This section discusses WiFis in depth. For more information, see Appendix B on page 283. 7.9.1 Wireless Network Overview Wireless networks consist of wireless clients, access points and bridges. • A wireless client is a radio connected to a user’s computer. PX7511-B0 User’s Guide...
Page 105 The SSID is the name of the wireless network. It stands for Service Set IDentifier. • If two wireless networks overlap, they should use a different channel. Like radio stations or television channels, each wireless network uses a specific channel, or frequency, to send and receive information. PX7511-B0 User’s Guide...

Preamble is used to signal that data is coming to the receiver. Short and long refer to the length of the synchronization field in a packet. Short preamble increases performance as less time sending preamble means more time for sending data. All IEEE 802.11 compliant wireless adapters support long preamble, but not all support short preamble. PX7511-B0 User’s Guide...

Page 112 If the registrar is already part of a network, it sends the existing information. If not, it generates the SSID and WPA2-PSK randomly. The following figure shows a WPS-enabled client (installed in a notebook computer) connecting to a WPS-enabled access point. PX7511-B0 User’s Guide...
Page 113 When WPS is activated on both, they perform the handshake. In this example, AP1 is the registrar, and Client 1 is the enrollee. The registrar randomly generates the security information to set up the network, since it is unconfigured and has no existing information. PX7511-B0 User’s Guide...
Page 114 In step 3, you add another access point (AP2) to your network. AP2 is out of range of AP1, so you cannot use AP1 for the WPS handshake with the new access point. However, you know that Client 2 supports the registrar function, so you use it to perform the WPS handshake instead. PX7511-B0 User’s Guide...
