Wireless Network Glossary-Part1

The wireless network glossary contains explanation or information about common terms
used in wireless networking products. Some of information in this glossary might be
outdated, please use with caution.

802.3ad is an IEEE standard for bonding or aggregating multiple Ethernet ports into one
virtual port (also known as trunking) to increase the bandwidth.

This is the PoE (Power over Ethernet) standard by IEEE committee. 803.af uses 48V
POE standard that can deliver up to 100 meter distance over Ethernet cable.

International standard for wireless networking that operates in the 2.4 GHz frequency band
(2.4 GHz to 2.4835 GHz) and provides a throughput up to 11 Mbps.

802.1d STP
Spanning Tree Protocol. It is an algorithm to prevent network from forming. The STP
protocol allows net work to provide a redundant link in the event of a link failure. It is
advise to turn on this option for multi-link bridge network.

Also known as “Global Roaming”. 802.11d is a standard for use in countries where
systems using other standards in the 802.11 family are not allowed to operate.

The IEEE QoS standard for prioritizing traffic of the VoIP and multimedia applications.
The WMM is based on a subset of the 802.11e.

A standard provides a throughput up to 54 Mbps using OFDM technology. It also
operates in the 2.4 GHz frequency band as 802.11b. 802.11g devices are backward
compatible with 802.11b devices.

The IEEE standard for wireless security. 802.11i standard includes TKIP, CCMP, and
AES encryption to improve wireless security. It is also know as WPA2.

802.1x is a security standard for wired and wireless LANs. In the 802.1x parlance, there are
usually supplicants (client), authenticator (switch or AP), and authentication server (radius
server) in the network. When a supplicants request a service, the authenticator will pass
the request and wait for the authentication server to grant access and register accounting.
The 802.1x is the most widely used method of authentication by WISP.
