GENERAL INFORMATION
1. Installation & safety requirements
1.1. Environmental conditions:
This equipment is designed for indoor use.
Operating temperature: +5 to +40°C
Do not install in corrosive atmosphere or in critical environmental conditions such as hazardous
classified areas (see appendix G).
1.2. Installation site features
The local unit should be installed in a dry and suitable location where:
• No explosion risks are present;
• The environment is not classified as high-risk in case of fire;
• Suspended particles are not in great concentration;
• The environment is not subject to any traffic which could cause crash damages;
• The site is properly located with respect to the ergonomic positioning of the working environments;
• The system is placed in a private room, protected against any possible violation;
• The system must not be exposed to ultra-violet rays;
• The site must be accessible by maintenance personnel;
• The site must be dry, with low humidity;
• The site must guarantee proper space for cables and natural ventilation to the system;
• A two meter separation from any heating opening is kept.
The remote units should be mounted in reasonable locations as well:
• Do not install inside heating or conditioning units;
• Do not install inside cable pipeline, fire-prevention site, fire escape, lift tunnels, emergency exits, which have to
guarantee defined safety standards;
• Remember that the temperature in the upper part of a room is higher than at 2 meters height. For false ceiling
installation, verify that the environment temperatures do not exceed allowed limits;
• The remote unit transmits the RF signal and safety distance for RF radiation must be respected;
• The units must be accessible for tests and maintenance.
1.3. Connection to the power
The connection to the power has to be carried out using the following precautions:
• It must be properly made according to the due diligence rules (IEC rules, etc.);
• In accordance with the rules for the safety against direct or indirect contacts;
• In accordance with the rules for the safety against the over current (short circuit, overloading);
• In accordance with the rules for the safety against over tension;
• The connection is to be carried out by proper and competent staff.
1.4. Safety and precautions during the installation
The following means and tools will be needed for installation:
• Typical electrician tools: cross-point screwdriver, scissors, pliers, nippers, drill and bits, screw for fixing local
and remote units to the wall.
• Typical means: Proper ladder, scaffolding or air platform for ceiling installation of remote units.
• Caution should be used when installing at a height upper than 2 meters. Personnel who are installing this
equipment should be informed about the possible risks and safety measures when elevated.
1.5. Safety and precautions for lasers
The laser used in BriteCell contains an optical transmitter, which has a power level that is not
dangerous to a person's health. However, it is classified as class III A or Class 1 (European norm
EN60825) equipment. Nevertheless, it is prudent in the installation phase to observe the
following rules:
ü Never look directly at the internal optic connector of the transmitter apparatus when it is switched on. The
wavelength of the laser is not visible to the human eye, which means that long-term damage will not immediately
be known.
ü When working with the optical connectors, verify at each end that both transmitting lasers are switched off.

1.6. Connector care and cleaning
Connectors for single mode optical fibre are designed for sub micron tolerances. Such a
connector has an optical section of only 9 µm diameter. The optical connector is a high
precision device. It must be handled with care, to avoid scratches and other mechanical/optical
damages that will impair or reduce the system’s performanc e
The following rules must be carefully followed:
ü Do not leave optical connectors open, as they will attract dirt.
ü Do not touch the connector tip. Clean it with a proper tissue before inserting it into the sleeve.
ü Use pure ethyl alcohol for improved cleaning.
ü Sleeves may be cleaned by injecting pure gas under pressure.
ü Do not attempt to insert connectors mechanically incompatible. This will result in severe damage.

3. Health and safety warnings
Specialized Mobile Radio (Part 90):
Antenna installation must conform within the following guidelines to meet FCC RF exposure
limits, otherwise an environmental evaluation is required if:
Broadband PCS (subpart E):
Non building mounted antennas: Height above ground level to lowest point of antenna < 10m
Building-mounted antennas: Total power all channels>2000W ERP (3280W EIRP)
Narrowband PCS (subpart D):
Non-building-mounted antennas: Height above ground level to lowest point of antenna < 10m
Building-mounted antennas: Total power of all channels > 1000 W ERP (1640 W EIRP).
Cellular Radiotelephone Service
(Part 22, subpart H):
Non-building-mounted antennas: Height above ground level to lowest point of antenna < 10m
Building-mounted antennas: Total power of all channels > 1000 W ERP (1640 W EIRP).
Paging and Radiotelephone
Service (Part 22, subpart E):
Non-building-mounted antennas: Height above ground level to lowest point of antenna < 10m
Building-mounted antennas: Total power of all channels > 1000 W ERP (1640 W EIRP).
Private Land Mobile Radio\

(3280 W EIRP)
Radio (Part 24) and total power of all channels > 1000 W ERP
(1640 W EIRP).
Radio (Part 22) and total power of all channels > 1000 W ERP
(1640 W EIRP).
Radio (Part 22) and total power of all channels > 1000 W ERP
(1640 W EIRP).
Non-building-mounted antennas: Height above ground level to lowest point of antenna < 10m

IMPORTANT NOTE: To comply with FCC RF exposure compliance requirements, the following
antenna installation and device operating configurations must be satisfied: A separation
distance of at least 20 cm must be maintained between the antenna of this device and all
persons. RF exposure compliance may need to be addressed at the time of licensing, as
required by the responsible FCC Bureau(s), including antenna co-location requirements of
1.1307(b)(3). Maximum permissible antenna gain is:
for the BCR-BCEL FAST719 is 15.4 dB i. (Version TFAF731xx, TFLF734xx)
for the BCR-BCEL-FAST819 is 11.5 dBi. (Version TFAF23xx, TFLF23xx)

BRITECELL FAST
4. System description
BRITECELL™ FAST is a plug and play fibre optic distributed antenna kit, offering the most
suitable solution for indoor coverage in small areas. The package includes up to four compact
RF remote transceivers (TFAF), driven by one local distribution unit (TFLF). It is available in
various frequency ranges (from 800MHz up to 2200 MHz) satisfy the requirements of 2
generation mobile networks for simple coverage needs.
The TFLF local unit has been properly designed into a stand-alone mechanical case, including
all required ancillary and support functions. The kit includes up to four standard TFAF remote
units and a composite fiber-copper cable to connect them to the local unit. The installed remote
units can be retained in case of system expansion to a fully modular BriteCell configuration,
both single band or dual band, with a minimum setting effort.

4.3. Functional description
The BriteCell™ Fast system is a fibre optic distribution system for wireless signals. It consists of
a donor unit (TFLF) feeding up to 4 remote units (TFAF) in a star topology. Each remote unit
directly feeds up to two coverage antennas. The connection between the BTS and BriteCell™
FAST system can either be direct or through a repeater via a duplexed N-connector.
Both donor and remote units are powered at –48VDC (telecom supply). Donor and remote units
shall be connected with pre-connectorized composite fibre optic cable (cable with twin optical
fibre and copper wire for remote supply).
The system installation doesn’t require any particular calculation or setting, making it a real
plug-and-play system. Some useful functionalities, software and hardware, simplifies diagnostic
and commissioning:
• Downlink optical power test point
• Uplink adjustable gain setting
• Link diagnostic by means of individual link LEDs
• Downlink ALC (Automatic Level Control)
• Optical AGC (Automatic Gain Control)
