Mobile telecommunications involves transmitting and receiving information using a mobile device. It allows for point-to-point or point-to-multipoint transmissions using digital or digitized analog signals. Cellular technology uses base stations and satellites to spread the signal. Different generations of technology have evolved, with each being able to crack the protocols of previous generations. Mobile telecommunications can help developing countries leapfrog technological levels.
Mobile telecommunications is the process of sending, transmitting and receiving information over a distance for the purpose of communicating. This form of signal transmission occurs with the assistance of some sort of mobile device, such as a cell phone, computer, or other wired or wireless device. The main advantage of mobile telecommunications is the ability to perform point-to-point or point-to-multipoint transmissions using a digital or digitized analog signal. Basic broadcasting uses a number of protocols to send chunks or packets of information.
The various protocols used in mobile telecommunications require specific actions taken at certain times in order for two devices to connect and receive information. Each of these protocols takes the form of a physical layer, which is transmitted in a specific way and finally decrypted by the receiving device. This includes time-varying patterns and space-varying quantities. Depending on the generation of technology used, these protocols take different forms, with each successive generation being able to crack the protocols of previous generations.
Cellular technology makes the most notable use of mobile telecommunications technology. The concept uses a series of base stations, an earth structure or tower designed to propagate the signal from one location to another, and satellite technology. This allows the technology to spread to further locations, providing services to those in a country. Mobile cellular telecommunications began in the late 1970s, evolving over the years in terms of public access, cost and quality.
The first generation technology primarily uses analog telecommunication standards, enabling point-to-point telephone communication. The second generation, launched in the 1980s in Europe, is capable of transmitting higher quality digital signals, including voice, basic messaging and low-speed data connections. Adaptations to technology in the 1990s allowed for higher data rates. The major advancement of the third generation in the late 1990s is the ability for individual users to always stay connected with mobile technology, even when on the go. This advancement allows users to use telephony, video and broadband in a fully mobile environment at higher data rates.
One of the great advantages of mobile telecommunications is the ability of developing countries to leapfrog the technological levels already present in developed countries. For example, while the United States, Europe and Asia have well-established networks of analog telephone technology using wires, much of the Middle East and Africa do not. This means that instead of installing antiquated cable technology across the country in these areas, they can simply install new mobile telecommunication devices and immediately start using better communications.
