OMU Optical Master Unit, translates between RF signals and optical signals so that fibre
fed repeaters can be used.
PA Power Amplifier. A device for taking a low or intermediate-level signal and
significantly boosting its power level. A power amplifier is usually the final stage of
amplification in a transmitter.
PSTN Public Switched Telephone Network, standard domestic and commercial phone
service
Radio link The equipment and transmission path (propagation channel) used to carry on
communications. It includes the transmitting system, the propagation channel and
receiving system
Repeater A bi-directional Radio Frequency (RF) amplifier that can amplify and transmit a
received Mobile Station (MS) signal in the MS transmit band. Simultaneously it
amplifies and transmits a received Base Transceiver Station (BTS) RF signal in the
BTS transmit band.

Signal-to-
interference ratio,
S/I
The ratio of power in a signal to the interference power in the channel. The term is
usually applied to lower frequency signals, such as voice waveforms, but can also be
used to describe the carrier wave. See also carrier-to-interference ratio.
Signal-to-noise
ratio, S/N, SNR
The ratio of power in a signal to the noise power in the channel. This term is usually
applied to lower frequency signals, such as voice waveforms. See also carrier-to-
noise ratio

TCH Traffic Channel. A logical channel that allows the transmission of speech or data. In
most second generation systems, the traffic channel can be either full or half-rate
Transceiver A transmitter and receiver contained in one package. A 2-way radio or cell phone is
an example of a transceiver
Transmitter Equipment which feeds the radio signal to an antenna, for transmission. It consists of
active components such as the mixer, driver and PA and passive components such as
the TX filter. Taken together, these components impress a signal onto an RF carrier
