The Manufacturer’s rated output power of this equipment is for single carrier operation. For situations when multiple carrier signals are present,
the rating would have to be reduced by 3.5dB, especially where the output signal is re-radiated and can cause interference to adjacent band
users. This power reduction is to be by means of input power or gain reduction and not by an attenuator at the output of the device.
La puissance de sortie nominale indiquée par le fabricant pour cet appareil concerne son fonctionnement avec porteuse unique. Pour des appareils
avec porteuses multiples, on doit réduire la valeur nominale de 3,5dB, surtout si le signal de sortie est retransmis et qu’il peut causer du brouillage
aux utilisateurs de bandes adjacentes. Une telle réduction doit porter sur la puissance d’entrée ou sur le gain, et ne doit pas se faire au moyen d’un
atténuateur raccordé à la sortie du dispositif.

Teko DAS Platform Technical Handbook Doc ID Number 91 080 0783 rev. 01 | page A10
TEKO DAS Platform
Teko Platform ComponentsPart A.
OverviewA1
The Teko Platform is a versatile, modular, multi-technology platform designed to oer exible
and reliable wireless coverage and capacity for both indoor and outdoor environments. Teko’s
design delivers the maximum end-user performance, supporting Time Division LTE technology
and LTE-Advanced capabilities to enable multi-path performance with the exibility to adapt
coverage and capacity in any venue on an event-by-event basis.
The DAS (Distributed Antenna System) Platform is made up of two main elements: Master
Unit and Remote Units.
Teko Master Unit
The Master Unit is a rack-based platform delivering modularity that allows congurations
for dierent needs and a future-proof design to ensure you can adapt your venue to future
technologies. The Master Unit is congured to provide both the RF interface (o-air and/or
via coaxial cable) towards the signal source (BTS, NodeB, Donor) and the optical interface
towards Remote Units. It also hosts the Supervision Module for the management of the entire
System utilizing secure browser technology that enables administration from any location.
The Master Unit can be congured utilizing Donor Front End, Active Point of Interface or DAS
Trays to provide exible options to connect to any combination of Carrier interfaces. The Teko
Platform also includes the optional Multiband Spectrum Analyzer (MSA) to allow recordable
and remote monitoring of venue performance to enable easy optimization.
Architecture
The modular sub-rack allows adaptation of deployment needs including the addition of newer
technologies within sub-racks that prepares venues to be more adaptive to venue needs
(e.g. new sectors) and to introduce newer services into the existing venues DAS. The Master
Units DAS shelf and architectural design minimizes system footprint, saving 30-70% of critical
space requirements within venues, BTS Hotels, Co-location environments. The Teko system
design allows for passive repeater or active / optical DAS congurations and the system can
be recongured as needs change.
Teko Remote Units
Remote Units (RUs) are connected to the Master Unit via a single mode optical ber to
distribute multiple frequency bands and multiple Carriers/MNOs to each Remote Unit, or to
multiple RUs to congure multipath (e.g. MIMO) congurations.
Remote Units are self-contained and provide signal distribution to a range of both indoor and
outdoor antennas.
As integral elements of the system all Teko Remote Units can be congured from a single

administrative interface at the master units. This includes applying new rmware versions to
the Teko system and its RUs.
Multi Power Options
Teko Remote Units are available in dierent power classes using multi-carrier ampliers that
can be driven simultaneously by the same Master Unit. This provides a exible solution to
distribute capacity or extend coverage into dierent locations (indoor and outdoor) at the
same time, for example in tunnels, undergrounds, airports, high rise buildings, shopping
malls and campuses.
This technical handbook describes the components of the Teko Platform and how these
components can be assembled to provide Optical Systems (DAS) and rack mounted modular
O-air Repeaters to improve coverage in dierent environments.

Teko Digital Donor Front End (TDFE)•
The Digital Donor Front End Module is the single-band/single-operator System RF interface
towards a Donor Antenna, providing Downlink digital ltering and Uplink Power Amplier.
No physical connections are required between the DFE and the cellular network: the Donor
Antenna provides the connection to a BTS or NodeB/e-NodeB over an air link.
Coverage Systems can be equipped with one or more Donor Front End modules to make
multiple congurations available: single operator (single band / multi-band) and multi-
operator (single-band / multi-band).
Digital Donor Front End (TDFE)Figure A10 –
A single-band single-operator modular O-air Repeater can be set up combining a Digital
Donor Front End Module and a Service Front End (Teko 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 O-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 NodeB/e-NodeB. 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.

TEKO DAS Platform
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 preamplied by a Low Noise Amplier and
converted into an IF signal by a down converter. The selection of the band of frequencies or
channels to be extended is handled by a digital lter.
The digital lter can manage 1 variable band or 2 variable sub-bands (standard version). A
fully equipped version is available to manage up to 9 variable sub-bands.
An up converter 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 down converter, ltered and re-converted into an RF signal, amplied by
a power amplier and re-transmitted to the signal source.

