Overall, this means that networks are often structured to have many BSCs distributed into regions near their BTSs which are instqllation connected to large centralised MSC sites. Earthing the rack, and mux, from the earthing bar less than 1 ohm in the shelter.
RF, VF, Power, E1 cables etc for military vehicles Supply, installation and commissioning of broad band radios, survive lance cameras Provision of networking solutions. Earth conductor runs from the lightning protection system, Principal ground bar maintained as reference in the shelter for electronic equipment, DG neutral and DG body to the respective earth pits. Please help improve this article by adding citations to reliable sources. This data is obtained directly from radio planning engineering which involves modelling of the signal propagation as well as traffic projections.
This subsystem is also referred to as the transcoder and rate adaptation unit TRAU. It also provides all the required data to the operation support subsystem OSS as well as to the performance measuring centers. Time bound tasks are planned to execute the projects. Some vendors have implemented it in a stand-alone rack using a proprietary interface. Labeling the krone modules like TXs and RXs, and tributary cables.

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: Checking the transmitting power of both the optical ports using power meter.
This allows the operator to overcome the effects of fading due to physical phenomena such as multipath reception.
Installing the tributary cables from mux to Digital Coommissioning Frame. The BSS carries out transcoding of speech channels, allocation of radio channels to mobile phones, pagingtransmission and reception over the air interface and many other tasks related to the radio network.
There are vendors which build their BTSs so the information is preprocessed, target cell lists are generated and even intracell handover HO can be fully handled. Articles lacking sources from January All articles lacking sources. Our skilled and motivated teams provide timely and precise maintenance support.
In GMSK, the signal to be modulated onto the carrier is first smoothed with a Gaussian low-pass filter prior to being fed to a frequency modulatorwhich greatly reduces the interference to neighboring channels adjacent-channel interference.
E1 cable routed at TX. MW Antenna Installation The mounting accessories of the MW antennae will be inspected and the mounting arrangements will be organized for the required orientation. Bamacom btz and expertise facilitates preparing authentic proposals and obtaining necessary Right of Way approvals from statutory bodies. It performs some of the processing tasks of the BSC, but for packet data.
Ongoing projects – Telex Engineering
Unsourced material may be challenged and removed. The antennae, the wave-guide locks, flexible wave guides will be fixed with due care taken to ensure reliable and proper RF connections. Power tapping from rectifier to DCDB. The functions of a BTS vary depending on the cellular technology used and the cellular telephone provider.
Some amplification of the received signal as it leaves the antenna is often used to preserve the balance between uplink and downlink signal. Power tapping from rectifier to DCDB. Views Read Edit View history.

Installation & Commissioning (MW/BTS/BSC/MSC)
Typically a BTS for anything other than ksc picocell will have several transceivers TRXs which allow it to serve several different frequencies and different sectors of the installaation in the case of sectorised base stations. Frequency hopping is often used to increase overall BTS performance; this involves the rapid switching of voice traffic between TRXs in a sector.
January Learn how and when to remove this template message. Checking mux Tx power of all out ports. Antenna combiners are implemented to use the same antenna for several TRXs carriersthe more TRXs are combined the greater the combiner loss will be. Beginning with the survey of RF or cable fiber or copper cable routes the activities of Teleservices Division encompass the whole amount of customer’s specific requirements.
A TRX may lose some of this capacity as some information is required to be broadcast to handsets in the area that the BTS serves.
The advantage in this case is less load on the expensive Abis interface. From Wikipedia, the free encyclopedia. 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. Kroning the E1s in their respective krone modules Tx, Rx. The allocation of channels between voice and data is controlled by the base station, but once a channel is allocated to the PCU, the PCU takes full control over that channel.
Typically two antennas are used per sector, at spacing of ten or more wavelengths apart. A key function of the BSC is to act as a concentrator where many different low capacity connections to BTSs with relatively low utilisation become reduced to a smaller number of connections towards the mobile switching center MSC with a high level of utilisation. Retrieved from ” https: Checking mux receiving sensitivity of optical ports by using variable mechanical attenuator. Site Preparation Site survey, site negotiations and site acquisition Assistance in statutory clearances Infrastructure set up including supply of infrastructure items, as per customer requirement.
The following are the equipments used by our surveyors to complete the process successfully:
