INTRODUCTION TO MOBILE PHONES Wireless communication has come a long way since weighing around 1.1 kg in 1983 to the myriad of smartphones available in the market today that are lightweight and loaded with endless features. But it all began towards the 20th century, when telegraph and radio technology were evolving tremendously. The transatlantic telegraph was built by 1866. An affinity towards wireless communication was growing for a number of reasons: (i) Increased mobility. (ii) No wiring. (iii) Remote access. (iv) Innovative solution. (v) Defence strategies. The concept of mobile phones is based on a very sophisticated radio. Mobile phones have power-run transmitters in them. This power is supplied by a battery. A low power phone requires smaller battery that allows use of hand-held sets, which are not overly bulky. Transmitters convert voice/sound into electrical signals sent over a frequency spectrum that are received at the station and converted back to the original
Mobile phones have improved a lot since it was first introduced and now nearly everyone owns a mobile phone. It keeps you connected with friends, family and co-workers. This is very good in case of an emergency you can quickly contact someone for help and keeps you safe. A mobile phone is packed with so much technology such as a music player, digital camera and even a GPS.
The telegraph quickly became popular between people that wanted to send messages over long distances easier and faster than ever before. The telegraph also improved ways of communicating across continents. The first telegraph line was laid across the Atlantic Ocean in 1866; later in 1940 40 lines were laid across the Atlantic Ocean. History.com also states that:
The first cell phone was created by Martin Cooper on April 3rd, 1973. Cell phones are radio receivers and transmitters that use electromagnetic energy to send and receive information. Energy travels in waves. The distance from one wave to the next is the wavelength. Frequency is the amount of times the wave oscillates up and down per second. The higher the frequency, the more energy. Frequency is measured in Hertz. One Hz is one wavelength per second. Different electronical things are operated at different rates of hertz. At this point, the fastest connection runs at a 2.1 GHz (gigahertz) range-- that’s 2.1 billion wavelengths per second. Cell phones use low radiation called radio frequency (RF). A cell phone sends and receives
Mobile phones are one of the phenomenal technological advancement of this generation and have changed the way people interact. You can call, send text messages, read emails, play games as well as read and edit documents on the go. People rely on mobile phones as part and parcel of their lives which they cannot live without.
Mobile phones: Is wireless device that allows users to make calls, send text messages and send emails (with the smartphones). As JKJ, it is a state agent mobile phone is needed to be in touch with their customers and colleagues from outside the offices, such as calling the customers from the properties they need to rent or sell.
A mobile phone (also known as a cellular phone, cell phone, and a hand phone) is a device 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.
The age of electric telegraphed information came into picture in the late 1800’s when the first Trans-Atlantic cable was laid. The basic elements of Morse code were used. “Mr. Watson, come here, I want you.” These were the first words spoken by Alexander Graham Bell while working with his invention, the telephone. The wireless telegraph was a major breakthrough in the development of broadcast communication (Holzmann and Pehrson, 2015).
In the 20th century, Gugliemo Marconi, a young Italian, invented the wireless telegraph by using the sources that were investigated by major scientists on electromagnetic waves and electricity. The first audio was sent out by Reginald A. Fessenden in 1907 and by 1910, the wireless telegraph had become what we now called the “radio”. The radio impacted the American society both culturally and politically in the year of 1920s and onward by providing the entertainment and also the comforts that was needed due to the Great Depression.
May 24, 1844, Samuel F.B Morse sent the first telegraphic message. The first telegraph message was sent from Washington, D.C to Baltimore, Maryland. By 1866 the telegraph line was across the Atlantic Ocean sending messages for the U.S to Europe. The telegraph revolutionized long-distance communication, it worked by transmitting electrical signals over a wire laid between stations (1). Samuel Morse also developed a code called Morse code, Morse code transmitted complex messages across the telegraph line.
Cell phones operate with radio frequencies, the cell phones use a lot from the waves
A mobile phone works on a unique networked system which needs no wiring, no fixation and no botheration. Originally it was used in cars, airlines, and passenger trains but increasingly it is becoming ubiquitous. It is basically low- power radio telephone. In this magical system calls go through radio transmitters that are located within small geographical unit which are known as cells. Since each cell's signals are too weak to interfere with those of other cells operating on the same frequencies and more channels can be used than would be possible with high power radio frequency transmission. Narrow-band frequency modulation (FM) is the most common mode of transmission, each message is assigned a carrier, unique to the cell from which it is transmitted.
Now days, the smartphones which are coming are small in size and light in weight which makes it very easy to carry them. You don’t need to sit beside the receiver as your mobile phone is not attached with anything. People say mobiles made life miserable by providing unlimited connectivity but they don’t understand the fact they also provide limited connectivity like you can switch off the mobile phones. Mobile proved life saver for human being in many areas related to human health. Mobile proved boon for business as well as where crucial information is at reach for corporate decisions. Mobile phones made life easy for people who are going to distant area for expeditions to be in touch with rest of the
At Motorola, the Enterprise Roadmap Management System (ERMS) uses roadmaps for product and process innovations for mobile telecommunication technology [2]. Sandia makes multi-dimensional assessment of strategic, social, political and ethical issues for process, product and technology innovations. Road mapping is vastly used for commercializing of technology innovation. National Nanotechnology Initiative (NNI) is helping many entrepreneurs to use this emerging technology [2]. Any company which wants to invest in innovation effectively aligns and integrates its vision and resources to gain competitive advantage using road mapping.
Cell phones are becoming a modern day necessity, to the point that they are a must have for every teenager and adult. Human beings are growing increasingly attached to these devices, depending on them more and more for their communication with other people, job duties, and other daily activities that they must accomplish.
1. The Smartphone industry is a well established market and the threats of a new entrant is low, as technology needed to rival the devices already available is quite advance if they want to differentiate from them
