Services

Installation of BTS / MW Equipment
SNS undertakes turnkey installation & de-installation projects for complete telecom networks. Our installation Teams have experience on various telecom equipment from vendors such as Ericsson, Siemens, Lucent, Nokia, Nortel, Samsung, ECI, NEC etc.

BTS ( Outdoor )

> Fixing of cable ladder for supporting
> Outdoor work consists of fixing of RF antenna and Microwave antenna
> Routing of cables
> Clamping
> Ground / Earthing
> Alignment of Antenna as per specifications

BTS ( Indoor )
> Installation of Radio Base Station (RBS)
> Installation of Tx. Rack
> Fixing of cable ladder
> Grounding of equipments
> Installation of rectifier and battery bank

GSM Antenna Installation

The installation of antenna mounting pipes associated with mechanical arrangement will be examined and where necessary corrected to ensure the following: -
> Desired Orientation
> Desired Height
> Grounding
> Lighting Protection

Antenna Installation Process

The antenna installation will be carried out using the following resources: -
> Trained team
> Expert supervision
> Site Master
> E1 Tester
> SDH Analyzer

Testing and Commissioning of BTS / MW Equipment

SNS undertakes the task of testing and commissioning of telecom equipment on site. It usually involves the following:-
DLC (Digital Loop Carrier)
Teams have successfully completed the works of DLC to the reputed clients like, Airtel, TATA with UT Starcom equipment, the project includes:-
> DLC rack and installation of cards like FXS, PRM, E1 and BRI will be installed by our engineers
> FXS cables routed at MDF frame and kroned.
> E1 cable routed at TX. rack and kroned.
> Power cables routed and connected to DLC rack and power up the DLC.

FSO

FSO projects had been successfully completed by our teams for the clients like Vodafone, TATA etc, with light point equipment.
> Installation will be done for two link heads.
> Installation of MUX.
> Power-up to Mux and link head.

Alignment & Commissioning of linkhead

LOS (Line of Sight Survey)
Our Engineers prior to MW Installation also do Line Of Sight between these two sites and this. The following are the equipments used by our surveyors to complete the process successfully:-
> GPS
> Binoculars
> Altimeter
> Compass
> Digital Camera
> Topographic maps

The surveyors need to reach the site A where the survey has to be conducted and looks towards Site B for the Line Of Sight with the help of above said equipments.

All the obstruction which are observed in the path are recorded and applied in to the Software of PATHLOSS to get determine the height with reference to AMSC (Average Mean Sea Level) of MW antenna and Azimuth be installed to get the LOS cleared.

MW Antenna Installation

> The mounting accessories of the MW antennae will be inspected and the mounting arrangements will be organized for the
required orientation.
> The antennae, the wave-guide locks, flexible wave guides will be fixed with due care taken to ensure reliable and proper RF connections.
> The outdoor radio unit & antenna support arms are finally fixed.
> Alignment of Antenna of the link will be done to achieve the required signal level.

TNMS ( Telecom Network Management Systems )

After the completion of Installation & Commissioning of MW Antenna there is a need to monitor these MW links between the sites from MSC. This online monitoring will be done by TNMS software by our engineers.

Rack Installation

The rack for the installation of indoor unit and other equipment will be installed in the equipment room by grouting the bolts in the floor. The rods will be used if additional support is required.

Installation & Commissioning of Multiplexers in MSC, BSC and Cell Sites
> Installing the mux in the rack and powering up from DC Distribution Box.
> Installing The NVM (Non Volatile Memory) cards in the Mux.
> Installing The DCDB in the rack.
> Power tapping from rectifier to DCDB.
> Installing the tributary cables from mux to Digital Distribution Frame.
> Kroning the E1s in their respective krone modules (Tx, Rx).
> Labeling the krone modules like TXs and RXs, and tributary cables.
> Earthing the rack, and mux, from the earthing bar (less than 1 ohm) in the shelter.
> Commissioning of mux.
> Giving IP Address for DCC and Ethernet for management purpose.
> Checking all kroned E1s with giving local loops from PC by using Bit Error Rate (BRR) Meter.
> Checking mux Tx power of all out ports.
> Checking the transmitting power of both the optical ports using power meter.
> Checking mux receiving sensitivity of optical ports by using variable mechanical attenuator.
