Supported Rate Set
The supported rate set defines the transmission rates that are available on this wireless
network. A station may be able to receive data at any of the rates listed in this set. All
stations must be able to receive data at the rates listed in the Basic Rate Set.

TCP
The Transmission Control Protocol (TCP) is built on top of Internet Protocol (IP).
It adds reliable communication (guarantees delivery of data), flow-control,
multiplexing (more than one simultaneous connection), and connection-oriented
transmission (requires the receiver of a packet to acknowledge receipt to the sender).
It also guarantees that packets will be delivered in the same order in which they
were sent.
TCP/IP
The Internet and most local area networks are defined by a group of protocols. The
most important of these is the Transmission Control Protocol over Internet Protocol
(TCP/IP), the de facto standard protocols. TCP/IP was originally developed by
Defense Advanced Research Projects Agency (DARPA, also known as ARPA, an
agency of the US Department of Defense).
Although TCP and IP are two specific protocols, TCP/IP is often used to refer to the
entire protocol suite based upon these, including ICMP, ARP, UDP, and others, as
well as applications that run upon these protocols, such as telnet, FTP, etc.
TKIP
The Temporal Key Integrity Protocol (TKIP) provides an extended 48-bit
initialization vector, per-packet key construction and distribution, a Message
Integrity Code (MIC, sometimes called “Michael”), and a re-keying mechanism. It
uses a RC4 stream cipher to encrypt the frame body and CRC of each 802.11 frame
before transmission. It is an important component of the WPA and 802.11i
security mechanisms.
