The History of Cell Phones By: Jessica Hurst
Before the Cell Phone • The history of the cell phone began all the way back with Samuel Morse. • Morse constructed the first successful electromagnetic telegraph in the United States in 1832, and the Morse code. • The telegraph was the first device to send messages by electricity. • After Morse’s discoveries, many other ideas on how to send messages started to arise. • In 1843, Michael Faraday, a chemist, researched to see if space is able to conduct electricity. • In 1865, Dr. Mahlon Loomis, a dentist, was the first person to communicate through wireless by means of the atmosphere. • Throughout the years, most inventors concentrated on wire line telegraphy, which is suspending wires between poles.
The Birth of the Cell Phone • A man by the name of Martin Cooper was the father of the cellular phone. • In 1947, AT&T and Bell Laboratories discovered the idea of cellular communications. • The first cellular phone to ever be created was called the Motorola Dyna-Tac. • This phone was 9x5x1.75 inches, weighed 2.5 pounds, did not have an displays, had 30 circuit boards, only had 35 minutes of talk time, it took 10 hours to charge, and the only features it included were talking, dialing, and listening. • In 1983, it finally was being sold in the market for a high price of $3,500. • Today, there are more cellular subscribers than wire line phone subscribers in the world.
Cell Phones Today • They include services that allow a customer to personalize their phones, entertain them, and communicate with friends and family. Cell phones today allow a person to communicate not only by voice but by pictures, email, or text messages. • Many of the newest features a cell phones have today are of the following: caller id, call waiting and call hold, conference calling, call forwarding, voicemail with message alert, phone directory, alarm reminder, calculator, automatic call delivery, hands-free speaker phone, roam indicator, message indicator, automatic redial, dialing an emergency number, date book, mobile internet, pictures, games, sounds, AOL instant messenger, speed dialing, one touch dialing, car phone charger, and barring a call.
The Future of Cell Phones • The high-tech market research firm reports that high-speed data access, Wi-Fi functionality, high-quality video cameras, or viewing broadcast TV are just some of the future functionalities that are on the horizon for cell phone users. • Wireless is dominating over the world of technology. • Area codes will eventually lose their importance. If you change your state you will be able to keep your same number. Due to wireless, the lines that separate the area codes into states will be cut. • Reception areas will have to increase to worldwide. The concept of anytime minutes will also no longer exist. • Calling restrictions based on time will no longer exist. • There will be unlimited calling plans with longer contracts. • Through the cell phone, you will be able to access the internet, and store files and documents. • To connect to the internet we will be able to hook up laptops and computers through a cell phone. • There may not be dial-up Internet connection any longer. • You may also be able to interact with home appliances with your cell phone. If you forget to turn on the dishwasher, you can just turn it on with a cell phone while out.
How a Cell Phone Works • Each cell phone has a cellular system. • Each cell has a base station that consists of a tower and a small building containing the radio equipment. This allows widespread frequency reuse across a city so that millions of people can use cell phones concurrently. • All cell phones have special codes. These codes are used to identify the phones owner, phone, and the service provider they use. • When a person turns on their phone, “it listens for a System Identification Code, or SID, on the control channel • The cell phone also transmits a registration request that keeps track of the phones location in a database. • The Mobile Telephone Switching Office gets the call that is calling you and tries to find what cell you are in.
