The telephone, as defined by the Merriam-Webster dictionary, is an instrument for reproducing sounds at a distance. In the process, the sound is converted into electrical impulses for transmission. According to Anderson and Johannesson (2005), the telephone evolved rapidly due to its instant nature. The predecessor of the telephone, the telegraph is hardly present or even heard of today, but the telephone has persisted for more than a hundred years. This is due to the fact that the absence of intermediaries made the two parties easily exchange information in real time without much delay, just by talking on both ends of the line as compared to the telegraph.

For the latter part of the 20th century, the telephone has come a long way. From originally being connected in a wired network, the originally analogue system of transmitting signals in telephone lines became digital, to accommodate more customers. Also, since the data being received and sent are rather bulky, high-speed transmission is important, which needs the digitizing of data being exchanged (Lee, 1997: 3-4). Due to the perceived promise of telephone technology in accommodating and innovating its functions to fit the continuously improving information technology system, it became one of the key elements in the present era of communication.

The mobile phone’s origins can be traced from the mobile two-way radio, which was used in fire trucks and police cars. Soon, mobile telephony for the general public grew, and eventually a system of using transmitters that covered small patches of land that could hand off transmissions as a user moves around became the forerunner of cellular technology (Anderson & Johannesson, 2005:24). Eventually, the use of analogue frequency modulation became replaced by digital telephony, by the introduction of GSM, or Global System for Mobile communications.
