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.

Adhoc

A Peer-to-Peer wireless network. An Adhoc wireless network do not use wireless AP or

router as the central hub of the network. Instead, wireless client are connected directly to

each other. The disadvantage of Adhoc network is the lack of wired interface to Internet

connections. It is not recommended for network more than 2 nodes.

Access Point (AP)

The central hub of a wireless LAN network. Access Points have one or more Ethernet ports

that can connect devices (such as Internet connection) for sharing. Multi-function Access

Point can also function as an Ethernet client, wireless bridge, or repeat signals from other

AP. Access Points typically have more wireless functions comparing to wireless routers.
