Mobile Computing and Devices
The term Mobile Computing is the use of computing devices while in transit. Mobile Computing is both old and new. This research paper will provide history and a brief source of the origins of mobile computing. This paper will also cover various types of devices used to process and transmit information from remote locations to other remote or fixed locations which is known today as mobile computing. This research will explore the growth of mobile computing devices and consider where this technology may lead us in the future.
The experiment with wireless communications began in 1886. Heinrich Hertz (1854-1894) a professor of physics set up two circuits; the first circuit, containing a small space between the ends, was connected to a high source of voltage. With the voltage remaining high, a spark jumps back and forth across the gap. The second circuit that Heinrich experimented with was a conductor. The conductor was formed into a circle with small gaps between it ends. During this experiment Hertz noticed that when a spark was produced at the first circuit, which was connected to the high voltage, the second circuit, the conductor, also produced a spark. Hertz observed that the sparks were being produced while the circuits were away from each other and there was nothing connecting the circuits. In the event the spark from the first circuit was carried and transited, this allowed the second circuit to receive the signal. The energy from the first circuit was carried to the second circuit by the electromagnetic waves. Hertz proved that electricity can be transmitted in electromagnetic waves that traveled at the speed of light. His experiments led to the development of the wireless telegraph and the radio. His name also became the term used for radio and electrical frequency: hertz (Hz). Guglielmo Marconi
