Product Description


B 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 give 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 the same or different cell).


Product Description


R

Receive diversity

The most common type of diversity, where a mobile device uses two physically 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 A Tower Mounted Amplifier (TMA) is a lower noise amplifier installed close to the antenna.

TRX A transmitter and receiver housed together in a single unit and having some circuits in common, often for portable or mobile use.
