1.1 The Features
Britecell Plus is an innovative platform designed in order to provide an
effective and flexible coverage to a large variety of indoor scenarios.
Thanks to its high modularity, its low power consumption, and its full-
transparency to protocols and modulation formats, Britecell Plus is the perfect
plug&play solution to distribute any wireless standard (including GSM, GPRS,
EDGE, CDMA, WCDMA, and WLAN IEEE 802.11b) to the in-building
environments requiring reliable and interference-free communications, as well
as high traffic capacity and maximum flexibility about future expansions.
These unique features make the Britecell Plus platform suitable also for
applications to critical areas experiencing difficulties in establishing and
keeping phone calls, while its compact design always guarantees a minimum
aesthetic impact.
1.2 Brief Description of Britecell Plus
Britecell Plus is a Distributed Antenna System (DAS) based on the Radio-over-
Fibre (RoF) technology, and capable of carrying wireless mobile signals
through the 800MHz - 2500MHz frequency range regardless of their protocol
and their modulation format.
The system has two basic components, a Master Unit and a Remote Unit. The
Master Unit is made of one or more subracks typically connected to the BTS
(Base Tranceiver Station) through either a repeater (RF interface) or a coaxial
cable.
Each Remote Unit is connected with a dedicated pair of single-mode optical
fibres (one for UL and one for DL) to the Master Unit. These optical fibres work
on 1310 nm wavelenght and provide low losses and almost unlimited
bandwidth, available for future system developments.
Britecell Plus is a modular system whose basic components are:
one Master Unit made of one or more subracks, each providing 12
module slots. Each slot can host either an active or a RF passive device
(chosen among the wide range of Britecell Plus options), in order to
meet the planned design requirements;
a variable number of Remote Units (TFAx), whose function is feeding
the antenna passive network;
a proper number of indoor antennas, suitable to provide radio coverage
to the area. Britecell Plus is fully compatible with any type of indoor
antennas;
the optical cables required to connect the 19” subracks to the TFAx.
