2.1. Introduction
Basically, a Britecell system is composed of:
• a Master Unit, able to bring mobile radio signals from the BTS to different
remote units and vice-versa, so as to remotise the distribution and collection
of any mobile and wireless signal;
• a variable number of Remote Units, conveying and receiving mobile signals
by low-power antennas.
We hereby will provide a brief introduction to the main components of the
Master and Remote Units which make up the Britecell system, while further
details about each component will be given in the next sections of the present
manual.
2.2. The Britecell Plus Remote Unit
and its relevant accessories
The Remote Unit (TFAx) is a device providing optical-to-electrical downlink
conversion and electrical-to-optical uplink conversion, thus allowing a
bidirectional transmission of signals between the Master Unit and the remote
antennas. It is available in 3 different power configurations
(Low/Medium/High), housed by 4 different architectures (Case A, Case B, Case
F and Case L), so as to fulfil different coverage and band requirements.
In downlink, each TFAx receives an optical signal from the Master Unit,
performs an optical-to-RF conversion, and transmits the resulting signal to the
2 antenna ports.
In uplink, it receives a RF signal from remote antennas, provides a RF-to-
optical conversion, and conveys the converted signal to the Master Unit
through optical fibres.
