to 91e), and converts the signal to an optical signal, which is in turn output to sub-stations (20a and 20b) The sub-station (20a and 20b) transmits the signal transmitted from the main station (10) to a terminal in the form of a wireless radio wave. Thereby, when a plurality of communication areas are present, the accommodation capacity of an AP can be effectively utilized in each communication area.

摘要： A wireless communication system capable of keeping a level of a wireless signal received by a relay apparatus within a predetermined dynamic range. In a control apparatus, a transmitting section converts a downstream electric signal into a downstream optical signal and transmits the downstream optical signal to the relay apparatus via an optical transmission path. The relay apparatus converts the received downstream optical signal into a downstream electric signal and transmits the downstream electric signal as a wireless signal to a wireless communication terminal from a transmitting/receiving antenna section. In the relay apparatus, a level adjustment section adjusts the level of the wireless signal transmitted by the relay apparatus such that the receiving level of the wireless signal received by the relay apparatus is kept within a predetermined range.

摘要： An optical transmitter for performing high-rate data communication by means of optical space transmission is provided, which can reliably perform optical axis adjustment manually and visually, and can prevent a device from being made large in size and manufacturing cost of the device from being increased by using an simply-constructed optical transmitter. Thus, the optical transmitter of the present invention comprises an incident beam restriction section operable to allow only a visible beam which is emitted by a terminal located within a range in which an infrared beam is emitted and incident thereon to pass therethrough, a reflection section operable to reflect the visible beam which has passed through the incident beam restriction section, and a light source operable to emit the infrared beam to pass through the reflection section according to a data transmission request signal from the terminal.
