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 Britecell Plus brief Description

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 400 MHz- 2500 MHz

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 (TFAxxx), 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 TFAxxx.
