SNR
—Signal-to-Noise Ratio. A measurement of relative received
signal quality. High ratios likely result in better signal detection
and performance.
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”
protocol used to set up a connection between two devices with
acknowledgements (ACK/NACK), and retries if the data is not received
properly. Requires more overhead than UDP (see below) but is
sometimes required in mission-critical systems.
Terminal Server
—A device that provides a common connection point
for serial terminals (PCs, printers, endpoint devices, and so on) to a
Local or Wide Area Network (LAN/WAN). The terminal converts serial
data from these terminals into Internet Protocol (IP). The entraNET AP
contains 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
capability. It is often used for broadcast transmission where
acknowledgements are not required, and incomplete messages are
discarded by the receiving station.
