Subnet Mask

An address code mask that determines the size of the network. An IP subnet are determined by performing a

BIT-wise AND operation between the IP address and the subnet mask. By changing the subnet mask, you

can change the scope and size of a network.

Subnetwork or Subnet

Found in larger networks, these smaller networks are used to simplify addressing between numerous

computers. Subnets connect to the central network through a router, hub or gateway. Each individual wireless

LAN will probably use the same subnet for all the local computers it talks to.

Super A

Super A is an Atheros proprietary turbo mode to increase speed over standard 802.11a mode. It adds Bursting

and Compression to increase the speed. If you live in countries that prohibit the channel binding technology

(i.e. Europe), you should choose “Super-A without Turbo) if you need more speed than 11a mode

TCP

A layer-4 protocol used along with the IP to send data between computers over the Internet. While IP takes

care of handling the actual delivery of the data, TCP takes care of keeping track of the packets that a

message is divided into for efficient routing through the Internet.

Turbo A

Turbo A is an Atheros proprietary turbo mode to increase speed over standard 802.11a mode. It uses channel

binding technology to increase speed. There are 2 types of Turbo A modes: Dynamic Turbo and Static Turbo.

In Dynamic Turbo, the channel binding will be used only if necessary. In Static Turbo, the channel binding is

always on. This protocol may be combined with Super-A model to increase the performance even more. The

used of channel binding might be prohibited in EU countries.

TX Output Power

Transmit Output Power. The TX output power means the transmission output power of the radio. Normally, the

TX output power level limit for 2.4GHz 11g/b is 20dBm at the antenna end. The output power limit for 5GHz

802.11a is 30dBm at the antenna end.

UDP (User Datagram Protocol)

A layer-4 network protocol for transmitting data which does not require acknowledgement from the recipient of

the data.
