This Allows Efficient Use Of The Limited Radio Spectrum Allocated To Mobile Services, And Lets Thousands Of Subscribers Converse At The Same Time Within A Given Geographic Area.
Mobile Phones Communicate With Cell Towers That Are Placed To Give Coverage Across A Telephone Service Area, Which Is Divided Up Into 'cells'. Each Cell Uses A Different Set Of Frequencies.
A central processing unit (CPU), the processor of phones. The CPU is a microprocessor fabricated on a metal–oxide–semiconductor (MOS) integrated circuit (IC) chip.
Additionally, Short-range Wi-fi Infrastructure Is Often Used By Smartphones As Much As Possible As It Offloads Traffic From Cell Networks On To Local Area Networks.
In Order To Handle The High Traffic, Multiple Towers Can Be Set Up In The Same Area (Using Different Frequencies). This Can Be Done Permanently Or Temporarily Such As At Special Events.
Due To Bandwidth Limitations Each Cell Will Have A Maximum Number Of Cell Phones It Can Handle At Once. The Cells Are Therefore Sized Depending On The Expected Usage Density.
