Abstract: Disclosed are a method and an apparatus for the discovery of a sector in a wireless LAN system. A method for the discovery of a sector by an access point (AP) in a wireless LAN system comprises: a step of setting sector beacon intervals in which the AP of the wireless local area network system transmits a sector beacon to any one sector from among a plurality of spatially divided sectors, and an omni beacon interval in which the AP transmits an omnidirectional beacon to the one sector; a step of transmitting a sector beacon to any one current sector from among the plurality of sectors; a step of transmitting, to the current sector, a transmission frame indicating a sector transmission or a transmission frame indicating an omnidirectional transmission in the sector interval between the sector beacon intervals; and a step of receiving, from the terminal located in the current sector, a response frame indicating that the transmission frame indicating the sector transmission is received and an association is made.

Abstract: An apparatus for adjusting the channel width of a multi-channel fiber amplifier light source, including an erbium-doped optical fiber amplifier constructed to generate a spontaneously emitted, amplified noise beam under a condition that no optical signal is applied thereto, the amplifier being used as a light source for wavelength division multiplexing, namely, a fiber amplifier light source. By the angle-turned Fabry-Perot etalon filter and the fiber-optic beam expander, the channel width can be easily controlled without affecting the free spectral range and the power of output light.

Abstract: The apparatus includes an erbium doped optical fibre amplifier 11 which generates spontaneously emitted, amplified noise beam when no optical signal is applied thereto, a beam expander 40 which increases the cross section of the beam, passes it through free space, and then reduces the cross section, and a second erbium doped optical fibre amplifier 12 which amplifies the output from the beam expander. Optical fibres and couplers 21, 22 couple light from laser diode beam generator 60 into the two optical fibres and optical isolators 31, 32, 33 prevent unwanted oscillation. A Fabry-perot filter 50 is located in the free space in the middle of the beam expander and produces a plurality of wavelength spaced channels which can be used in a wavelength division multiplexing system. The channel width of the system is varied by rotation of the filter without affecting the free spectral range and the power of output light.
