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
compatible with 802.11b devices.
802.11h
This IEEE standard define the TPC (transmission power control) and DFS(dynamic
frequency selection) required to operate WiFi devices in 5GHz for EU.
802.11i
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.
802.1Q Tag VLAN
In 802.1Q VLAN, the VLAN information is written into the Ethernet packet itself. Each
packet carries a VLAN ID(called Tag) as it traveled across the network. Therefore, the
VLAN configuration can be configured across multiple switches. In 802.1Q spec, possible
4096 VLAN ID can be created. Although for some devices, they can only view in frames
of 256 ID at a time.
802.1x
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.
