1. Teko Telecom Modular Coverage and Capacity System - General
Description
Teko Telecom Coverage and Capacity Systems are flexible multi-band multi-operator Systems
that provide a wide range of solutions to extend both indoor and outdoor cellular coverage
in shadow areas -where the RF signal is not available- and to increase capacity in indoor and
outdoor hot spots -where the operators need a dedicated coverage.
Modular design is a key feature of Teko Telecom Coverage and Capacity Systems: it offers
flexible configuration options to build the most suitable solution for any coverage need.
SIRIUS
Stand-alone Modular Repeaters, Optical Systems as well as integrated solutions share a unique
common platform: SIRIUS.
SIRIUS includes a wide range of active and passive components that can be assembled in a
variety of ways in order to provide easy to set-up, maintain, and upgrade products operating
in the 380 to 2700MHz frequency range.
SIRIUS components can be used in different Systems with different functionalities to meet
present needs and to allow system adaptation to changing conditions, always assuring
optimized performances.
Teko Telecom Master Unit is the core of SIRIUS modular design: it is a versatile modular rackbased platform that controls the whole Coverage System and, depending on its components
configuration, is able to provide:
• the RF interface towards the signal source (BTS, Node B, Repeater),
• the RF interface towards Service Antennas/leaky cable,
• the optical interface towards up to 144 Remote Units.
This technical handbook describes the components of SIRIUS and how these components can
be assembled to provide Optical Systems and Modular Off-air Repeaters to improve coverage
in different environments.

1.1 Components
The components of SIRIUS, Teko Telecom Modular Coverage and Capacity System, can be
grouped in the following categories:
1. Modules providing the RF interface towards the signal source
• Point of Interface (POI) module: it is the single-band/single-operator interface towards
a BTS or NodeB. The Point of Interface module is connected to the signal source via
coaxial cable.
• Digital Donor Front End Module: it is the single-band/single-operator interface
towards a Donor Antenna, providing a connection to a BTS or NodeB over an air link.
2. Equipment extending coverage / distributing capacity
• Service Front End: it is the single-band/multi-operator interface towards a Service
Antenna. It provides wireless signal to the area to be covered (Modular Repeaters).
In Optical Systems the Service Front End can be used to extend coverage to the area
close to the Master Unit site.
• Remote Unit: it is the multi-band/multi-operator equipment used in Optical Systems
to distribute wireless signal throughout the area to be covered (extensive areas
coverage/active DAS).
3. Modules providing the optical interface towards Remote Units
• Fiber Optic Transmitter/Receiver Modules are the optical interface between Master
Unit and Remote Units: they provide RF-to-Optical/Optical-to-RF conversion.
• Master and Slave Point to Point Modules perform the RF-to-Optical/Optical-to-RF
conversion required by the optical point to point link connecting RF Interface modules
to distant Fiber Optic Transmitter/Receiver Modules. The optical point to point link
allows a separation distance -up to 20km- between RF Interface modules and Fiber
Optic Transmitter/Receiver Modules.
4. Passive Modules providing distribution and filtering
Due to the flexible configuration options of Teko Telecom Coverage and Capacity Systems,
the same passive components can be used for different purposes.
• The 4-way Combiner/Splitter can be used to manage either up to 4 RF interface
modules, operating in the same band (Multi-Operator Systems) or up to 4 Fiber
Optic Modules (Fiber Optic Transmitter/Receiver Modules or Master Point to Point
Modules).
• The Band Splitter/Combiner (Triplexer) with built-in 1:4 Splitter/Combiner
can be used to manage up to 3 RF interface modules or Service Front End subracks,

