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.
Once These Few Channels Were In Use By Customers, No Further Customers Could Be Served Until Another User Vacated A Channel. It Would Be Impractical To Give Every Customer.
In The Earliest Mobile Phone Systems By Contrast, All Control Was Done Manually; The Customer Would Search For An Unoccupied Channel And Speak To A Mobile Operator To Request Connection.
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 display which echoes the user's typing, and displays text messages, contacts, and more. The display is typically either a liquid-crystal display (LCD) or organic light-emitting diode (OLED) display.
A battery, providing the power source for the phone functions. A modern handset typically uses a lithium-ion battery (LIB), whereas older handsets used nickel–metal hydride batteries.
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.
Cell Phone Companies Will Bring A Truck With Equipment To Host The Abnormally High Traffic.Capacity Was Further Increased When Phone Companies Implemented Digital 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.