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 bers, with Uplink and Downlink signals transmitted
over a single strand of ber (Wavelength Division Multiplexing -WDM technology).
Dierent congurations 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 conguration can manage up to 4 Remote
Units.
The Fiber Optic Transmitter/Receiver Module in 1:1 conguration is able to drive up to 5
cascaded Remote Units with dierent wavelengths in Uplink.

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 slave optical subracks.
The point to point link is suitable when the signal source (BTS, NodeB/e-NodeB, 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 strand of optical ber, thus providing
a signicant reduction in the number of ber 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 (slave) optical subracks to be equipped with Slave Point
to Point modules. The RF Interface subracks can be equipped with up to 4 Master Point to
Point modules for the management of up to 4 optical subracks, installed in dierent remote
locations.
Point to Point Modules: Master (left) and Slave (right)Figure A17 –
Master and Slave Point to Point Modules are connected via a single optical ber (single-mode
SMR 9/125).
Each Slave optical subrack can be equipped with up to 3 Slave Point to Point Modules for the
coverage of up to 3 sectors.

Coverage and Capacity SolutionsA3
The components of the Teko Platform can be assembled to provide Modular Repeaters, Optical
DAS and integrated solutions to improve coverage in dierent environments.
Rack-mounted Modular RepeaterA.3.1
The Teko platform can be congured for RF repeater applications where the need for optimized
signal coverage is adequate to provide better end-user service that is transparent to protocol
and modulation.
Populating the Teko Master Unit with digital Donor Front End (DFE) and service front-end
modules, multi-band, multi-operator coverage solutions can be congured.
The modularity of the Teko platform allows easy adaptability to new technologies or extending
the solutions to additional operators as needed.
No physical connections are required between the Modular Repeaters and the cellular network:
the Digital Donor Front End is connected to a Donor Antenna, providing the connection
towards a BTS or NodeB/e-NodeB over an air link.
Donor Front End Modules
Service Front End
Rack-mounted Modular Repeater exampleFigure A51 –
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 enhanced wireless signal to the area to be covered.

TEKO DAS Platform
Multiple DFEs (up to 4) can be connected with a single service front-end for single band,
multi-operator congurations. Multiple service front-ends can be utilized with multiple DFEs
to create multi-band, multi-operator solutions.
Operating principle
Modular repeaters use a directional antenna to interface with the operator’s donor BS and one
or more service antennas to transmit the amplied wireless signal to the area to be covered.
In downlink the repeater receives the signals from the BS, amplies them and re-transmits
them to the mobiles. In uplink the repeater receives the signals from the mobiles (MS),
amplies them and re- transmits them to the base station.
When Modular Repeaters do not provide satisfactory coverage (extensive areas, long tunnels),
they can be used along with a ber fed System (Teko Optical DAS).

TEKO DAS Platform
Optical DASA.3.2
The Teko Platform components can be congured to provide multi-carrier Optical Distributed
Antenna Systems.
Optical Systems are based on the Radio over Fiber technology, which enables radio signal
transmission over optical ber. This technology oers wide bandwidth and very little loss
along the ber optic cable, allowing the signals to be propagated over long distances. This
allows extensive areas coverage.
Each Teko Optical DAS 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 ber (SMR 9/125).
Master UnitA –
The Master Unit provides both the RF interface towards the signal source (one or more BTSs
or NodeBs/e-NodeBs) and the optical interface towards Remote Units.
It is a rack-based modular equipment: Teko Coverage and Capacity Systems components can
be assembled in a variety of ways providing dierent Master Unit conguration options.
Each Master Unit can be equipped with one or more RF interface subracks, hosting RF interface
modules and with one or more Optical 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 dierent 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.
Master Unit RF Interface modules can be Point of Interface (POI/TAPOI/TDTPOI) modules and/
or Donor Front End modules.
Master Units equipped with POI/TAPOI/ TDTPOI modules must be installed next to the donor
BTS or NodeB/e-NodeB).
POI modules can be equipped in passive subracks; TAPOI/TDTPOI modules require active
subracks (SUB-TRX).
Donor Front End modules allow the Optical DAS to be driven without the need of a dedicated
BTS or NodeB/e-NodeB: each Donor Front End module interfaces with a Donor Antenna
oriented towards a BTS or NodeB/e-NodeB (connection over an air link).
Active Subracks are required to host Digital Donor Front Ends; fully equipped Digital Donor
Front Ends require deep Active Subracks (depth = 360mm / 14.17in). Each subrack can be
equipped with up to 4 Donor Front End Modules.

Band Splitter/Combiner (Triplexer) with or without built-in 1:4 Splitter/Combiner•
Pentaplexer/Esaplexer.•
Due to the exible conguration options of Teko Coverage and Capacity Systems, the same
passive modules can be used for dierent purposes:
the 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;
the triplexer (with built-in 4-way Splitter/Combiner) can be used to manage•
up to 3 RF interface modules operating in dierent bands (and up to 4 Fiber Optic -
Transmitter/Receiver Modules) or
up to 3 Service Front End subracks operating in dierent bands (and up to 4 Fiber Optic -
Transmitter/Receiver Modules) or
up to 3 four-way splitter/combiner modules, used to manage multiple RF interface -
modules -up to 4 for each band (and up to 4 Fiber Optic Transmitter/Receiver Modules).

dierent bands or
up to 5 (Pentaplexer)/ up to 6 (Esaplexer) four-way splitter/combiner modules- used to -
manage multiple RF interface modules (up to 4 for each band).
The RF Interface subracks can also host up to 4 Master Point to Point modules for the
management of up to 4 optical subracks installed in dierent remote locations.
Digital Donor Front End modules can be connected to Service Front End Subracks to provide
coverage to the area adjoining the Master Unit site.
Each Service Front End can be fed by up to 4 Donor Front-End Modules interfacing the signal
source. Downlink and uplink auxiliary ports are available to drive the Optical System.

