Mobile Phone
How does a Mobile phone (Cellular) network work?
Hi, this is rather urgent. I am doing a project that touches on the cellular network, and I know that radio waves transmitted from a mobile phone in the covered area of a cell site are sent to that cell site before being sent over cell sites until it reaches the cellsite where the receiving mobile phone is at.
However, how does this apply to cross-continent communication when there is a vast expanse of sea preventing the setting up of any cell sites in between to aid the transfer of radio waves?
Are Satellites used to transfer the data in this case? What exactly happens? Please help! =(
Optical fiber is largely use now, to connect master cell sites (which have a number of slave sites) to the phone network. They all don’t network to each other really. They might only if a call is beween mobile units under the control of a master site. Otherwise they go over the phone network to other master sites, other providers, or to non-mobile phones or communication endpoints.
Telephone and data communucations across oceans is largely done with undersea fibre.

Mobile - $34.99 Coronation Street scribe John Fay pens this three-part conspiracy thriller concerning a mobile phone engineer who blames his job for giving him an inoperable brain tumor, and who becomes the prime suspect in a murder investigation when a drug dealer is shot dead and a mobile phone mast is destroyed. Set against the backdrop of the Iraq War, the film opens as mobile phone engineer Eddie (Neil Fitzmaurice) is diagnosed with a deadly brain tumor. Though his wife Donna (Julie Graham) and their two children vow to make his final days truly memorable, all vengeful Eddie can think about is making sure that someone pays. Eddie’s efforts to track down the responsible party backfires though when a murdered drug dealer and a destroyed cell phone mast lead police to suspect that he may be responsible for a series of murders around the city. Also hungry for vengeance is broken soldier Maurice Stone (Jamie Draven), whose wife and son were killed by a driver that was talking on their cell phone. That driver has never been found, and Maurice won’t rest easy until he’s gotten his revenge. Later, when the identity of the hit-and-run driver is finally revealed, the true mastermind behind this mobile phone terror plot finally steps out from the shadows as a labyrinthine conspiracy slowly comes to light. ~ Jason Buchanan, Rovi |
