Maximise your network coverage area

The LGP Telecom range of coverage enhancement products originates from the

successful SuperCompact™Tower Mounted low noise Amplifier (TMA) productfamily. The new Booster product family, called Tower Mounted Booster (TMB)

amplifiers, addresses the transmit path of cell extension by including booster amplifiers

for the transmit portion. The LGP TMB provides coverage enhancement in both up

and down link.

Total coverage

A mobile phone system is no longer just a complementary telephone system, it is fast

becoming the primary way of communicating. The success of a network depends on

an even higher demand on performance and reliability. The network with the most

comprehensive coverage will be the winner. This includes difficult geographical

regions which are sparsely populated as well. Full coverage is often mandatory.

Cost efficiency

Providing comprehensive coverage using traditional BTS hardware is costly and

relatively complicated. At higher frequencies like 1800/1900 MHz the cost is even

more significant as the number of base stations required is higher than at 800/900

MHz. With LGP’s Tower Mounted Booster and a micro or pico base station you get

macro base station coverage in your network with minimised investments which

means lower infrastructure cost per square kilometre.

LGP Telecom’s Tower Mounted Booster products can increase your existing cell

coverage by up to 60%, or for new networks, reduce the number of required base

stations by up to 30%.

Moreover, the TMB reduces the output power requirement of the BTS, allowing

micro BTSs or Pico BTSs to be used much more widely compared to today.

LGP Tower Mounted Booster systems

A TMB system is a cost efficient solution for areas with low traffic capacity requirements,such as highway coverage, rural areas, inter city connections, etc. The LGP TMB systemwill provide extension of mobile traffic to the local base station. Having low noiseamplifiers for the up-link path will increase the sensitivity of the system and herebyincrease the usable cell size. The booster amplifiers in the down link path will equallyincrease the EIRP of the antenna and thereby complement the improved up-link,resulting in a balanced coverage equivalent to a macro cell.

The TMB system concept from LGPTelecom includes a unique featurefor flexible installation.The maincontroller of the TMB system is theControl Interface Unit (CIU).TheCIU is a small separate unit, thateasily can be located at or inside theBTS.

The flexible positioning of the CIUprovides easy ”access” to the TMBindependent of the positioning ofthe TMB which can be located in atower or on the side of a building.

Software controlled

The controller/software constitutes of three parts: the software in the TMBitself, the software in the Control Interface Unit (CIU) and the software in theWindows PC.

Control, maintenance and supervision of the TMB are provided through auser-friendly Windows oriented software application. The Operation andMaintenance (O&M) functions are handled through a PC. The connectionfrom the O&M laptop to the CIU is either via a RS232 cable or wireless via aninfrared (IrDa) interface.

The software provides total control of the TMB in just a few windows enablingconfiguration of carriers, gain, power, alarms, system message monitoring andmuch more. The ”intelligent” part of the controller/software is in the CIU.The software is stored in Flash-memory, which enables easy downloading offuture software upgrades.

Outdoor Booster

The TMB system from LGP Telecom is a robust unit which has undergone extensiveenvironmental tests. Both the TMB and the CIU are designed for outdoorapplications.

Easy installation

The TMB system is designed for easy and flexible installation using a so called”click-on” mounting plate. The robust mounting plate is easily installed on a pole ora wall. Due to its low weight, the mounting plate is easy to position and fasten. TheTMB itself can then be hooked onto the mounting plate and securely fastened. Ahandle on the TMB enables easy handling of the unit as well as provides a fixingfor hoisting the unit in tower installations.

Failure security

Configuration parameters are stored in a non-volatile memory, so that the TMBcan be up and running again quickly after e.g. a power failure. Furthermore, theTMB has several recovery- and auto-start-up procedures built-in.

Remote Access

As a product option the LGP TMB can be accessed remotely via a mobile phoneor a GSM modem. Via this Remote Access all control and alarm facilities can beaccessed.

