STP—Spanning Tree Protocol

Standing-Wave Ratio—See SWR.

SWR—Standing-Wave Ratio. A parameter related to the ratio between

forward transmitter power and the reflected power from the antenna

system. As a general guideline, reflected power should not exceed 10%

of the forward power (≈ 2:1 SWR).

TCP—Transmission Control Protocol. A “guaranteed delivery” pro-

tocol used to set up a connection between two devices with acknowl-

edgements (ACK/NACK), and retries if the data is not received

properly. Requires more overhead than UDP (see below) but is some-

times required in mission-critical systems.

Terminal Server—A device that provides a common connection point

for serial terminals (PCs, printers, endpoint devices, etc.) to a Local or

Wide Area Network (LAN/WAN). The terminal converts serial data

from these terminals into Internet Protocol (IP). The entraNET AP con-

tains a built-in terminal server.

Throughput—A measure of the quantity of data sent and the speed with

which it is transferred in a network.

TFTP—Trivial File Transfer Protocol

UDP—User Datagram Protocol. A basic transmission protocol with low

overhead requirements but with no acknowledgement or retry capa-

bility. It is often used for broadcast transmission where acknowledge-

ments are not required, and incomplete messages are discarded by the

receiving station.