• Teko Telecom Digital Donor Front End
The Digital Donor Front End Module is the single-band/single-operator System RF interface
towards a Donor Antenna. No physical connections are required between the DFE and the
cellular network: the Donor Antenna provides the connection to a BTS or NodeB over an air
link.
Coverage Systems can be equipped with one or more Donor Front End modules to make
multiple configurations available: single operator (single band / multi-band) and multioperator (single-band / multi-band).
A single-band single-operator modular Off-air Repeater can be set up combining a Digital
Donor Front End Module and a Service Front End (Teko Telecom single-band/multi-operator
interface towards a Service Antenna). Up to 4 Donor Front End Modules can be connected to
a single Service Front End to provide a single-band 4-operator modular Off-air Repeater.
Digital Donor Front End Modules can also be used to drive Optical Systems: the Digital Donor
Front End Module allows Optical Systems to be driven without the need of a dedicated BTS or
Node B. A donor antenna picks-up the signal and the Optical System acts as a repeater with
distributed Service antennas connected to the Remote Units. Service Front End subracks can
be connected to DFE modules to provide coverage to the area next to the Master Unit site.

www.tekotelecom.it
Each DFE module hosts the duplexer, to be connected to the Donor Antenna to separate/
combine downlink and uplink paths.
In downlink the signal from the Donor Antenna is preamplified by a Low Noise Amplifier and
converted into an IF signal by a downconverter. The selection of the band of frequencies or
channels to be extended is handled by a digital filter.
The digital filter can manage 1 variable band or 2 variable sub-bands.
An upconverter converts the IF signal into the RF output signal.
In uplink the signal from the Service Front End Subrack or from the Optical System is converted
into an IF signal by a downconverter, filtered and re-converted into an RF signal, amplified by
a power amplifier and re-transmitted to the signal source.

• Teko Telecom Remote Units
Remote Units are used in Optical Systems to distribute wireless signals throughout the area
to be covered. They are connected to the Fiber Optic Transmitter/Receiver Modules equipped
in the Master Unit.
Remote Units are equipped with the Fiber Optic Receiver and Transmitter module (for Optical
to RF and RF to Optical conversion), power amplifiers and filtering.
They can be Single, Dual or Tri-band with four different RF power classes: Very High, High,
Medium and Low.
Remote Units with different power classes can be driven simultaneously by the same Master
Unit to distribute capacity or extend coverage into different locations at the same time.
Very High, High and Medium Power Remote Units are equipped in a weatherproof IP66
case. Low Power Remote Units are equipped in an IP32 case; a protection kit, providing IP66
protection degree, is available as option for installation in harsh environments.
Single, Dual or Tri-band Very High, High and
Medium Power Remote Unit

1.1.3 Modules providing the optical interface towards Remote Units
• Fiber Optic Transmitter/Receiver Modules
Fiber Optic Transmitter/Receiver Modules are the optical interface between Master Unit and
Remote Units: they provide RF-to-Optical/Optical-to-RF conversion. They are connected to
Remote Units via single mode optical fibers, with Uplink and Downlink signals transmitted
over the same fibre (Wavelength Division Multiplexing -WDM technology).
Different modules configurations are available: a single Fiber Optic Transmitter/Receiver
Module can be equipped with 1 Optical Transmitter and 1 Optical Receiver (10dB optical link
budget, up to 20km distance - 12.4 miles), or 1 Optical Transmitter split by 2 and 2 combined
Optical Receivers (10dB optical link budget, up to 20km distance- 12.4 miles), or 1 Optical
Transmitter split by 4 and 4 combined Optical Receivers (6dB optical link budget, up to 12km
distance - 7.5 miles).
The Fiber Optic Transmitter/Receiver Module in 1:4 configuration can manage up to 4 Remote
Units.
The Fiber Optic Transmitter/Receiver Module in 1:1 configuration is able to drive up to 5
cascaded Remote Units with different wavelengths in Up-link.
Fiber Optic Transmitter/Receiver Module equipped with 1 Optical Transmitter split by 4 and 4 combined
Optical Receivers
The Fiber Optic Transmitter provides the RF to optical conversion (Downlink side): the module
RF section covers the 380 to 2200MHz band (TTRC models) or the 380 to 2700MHz band

(TTRU models).
Fiber Optic Receivers convert uplink optical signals from Remote Units into RF. They operate
in the third window (Optical wavelength 1490 ÷ 1570 nm).
Each Fiber Optic module is controlled by a microprocessor which provides the following data
to the Supervision Module:
-- optical power received by each optical receiver,
-- Downlink attenuator and Uplink attenuator attenuation setting (0 ÷ 15dB),
-- received optical power alarms.
An auto-levelling functionality (AGC) compensates up to 10dB optical link loss in order
to guarantee constant gain over different optical budgets. This feature simplifies system
installation, makes commissioning quick and easy and avoids field adjustments.

