Embodiment 1

[0047] In this embodiment, the user site uses a common omnidirectional antenna, and the AP is configured with a single-beam smart antenna. The single beam formed by the AP can cover the entire surrounding space after B consecutive scans.

[0048] Fig. 3 is a flow chart of Embodiment 1 of the method of the present invention. Referring to FIG. 3, the media access control method supporting smart antennas in this embodiment includes the following steps:

[0049] Step 101, the access point determines the number of user stations currently associated with it and the width of the directional beam used for scanning.

[0050] In actual service implementation, after the association phase of each user station (that is, the process of mapping between the user station and the access point to start the user station to access the network) is completed, the AP can count all registered (that is, all The number N of user stations associated with the access point. As for the directional beam wi...

Abstract

The invention discloses a method and equipment which supports the application of smart antenna media access. The method includes: access point associated with the current set of users and the number of sites used to the directional scanning beam width; access points according to the connection between the number of pre-established user sites, beam width and the best access method then it chooses the best access method for working; access points use the choose method to provide users access. The access points include: smart antenna modules, identified modules, memory modules, processing units and access modules. Use the method or equipment could load adaptively switch to the optimal performance of the current access methods, which can ensure that the entire network users load performance in various business circumstances are better.

Description

technical field [0001] The invention relates to the fields of wireless local area network and smart antenna, in particular to a medium access control method and equipment supporting smart antenna application in the wireless local area network. Background technique [0002] A wireless local area network, as a wireless data network solution, uses wireless signals to connect user sites and access points (Access Point, AP). The access points and user stations in the WLAN generally use omnidirectional antennas, and the coverage of the access points is small under the specified transmission power. [0003] Smart antennas can be regarded as a mechanism that makes full use of space resources for signal quality improvement, interference suppression (or elimination) and adaptive beam adjustment. A significant advantage of the smart antenna is the range extension. When the smart antenna works in the beamforming mode, the beam can make the user station operate farther away from the acc...