Plug and Play

Enter desired output power and hit ”calibration”. The TMB can either be manuallyor automatically gain configured.

Control and Alarm Communication

The LGP Telecom TMB provides several ways of control interfacing, local or remote.Supervision and control are performed either remotely via a RS232 interface orlocally via the alarm interface and the infrared IrDa interface.

Power Monitor

The TMB has a Power Monitor function which indicates the output power of theunit. This facilitates the installation and is a useful tool to verify that everything works.

Antenna Monitor

Another product option is that the TMB contains an Antenna Monitoring facility.Most Base Stations have such a function on board already, but adding a boosterprevents this function to monitor the antenna. By having the Antenna Monitoringfunction in the TMB the supervision of malfunctioning antennas is re-established.

Remote Access

As a product option the TMB can be entirely remote controlled via a modem, a

GSM modem or a mobile phone.

Antenna Monitor

Most Base Stations are equipped with a facility to monitor the feeder cables and the

antennas. Adding a TMB after the feeder cable and before the antennas will interrupt

the monitoring of faulty antennas. The LGP TMB has an Antenna Monitor facilityas well. Deploying this product option re-establishes the antenna supervision and

leaves the feeder supervision to the VSWR monitor in the BTS.

Battery Backup

The Battery Backup Unit (BBU) is designed as a complementary product for LGP

Telecom’s family of Tower Mounted Boosters (TMBs). With the recommended

battery type the BBU has the capability to supply 600 W continuously for more than

two hours. Thus the BBU can supply a TMB (2 x 20 W) for more than four

hours, or the combination of a TMB and a micro BTS for more than two hours. As anoption the BBU can also support a 24 V micro BTS up to 300 W.

Lightning Protection

The TMB has built-in lightning protection on all ports. All RF ports fulfill therequirements from EN 50 082-2, ETS 300 392-3 and IEC-ENV 60 13 12-1. The 48

VDC or 115/230 VAC port on the TMB is rated to EN 50 082-2 and ETS 300 392-3.

A more severe lightning protection on the power supply port (like class IEC-ENV

60 13 12 -1) can be obtained using LGP Telecom’s Lightning Protection Unit

(LPU).

The LPU is a small separate unit which must be placed next to the TMB. It contains

high class lightning protection circuitry and will protect the main power supplyline input of the TMB.

High quality

The TMB system from LGP Telecom is designed for severe environmental conditionsand extensive operation over long periods of time. The number of components,interconnections etc. have been cut down to a minimum and each one carefullyselected to provide optimum performance with maximum reliability. There are nomoving mechanical parts inside the TMB. All material is carefully chosen and allmechanical parts are surface treated to prevent corrosion. The company is ISO9001certified and the quality is constantly monitored/improved on all company levels,throughout the process from design to shipping and after sales service.

Thermal design

Much effort has been put in the thermal design of the TMB. A two carrier 20 WattTMB will dissipate approximately 200 W in heat. All major heat dissipatingcomponents are directly mounted on the heat sink and widely spread out over theentire surface. The TMB is designed for non-forced cooling. Reliability and MTBFare closely linked to temperature, therefore compromising on proper cooling willhave fatal influence on the MTBF. The LGP TMB is conservatively dimensionedand has a fair margin to component specifications. In the unlikely event of overheating,a built-in microprocessor based security function activates an alarm and reduces RFoutput power to protect components and total loss of the unit (damage protection).Hereby it is ensured that the site will not ”go down” even at extreme conditions,but will gracefully degrade performance temporarily.

Safety

The LGP TMB has been designed with respect to the relevant international standards.Electrical safety meets EN standards and includes over-voltage protection. EMCand CE regulations are met and the product has been marked accordingly.

Lightning protected

As the product is meant to be installed close to the antennas and therefore even inmast tops, it is properly protected against lightning. Due to the vaste success of theunique protection circuitry experienced from LGP’s successful Tower MountedAmplifier products lightning production has also been adopted by this product.