• Master and Slave Point to Point Modules
Master and Slave Point to Point Modules provide an optical point to point link allowing a
separation distance -up to 20km- between RF interface subracks and optical subracks.
The point to point link is suitable when the signal source (BTS, Node B, Repeater) is located
far from the area to be covered or when the same optical system provides coverage to several
separate buildings; in these applications the point to point link allows the transmission of
signals from/to a group of remote units over a single optical fibre, thus providing a significant
reduction in the number of fiber optics running long distances.
The point to point link requires the RF interface subracks to be equipped with Master Point
to Point modules and the remote optical subracks to be equipped with Slave Point to Point
modules. The RF Interface subracks can be equipped with up to 4 Master Pont to Point modules
for the management of up to 4 optical subracks, installed in different remote locations.
Master Point to Point Module
Slave Point to Point Module
Each Master Point to Point Module is connected to a Slave Point to Point Module, equipped in
a remote optical subrack, via a single optical fibre (single-mode SMR 9/125).

1.2 Coverage and Capacity Solutions
The components of SIRIUS, Teko Telecom Modular Coverage and Capacity System, can be
assembled to provide Modular Repeaters, Optical Systems and integrated solutions to improve
coverage in different environments.
1.2.1 Modular Off-air Repeaters - General description
Teko Telecom multi-band multi-operator Off-air Modular Repeaters represent the ideal
solution for cellular coverage extension, offering a cost effective alternative to dedicated BTSs
or Node Bs. They operate over different frequencies and with various frequency combinations
in the 380 to 2700MHz frequency range.
No physical connections are required between the Modular Repeaters and the cellular
network: the Digital Donor Front End Module is connected to a Donor Antenna, providing
the connection towards a BTS or Node B over an air link.
Teko Telecom Modular Off-air Repeaters can be set up by proper combination of Digital Donor
Front End Modules and Service Front End Subracks.
Service Front End Subrack
Donor Front End Modules
The Digital Donor Front End is the single-band/single-operator RF interface towards the
signal source; the Service Front End is the multi-band/single operator equipment that

provides wireless signal to the area to be covered.
Off-air Modular Repeaters can be equipped with one Donor Front End or more Donor Front
End modules to make multiple configurations available: single operator (single band / multiband) and multi-operator (single-band / multi-band).
A single-band single-operator Repeater can be set-up combining a Digital Donor Front End
Module and a Service Front End Subrack.
Up to 4 Digital Donor Front End Modules can be connected to a single Service Front End
obtaining a single-band 4-operator Off-air Repeater.
Digital Donor Front End Modules can be connected to different Service Front End Subracks to
provide multi-band/multi-operator Systems.
Operating principle
Modular repeaters use a directional antenna to interface with the operator’s donor BTS (or
Node B) and one or more service antennas to transmit the amplified wireless signals to the
area to be covered.
In down-link the repeater receives the signals from the BTS (or Node B), amplifies them and
re-transmits them to the mobiles. In the up-link path the repeater receives the signals from
the mobiles (MS), amplifies them and re- transmits them to the base station.
Each DFE module hosts the duplexer, to be connected to the Donor Antenna to separate/
combine Downlink and Uplink paths.

converted into an IF signal by a downconverter. The selection of the band of frequencies or
channels to be extended is handled by a digital filter.
The digital filtering can manage 1 variable band or 2 variable sub-bands.
An upconverter converts the IF signal into an RF signal.
In uplink the signal from the Service Front End Subrack is converted into an IF signal by a
downconverter, filtered and re-converted into an RF signal, amplified by a power amplifier
and re-transmitted to the signal source.
Each TSFE subrack hosts the duplexer, to be connected to a Service antenna to separate/
combine Downlink and Uplink paths.
In Downlink the signals from the Donor Front-End Modules are combined, amplified (High
Power Amplifier) and then transmitted to the area to be covered by the Service Front End
Subrack.
In Uplink, the RF signal from the Service antenna is amplified by a Low Noise Amplifier (LNA)
and split to feed up to 4 Donor Front-End Modules.

