Abstract: To allow for wireless communications among a specific geographic area, an base stations of communication network must be deployed to allow sufficient radio coverage to every mobile users. The base stations, successively, must be linked to a central hub called the MSC (mobile switching centre). The mobile switching centre allow connectivity among the PSTN (public switched telephone network) and the numerous wireless base stations, and finally among entirely of the wireless subscribers in a system. The global telecommunications control grid of PSTN which associate with conventional (landline) telephone switching centre (called central office) with MSCs all around the world.
