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..
