3.3 Wi-Fi Protected Setup (WPS)
Wi-Fi Protected Setup (WPS) is a standard for easy and secure establishment of a wireless home
network, defined by the Wi-Fi Alliance. The goal of the WPS is to simplify the process of
connecting any home device to the wireless network.
The WPS protocol defines two types of devices in a network:
z
Registrar: A device with the authority to issue the credentials to enroll new clients on the
network. A Registrar may be integrated into an AP, or it may be separate from the AP.
z
Enrollee: A device seeking to join a wireless LAN network.
The WPS gives users a variety of setup options. It uses
PBC
(Push Button Configuration) and
PIN
(Personal Identification Number) to enable user to automatically configure network names
and strong data encryption and authentication.
For the PBC mode, the Access Point and the wireless client just simply push a hardware button or
software button. After pushing Access Point WPS button, the client must push software button
within 2 minutes.
For the PIN mode, input the same PIN number for the Access Point and for the wireless client.
After the connection is made successfully, the wireless client will be able to receive the data from
the Access Point such as SSID, wireless security, and etc.
