The grounding system consists of the following Sub Systems. Labeling the krone modules like Mc and Rx’s, and tributary cables. Checking mux receiving sensitivity of optical ports by using variable mechanical attenuator.

Power tapping from rectifier to DCDB. Our skilled and motivated teams provide timely and precise maintenance support. By using directional antennas on a base station, each pointing in different directions, it is possible commissionimg sectorise the base station so that several different cells are served from the same location. Several hopping sequences are available, and the sequence in use for a particular cell is continually broadcast by that cell so that it is known to the handsets.

Articles lacking sources from January All articles lacking sources. The functions of a BTS vary depending on bdc cellular technology used and the cellular telephone provider. This subsystem is also referred to as the transcoder and rate adaptation unit TRAU.

Typically two antennas are used per sector, at spacing of ten or more wavelengths apart. It also provides all the required data to the operation support subsystem OSS as well as to the performance measuring centers. 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. The base transceiver stationor BTS, contains the equipment for transmitting and receiving radio signals transceiversantennasand equipment for encrypting and decrypting communications with the base station controller BSC.

Checking mux receiving sensitivity of optical ports by using variable mechanical attenuator. GSM standard Telecommunications infrastructure. Checking the transmitting power of both the optical ports using power meter.

Earthing the rack, and mux, from the earthing bar less than 1 ohm in the commiswioning. Kroning the E1’s in their respective krone modules Tx, Rx.

Base station subsystem

Rack Installation The rack for the installation of indoor unit and other equipment will be jnstallation in the equipment room by grouting the bolts in the floor. Our turnkey solutions offer customer the choice from one or more of our services to meet the communication requirements. RF, VF, Power, E1 cables etc for military vehicles Supply, installation and commissioning of broad band radios, survive lance cameras Provision of networking solutions.

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 qnd interference.

From Wikipedia, the free encyclopedia. This allows the operator to overcome the effects of fading due to physical phenomena such as multipath reception. This article does not cite any sources. Antenna combiners are implemented to use the same antenna for several TRXs carriersthe more TRXs are combined the greater the combiner loss will be.

This information allows the handsets to identify the network and gain access to it. Checking mux Tx power of all out ports. Unsourced material may be challenged and removed. This modulation is a kind of continuous-phase frequency shift keying. A BSC is often based on a distributed computing architecture, with redundancy applied to critical functional units to ensure availability in the event of fault conditions.

Frequency hopping is often used to increase overall BTS performance; this involves the rapid switching xommissioning voice traffic between TRXs in a sector. E1 cable routed at TX. Redundancy often extends beyond the BSC equipment itself and is commonly used in the power supplies and in the transmission equipment providing the A-ter interface to PCU. Earthing the rack, and mux, from the earthing bar less than 1 ohm in the shelter. Optimization and Monitoring System performance monitoring Traffic engineering Hand commissiojing analysis Interference analysis Drive test and field measurement analysis.

Installing the tributary cables from mux to Digital Distribution Frame. Labeling the krone modules like TXs and RXs, and tributary cables. The databases for all the sites, including information such as carrier frequenciesfrequency hopping lists, power reduction levels, receiving levels for cell border calculation, are stored in the BSC.

MW Antenna Installation The mounting accessories btx the MW antennae will be inspected and the mounting arrangements will be organized for the required orientation. Installation will be done for two link heads. We are here to provide services for design, installation, testing, commissioning, maintenance and bfs of telecommunication network and enterprise solutions.

Typically these directional antennas have a beamwidth of 65 to 85 degrees. It usually involves the following:
