MTU
Maximum transmission unit. The size of the largest packet that can be transmitted over a
particular medium. Packets exceeding the MTU value in size are fragmented or segmented,
and then reassembled at the receiving end. If fragmentation is not supported or possible, a
packet that exceeds the MTU value is dropped.
NAT
Network address translation. The capability, defined in RFC 3022, of using one set of reusable
IP addresses for internal traffic on a LAN, and a second set of globally unique IP addresses
for external traffic.
network address translation
See NAT.

Funk Software, Inc.
OFDM
Orthogonal frequency division multiplexing. A modulation technique that sends data across
a number of narrow subcarriers within a specified frequency band. The wireless networking
standards IEEE 802.11a and IEEE 802.11g are based on OFDM.
orthogonal frequency division multiplexing
See OFDM.
pairwise master key
See PMK.
pairwise transient key
See PTK.
PAT
Port address translation. A type of network address translation (NAT) in which each computer
on a LAN is assigned the same IP address, but a different port number. See also NAT.