1.2.2 Optical Systems - General Description
Teko Telecom Coverage and Capacity System components can be configured to provide a
modular multi-band multi-operator Optical System.
Optical Systems are based on the Radio over Fibre technology, which enables radio signals
transmission over optical fibres. This technology offers wide bandwidth and very little loss
along the fiber optic fibre, allowing the signals to be propagated over long distances. This
allows extensive areas coverage.
Each Teko Telecom Optical System is made up of two main parts: the Master Unit, interfacing
the signal source, and Remote Units, distributed throughout the territory to be served. Master
Unit and Remote Units are connected via single mode optical fibres (SMR 9/125).

options.
Each Master Unit can be equipped with one or more RF interface subracks (subracks hosting
RF interface modules) and with one or more Optical Subracks (Active Subracks hosting Fiber
Optic Transmitter/Receiver modules).
When the Master Unit is equipped with Master and Slave Point to Point Modules, RF interface
subracks and optical subracks can be separated by a maximum distance of 20km.
• RF interface subracks
RF Interface subracks operate over different frequencies and with various frequency
combinations in the frequency range from 380 to 2700MHz.
Each RF interface subrack can be equipped with one or more RF Interface modules. Each
module interfaces to a single mobile operator / mobile standard signal source, making
multiple configurations available: single operator (single band / multi-band) and multioperator (single-band / multi-band).
Master Unit RF Interface modules can be Point of Interface (POI/TAPOI) modules and/or Donor
Front End modules.
Point of Interface modules are connected to the signal source via coaxial cable: each module
is connected to a single operator/ single standard signal source (BTS or Node B). Master Units
equipped with POI/TAPOI modules must be installed next to the donor BTS or Node B.
POI modules can be equipped in passive subracks; TAPOI modules require active subracks
(SUB-TRX).
Donor Front End modules allow the Optical System to be driven without the need of a
dedicated BTS or Node B: each Donor Front End module interfaces with a Donor Antenna
oriented towards a BTS or NodeB (connection over an air link).
Donor Front End modules require an active subrack (SUB-TRX). Each subrack can be equipped
with up to 4 Donor Front End Modules.
RF Interface subracks also host passive modules providing distribution and filtering:
• 1:4 Splitter/Combiner and
• Band Splitter/Combiner (Triplexer) with built-in 1:4 Splitter/Combiner.
Due to the flexible configuration options of Teko Telecom Coverage and Capacity Systems,
the same passive modules can be used for different purposes:
• the 4-way splitter/combiner can be used to manage: multiple RF interface modules,
operating in the same band (Multi-Operator Optical Systems) or multiple Fiber Optic
modules;

• Optical Subracks
Optical Subracks are Active Subracks hosting Fiber Optic Transmitter/Receiver modules.
Fiber Optic
Modules
Fiber Optic Transmitter/Receiver modules are the optical interface towards Remote Units:
they provide RF to optical /optical to RF conversion.
Fiber Optic modules are connected to Remote Units via single-mode optical fiber (SMR
9/125); each Fiber Optic Module can manage up to 4 Remote Units (up to 5 in cascade
configuration).
Up to 6 Fiber Optic Modules can be housed in a single Optical Subrack.
In Downlink RF signals are converted into optical signals in the Fiber Optic Transmitter modules
of the Master Unit and then they are propagated through optical fibre distribution to Remote
Units. In the Fiber Optic Receiver of each Remote Unit, the optical signal is then converted
back into an RF signal that is amplified and transmitted to mobiles through an antenna or a
passive distribution system.
In Uplink RF signal is converted into an optical signal in the Fiber Optic Transmitter of each
Remote Unit and then it is propagated via fibre optics to the Master Unit. Optical signals from
Remote Units are then converted by the Fiber Optic Receiver modules of the Master Unit into
RF signals and transmitted to the signal recipient.

