access point

(1) Generically, any computer or device in a network that users can gain access to can be called an access point.

(2) In most cases, an access point is a base station in a wireless LAN. Although there are other wireless technologies that use access points, the term generally refers to a Wi-Fi network. Access points (APs) can be stand-alone devices that plug into a router or switch; however, access point functionality is also built into a wireless router, which is widely used in most homes and small offices (see wireless router).

Like a Cellular Phone System
Multiple access points can be deployed in an organization, and users roaming with their mobile devices are handed off from one access point (AP) to another.

AP Name = Service Set Identifier (SSID)
Wi-Fi networks are assigned a name by the user or network administrator. When devices search for Wi-Fi networks, they display the names, called "service set identifiers" (SSIDs), of all the Wi-Fi access points in the vicinity. For more details, see SSID. See virtual access point and wireless LAN.


Access Points
Access points (APs) are similar to cellphone towers, but transmit shorter distances. Their coverage ranges from as little as 50 feet in diameter to as far as 1,000 feet with amplification. Mobile users are automatically handed off from one access point to another as they meander.

The SSID is a 32-character unique identifier attached to the header of packets sent over a wireless network (WLAN) that acts as a password when a mobile device tries to connect to the access point. The SSID differentiates one WLAN from another so all access points and devices attempting to connect to a specific WLAN must use the same SSID.
