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 forming. The STP
protocol allows network to provide a redundant link in the event of a link failure. It is
advice to turn on this option for multi-link bridge network.

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.

802.11g

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
