Original: Windows phone get WiFi BSSID
BSSID, a special Ad-hoc LAN application, also known as basic Service set (BSS), a group of computers that set the same BSS name can be self-formed. Each BSS is given a bssid, which is a 48-bit binary identifier used to identify different BSS. Its main advantage is that it
The faint life is only 5 levels2012-08-02 Bssid is the basic SSID number of your wireless router. It corresponds to an Essid used to implement the wireless bridging function. If there is only one wireless router, you only need to configure a unique bssid number. If you need Wireless bridging, you must configure the Essid to be the same to implement the wireless bridging function. Hope to be useful to you. C

If an AP can support multiple SSIDs at the same time, the AP assigns different bssid to correspond to these SSIDs.BSSID (MAC) 3.

(1) The Wi-Fi network structure mainly includes the following parts:
* The station is the most basic component of the network.
* Basic Service Set (BSS ). The most basic service unit of the network. The simplest service unit can be composed of only two sites, and the site can be dynamically connected to the basic service unit. It is a special application of ad-hoc lan. A group of computers can set the same BSS name to form a group. This BSS name is called bs
