Glossary

A Antenna

A device which radiates and/or receives radio signals. When working as a transmitter, it converts high frequency current to electromagnetic waves; when working as a receiver, it coverts electromagnetic waves to high frequency current.

B Baseband

Baseband is a form of modulation in which the information is applied directly onto the physical transmission medium.

BSS

In GSM the Base Station System is a term given to a BSC (Base Station Controller) and the BTS (Base Transceiver Station) associated with it. The number of BTS associated with a BSC is dependent on the manufacturer. Although not mandatory, through interpretation of the Abis interface standard BTS and BSC employed within a BSS will always be supplied by the same manufacturer. The BSS is the physical equipment used to giv e radio coverage to a determined geographical zone called a cell. Functionally, a BSS is subdivided into BSC and BTS.

Base Transceiver Station

A Base Transceiver Station terminates the radio interface. It allows transmission of traffic and signaling across the air interface. The BTS includes the baseband processing, radio equipment, and the antenna.

C Cell

Radio network object that can be uniquely identified by a User Equipment from a (cell) identification that is broadcasted over a geographical area from one UTRAN Access Point. A Cell is either FDD or TDD mode.

Carrier

A sine wave, whose bandwidth is much higher than the bandwidth of a signal and, which can be identified by amplitude, frequency, and phase.

H Handover

The transfer of a user ’s connection from one radio channel to another (can be th e same or different cell).

R Receive diversity

The most common type of diversity, where a mobile device uses two p hysically separate antennas to combine signals from the two antennas to reduce the impact of spatial variations in signal strength and thus increase the average data rate available - sometimes dramatically.

T TMA TRX

A Tower Mounted Amplifier (TMA) is a lower noise amplifier installed close to the antenna. A transmitter and receiver housed together in a single unit and having some circuits in common, often for portable or mobile use.