Uplink and downlink optical signals are transmitted over the same single mode optical fibre
(Wavelength Division Multiplexing -WDM- technology).
The Master Optical Subrack also hosts the Supervision Module for the management of the
whole System.
When the Coverage System includes point to point links, each remote optical subrack hosts
the Slave point to point module to be connected, via optical fibre, to its Master Point to Point
module, equipped in the RF interface subracks.
The slave point to point module includes the 4-way splitter/combiner to manage up to 4 Fiber
Optic Transmitter/Receiver Modules and a built-in Supervision unit for the management of

1.2.3 Coverage Systems Management and Power Supply
Management
Teko Telecom Supervision Module (TSPV) allows the management of the entire Coverage and
Capacity System.
The System Supervision Module is able to manage the Active Subrack it is equipped in (Master
Subrack) and up to other 12 Active Subracks (Monitored Subracks).
Twelve ports (1 to 8 and S1 to S4) are available on the Supervision Module front panel to be
connected to the RS485 ports of monitored Active Subracks.
The ports numbered from 1 to 8 are available for the connection to monitored subracks
mounted within the same rack hosting the Master Subrack.
The other four ports (S1 to S4) are available for the management of remote subracks equipped
with Slave supervision units.
When the Coverage System includes point to point links these ports allow the management
of the Slave Point to Point modules built-in Supervision units. Each Slave Point to Point
module Supervision unit manages the remote optical subrack - hosting the module - and all
connected Remote Units.
The Coverage System Supervision Module communicates with the Slave Point to Point builtin Supervision via the single-mode optical fiber (SMR 9/125) connecting Master and Slave
Point to Point modules.
When the Coverage System does not include point to point links, the master supervision
module communicates with the Remote Units via the single-mode optical fiber (SMR 9/125)
connecting Fiber Optic modules to Remote Units.
Address assignement
Each monitored Subrack takes its address from the Supervision Module port it is connected
to (please refer to Paragraph 2.2.2 RS485 Connections for details).
The Active Subrack equipped with the Supervision Module (Master Subrack) takes address
= 0 (zero).
The whole Coverage System can be accessed and managed simply connecting a PC, either
locally or remotely, to to the IP address of the System Supervision Module.

Local management is performed connecting a PC to the Ethernet port (LAN, RJ45 connector),
available on the Supervision Module front panel. A local connection is required to perform
commissioning.
For remote control the System can be accessed via Ethernet, via external PSTN or wireless
modem or via optional built-in wireless modem.
The management of the System is performed via web pages: the Supervision Module is
equipped with a web-server and each component of the System is associated to a web page
displaying detailed information about the component.
The Supervision Module is also equipped with an SNMP-agent, which allows the control of
each parameter of the system via SNMP get/set/trap operations.
The Supervision Module is also provided with an OpenVPN application that allows remote
and secure access to the System using the Internet.
Teko Telecom Operation and Maintenance Terminal (OMT) web pages show the Coverage
System operating parameters and alarm status. They allow the commissioning, monitoring,

setting and troubleshooting of the whole Coverage System.
Teko Telecom Operation Management Centre (OMC) proprietary software allows the
management of multiple Teko Telecom Coverage and Capacity Systems in a Network.
OMC is a client-server application: the server collects information, such as System status
and alarms, relevant to the Systems in the Network. The Server communicates with each
System Supervision Module via Ethernet (TCP-IP socket) or via PSTN or wireless modem.
The Client provides access to the information stored in the Server database. It allows
end-users to check the status of the Coverage Systems in the Network via a user friendly
graphical interface.
