speed, and is backward compatible with 10/100Base-TX standard.
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 54 Mbps data transfer rate. The 5 GHz
frequency band is not as crowded as the 2.4 GHz 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.
802.3ad
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.
802.3af
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.
802.11b
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 loop topology. Spanning
tree allows a network design to include spare (redundant) links to provide automatic backup
paths if an active link fails, without the danger of bridge loops, or the need for manual
enabling/disabling of these backup links. Bridge loop must be avoided because of flooding
issue in the network.
