Glossary
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 Some of information in this glossary might be outdated, please use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.
802.11a
An IEEE specification for wireless networking that operates in the 5 GHz frequency range (5.15 GHz
to 5.850 GHz) with a maximum of 54Mbps data transfer rate. The 5GHz frequency band is not as
crowded as the 2.4GHz band. In addition, the 802.11a have 12 non-overlapping channels, comparing
to 802.11b/g's 3 non-overlapping channels. This means the possibility to build larger non-interfering
networks. However, the 802.11a deliver shorter distance at the same output power when comparing
to 802.11g.
802.11b
International standard for wireless networking that operates in the 2.4GHz frequency band (2.4 GHz
to 2.4835 GHz) and provides a throughput up to 11 Mbps.
802.11d
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.
802.11e
The IEEE QoS standard for prioritizing traffic of the VoIP and multimedia applications.
The WMM is based on a subset of the 802.11e.
