4. SYSTEM DESCRIPTION
Britecell is a low power distribution system designed to provide indoor coverage for
mobile communication networks.
.The whole system is based on the fiberoptic transmission of multiple RF carriers
from an optical donor unit interfacing to the BTSs (TFL) and an optical remote unit
located in remote sites (TFA) near an antenna.
The transmission of the uplink and downlink RF signals is attained by using bi-
directional fiberoptic links. Furthermore it is possible to reach and feed multiple
remote antennas by distributing a number of fiberoptic links in a star configuration.
The system has been designed to make use of the concept of “low power
distributed antenna system” (DAS). The premise of the DAS system is to achieve
good link quality through the use of many lower power radiating points (fed by
TFAs).
The advantage of this system is lower costs and higher reliability. This is possible
because high power amplifiers are both costly and less reliable than low power
devises.
Britecell is very simply and including a built-in AGC. As such it requires a minimum
design, installation and set-up effort, in contrast with a comparable active cable
systems, which require considerable uplink and downlink design and optimisation.
