3. Introduction A mobile phone, cellular phone, cell phone, cellphone, hand phone, or hand phone, sometimes shortened to simply mobile, cell or just phone, is a portable telephone that can make and receive calls over a radio frequency link while the user is moving within a telephone service area. The radio frequency link establishes a connection to the switching systems of a mobile phone operator, which provides access to the public switched telephone network (PSTN). Modern mobile telephone services use a cellular network architecture and, therefore, mobile telephones are called cellular telephones or cell phones in North America. Mobile phones offering only those capabilities are known as feature phones; mobile phones which offer greatly advanced computing capabilities are referred to as smartphones

4. A mobile phone (also known as a cellular phone, cell phone, and a hand phone) is a phone that can make and receive telephone calls over a radio link while moving around a wide geographic area. It does so by connecting to a cellular network provided by a mobile phone operator, allowing access to the public telephone network. By contrast, a cordless telephone is used only within the short range of a single, private base station In addition to telephony, modem mobile Phones also support a wide variety of other Services such as text messaging, MMS, email, Internet access, short-range wireless communications (infrared, Bluetooth), business applications: gaming and photography. Mobile phones that offer these and more general computing capabilities are referred to as smartphones What is Mobile Phone ?

5. The Evolution of Mobile Phone/History Alexander Graham Bell invented telephone and 1878 he made the first phone call . Motorola introduced some of its first cell phones during the1980s . Those phones were completely different from the devices we have today since from no side they were cost effective and handy. The first Smartphone was developed by IBM & BellSouth which came out to in public in 1993 . These Smartphones are advancing at a very fast pace and are not restricted to just internet browsing or playing games . Now you can do every possible thing with these modern handheld devices.

10. Mobile manufacture and Brands There are several mobile phone manufactures across the globe and each manufacturing company has its own brands depending on the marketing and technological demands. Examples of manufacturing firms and their brands are :-

11. Mobile Phone Generation The history of the wireless communications started with the understanding of magnetic and electric properties observed during the early days by the Chinese, Roman and Greek cultures and experiments carried out in the 17th and 18th centuries. YEAR Description 1880 Hertz-Radio Communication 1897 Marconi- Radio Transmission 1933 FCC (Federal Communication Commission) 1938 FCC rules for regular services 1946 Bell telephone laboratories 52 MHz 1956 FCC - 450MHz (Simplex) 1964 Bell telephone active research 800 MHz 1964 FCC - 450 MHz (Full Duplex) 1969 FCC - 40 MHz bandwidth 1981 FCC? release of cellular land phone in the 40 MHz 1982 At & T divested and Server RBOC (Regional Bell Operation Companies) formed to manage the cellular operation. 1984 Most RBOC market in operations 1986 FCC allocates 5MHz extended band.

This uses 2.4 MHz spectrum.

13. Concept of Mobile network technology A cellular network or mobile network is a communication network where the last link is wireless. The network is distributed over land areas called cells; each served by at least one fixed-location known as base station. This base station provides the cell with the network coverage which can be used for transmission of voice, data and others .

14. The Revolution of Mobile Phone The year 2021 is here, and it also marks the start of a new decade, and a new revolution. Looking back to the decade, we got to see many major changes in the tech industry. We have come a long way in technology. Phone technology is one of them, with much more functions and feature changes. Here are some of the changes that took place in tech during the decade:- 3.5 inch display to 6 inch or above display phones 60 hertz refresh rate to 90/120 hertz refresh rate Battery size Wi-Fi 4 to Wi-Fi 6 Audio jack to no Audio jack Symbian to Android/iOS Bluetooth Single camera to double/triple/quad camera setup Media consumption Social media

15. Mobile Operating System According to Wikipedia A Mobile operating system, also known as a Mobile OS, a Mobile platform, or a Handheld operating system, is the operating system that controls a mobile device similar in principle to an operating system such as Linux or Windows that controls a desktop computer or laptop. LIST OF MOBILE OS Symbian Android iOS RIM BlackBerry OS Windows 7.5 Bada MeeGo (Tizen)

16. Mobile necessary in today's life Cell phones have become a necessity for many people throughout the world. The ability to keep in touch with family, business associates, and access to email are only a few of the reasons for the increasing importance of cell phones. Today's technically advanced cell phones are capable of not only receiving and placing phone calls, but storing data, taking pictures, and can even be used as walkie-talkies, to name just a few of the available options. When cell phones were first introduced to the public, they were bulky, expensive, and some even required a base unit that had to be transported along with the phone. Good reception was a major problem and in general, early cell phones could only be used in certain locations were the signal was particularly strong. As cell phone technology advanced, the difficult in using them became less of a problem. Today , cell phone reception has improved greatly due to the use of satellites and wireless services. As cell phones improved and became simple to use, the importance of cell phones increased accordingly. Cell phones are the perfect way to stay connected with others and provide the user with a sense of security. In the event of emergency, having a cell phone can allow help to reach you quickly and could possibly save lives. However, the importance of cell phones goes way beyond personal safety. Modern cell phones are capable of internet access, sending and receiving photos and files, and some cell phones are equipped with GPS technology, allowing for use in most locations around the world and allowing the cell phone to be found or the user located in the event of loss or emergency.
