A Brief Look at Mobile Phone Technology
A mobile phone, also known as mobile phone, mobile cell, mobile phone or simply cell, phone or hand phone, some times shortened to just mobile, hand phone and sometimes called by other names, is a mobile phone that will make and receive calls via a radio signal, usually from a base station to a receiver, in a public switched telephone network. This service has increased greatly in popularity with the availability of new cell phones which operate on the same operating systems and protocols as standard telephone handsets, which allows users to talk with each other regardless of their location. A mobile handset can be used anywhere there is a mobile service provider and often comes with a SIM card so it is possible to continue using the same service as you would have if you were using a landline.
The majority of modern cell phones today come equipped with a call list which allows the owner to dial pre-programmed numbers from this list for both outgoing and incoming calls. The calls made from a mobile phone are sent from the device to the holding unit where it is recorded by the microprocessor and forwarded to the person’s intended destination. Calls are received by the mobile phone from other mobile phones, from a variety of sources and from landlines too. The amount of usage a particular mobile phone has will affect the call statistics received, but this is an important factor when assessing usage since most mobile phones will only make calls when they are requested by the user.
Mobile service providers offer varying rates for their services. The rates vary between providers and may be regulated by federal, state or regional laws. It should also be noted that in some places, it is illegal to make phone calls using cell phones, and those who do are subject to prosecution. In addition, the use of a mobile device while driving has become more restrictive, especially with the use of handheld GPS devices which are illegal in some areas. As always, it is important to choose a plan that best meets your needs before proceeding with any plan.
