BackgroundBackground

Rapid growth in population and technology Rapid growth in population and technology has increased telecom subscribers in has increased telecom subscribers in Pakistan.Pakistan.

Mobile network is the heart of the Mobile network is the heart of the telecommunication industry in Pakistan telecommunication industry in Pakistan with the highest number of subscribers.with the highest number of subscribers.

Mobile Networks in Pakistan operate at Mobile Networks in Pakistan operate at GSM.GSM.

Base Transceiver Base Transceiver Station(BTS)Station(BTS)

GSM networks use BTS GSM networks use BTS towers to provide towers to provide network reception. network reception.

Cell or Sector antennas Cell or Sector antennas are attached on these are attached on these towers to provide towers to provide coverage to a specific coverage to a specific area.area.

GSM operators require GSM operators require regular maintenance of regular maintenance of the Cell Antennas to the Cell Antennas to ensure good quality of ensure good quality of service.service.