Fiber Optic
Modules
Optical Subrack (example)Figure A53 –
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 ber (SMR
9/125); each Fiber Optic Module can manage up to 4 Remote Units (up to 5 in cascade
conguration).
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 ber 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 amplied 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 ber 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 ber

(Wavelength Division Multiplexing -WDM- technology).
When the Coverage System includes point to point links, the remote optical subracks host the
Slave point to point modules to be connected, via optical ber, to their Master Point to Point
modules, 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 the remote optical subrack, the power supply subrack (SUB-PSU-MU or SUB-PSU-MU/48,
when equipped), and all connected Remote Units.
When Remote optical subracks are equipped with 2 or 3 Slave Point to Point Modules only
one module is connected to the System Supervision module (the one installed on the left side
of the remote subrack - slots 1 to 6).

Coverage Systems Management and Power SupplyA.3.3
Coverage Systems can be accessed and managed simply connecting a PC, either locally or
remotely, to the IP address of the System Supervision Module.
The Supervision Module Communication Interfaces (Ethernet LAN port / Modem) allow the
System to be managed either by a Local Maintenance Terminal (LMT), connected locally to
the Supervision Module LAN port, or by a Network Element Manager (NEM). The connection
with a Network Element Manager (NEM) can be either a physical (Ethernet LAN) or a modem
connection.
The optional wireless modem (GSM/GPRS or GSM/GPRS/UMTS), integrated inside the
Supervision module, allows the Coverage System remote management. A VPN application
installed on the Supervision Module provides remote and secure access to the System using
the Internet. An embedded SNMP agent software is available to provide a Northbound SNMP
interface, allowing easy integration into upper level Network Management Systems (NMS).
The management of the System is performed via JMA Wireless Teko OMT (Operation and
Maintenance Terminal) 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.
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. Please refer to JMA Wireless Teko OMT web pages User’s Guide for details.
Teko Operation Management Centre (OMC) proprietary software allows the management
of multiple Teko Coverage and Capacity Systems in a Network. Please refer to Teko OMC
User’s Guide for details.
A single Teko Supervision (TSPV) allows the management of an entire Coverage and Capacity
System:
Rack-mount Light Supervision shelf Ì
A rack mount Light Supervision shelf is available for modular repeaters or small/medium
DAS: it is able to manage up to 4 Active Subracks. Four ports (RS485) are available on
the Supervision front panel to be connected to the RS485 ports of monitored Active
Subracks.

Supervision Module Ì
A Supervision module is available for the management of more sophisticated Teko DAS
architectures: the module is able to manage the Active Subrack it is equipped in (Master
Subrack), the power supply subrack, up to other 12 Active Subracks (Monitored Subracks),
and all connected Remote Units.
Supervision Module with optional wireless modem (left) without wireless modem (right)Figure A60 –
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.
Ports numbered from 1 to 8•
The ports numbered from 1 to 8 are available for the connection to monitored subracks
mounted within the same rack hosting the Master Subrack.
Ports numbered from S1 to S4•
The other four ports (S1 to S4) are available for the management of remote active
subracks equipped with Point to Point Slave modules.
The Slave Point to Point module installed on the left side of the remote slave subrack
(slots 1 to 6) manages the remote optical subrack, the remote power supply subrack
(if any), and all connected Remote Units. The Coverage System Supervision Module
communicates with the Slave Point to Point built-in Supervision via the single-mode
optical ber (SMR 9/125), connecting Master and Slave Point to Point modules.
The ports S1 to S4 not connected to remote subracks can be used to manage additional
subracks, mounted within the same rack hosting the Master Subrack.
Additional RS485 port available on the Master Subrack rear panel•
The RS485 connector, available on the rear panel of the SUB-TRX-PSU hosting the
Supervision module, provides an additional port for the management of the power
supply subrack (SUB-PSU-MU or SUB-PSU-MU/48). This port is used only when the
System is equipped with the power supply subrack in addition to other 12 monitored
Active Subracks, connected to the Supervision Module RS485 front ports.

The RS485 port, available on the rear panel of a Remote Point to Point Slave Subrack, is
used only when a SUB-PSU-MU or SUB-PSU-MU/48 is installed to provide power supply
to the remote subracks.
Address assignment
Each monitored Subrack takes its address from the Supervision Module port it is
connected to (please refer to Paragraph B.4.2 RS485 Connections for details).
The Active Subrack equipped with the Supervision Module (Master Subrack) takes address
= 0 (zero).
