Farley "Mobile Telephone History"
This week’s article is entitled Mobile Telephone History and was written by Tom Farley, a freelance telecom writer. Farley discusses the importance of the telephone and how it became dynamic and the most important communication tool of our lives. The history of the telephone is discussed first in this article. After World War II, the mobile telephone history began which was in the 1940s. After this war the badly left civilian communication needs were able to be addressed. Telephone and telegraph administrations and private telephone companies worked on providing Americans with landline telephones and services. There were three reasons for this particular movement: 1) the United States was physically intact after the war, 2) Bell Telephone Laboratories had a large group of radio engineers and scientists to use, and 3) the Motorola corporation had grown significantly during World War II. In 1946, Commercial Mobile telephony began and in 1947 the cellular radio concept was published. Bell Laboratories’ D.H. Ring and W.R. Young communicated the true cellular radio system for mobile telephony. All the cellular radio elements were: “a network of small geographical areas called cells, a base station transmitter in each, cell traffic controlled by a central switch, frequencies reused by different cells and so on.” Mobiles may have been invented and used in the early 1940s, but it was only after 1995 when mobiles became low cost, rich in features, and used world wide. In this article, Tom Farley eventually goes on to explain the first commercial cellular radio systems. The Bell System made for the first time, the commercial cellular radio operational in 1969. In this year the first all transistor mobile telephones appeared from a large manufacturer. It was big, bulky and was place in a vehicle. Also, the first commercial portable radiotelephones emerged during this time in the United States. A Scandinavian wide mobile telephone network was planned during the late 1960s and early 1970s by the Nordic Mobile telephone group. This group created a report in 1970 that said an analog cellular network would not be available until 1980. Because of this the Nordic Mobile telephone group decided to just design a conventional, manual mobile telephone system. Year after year, additional mobile telephone systems and networks were continuously made and in competition with each other. Next, Tom Farley discussed the long journey to the analog cellular systems. The Bahrain Telephone company began operating the first commercial cellular telephone system in May, 1978. In July, 1978 Advanced Mobile Phone Service began operating in two cities, Newark, New Jersey and Chicago, Illinois. The next year, 1979, INMARSAT was born. INMARSAT was an international group that fostered and coordinated satellite telephony. The American telephone and telegraph split apart on August 24, 1982. Eventually Europe was introduced to analog cellular system. It was introduced in 1981 when the Nordic Mobile Telephone System started working in Denmark, Sweden, Finland, and Norway. Farley said, “It was the first multinational cellular system” (Farley, p.29). Analog services were used for sending voice and the signaling was done with different tones and data bursts. An interesting fact Farley informed his readers on was that the United States began its first commercial cellular service in Chicago, Illinois on October 12, 1983. The fist handheld cellular phone was the Motorola Dyna-TAC from the year 1983. The only problem with the analog cellular system was that the systems could work fine by themselves but not together. Mobile telephones were not able to operate in other cities besides their own. Planning for an advanced roaming service began in the early 1980s. Tom Farley talks about the rise of GSM and North America going digital next. Europeans saw things differently from the Americans. They decided to create a new technology in a new radio band because their cellular systems were not able to be accommodated by the existing telephone systems. This new creation and service was a cellular radio but fully digital and was called GSM. Later the North American cellular network adopted a digital standard, IS-54 in 1990. IS-54 was capable of converting any of its analog voice channels to digital. Digital services were provided in the places it could operate in and analog where it was not able to. Farley also discussed a new cellular band and systems in America as well as the mid 1990s fundamental change. This meant more wireless channels and carriers were allowed in America. Many different types of mobile phones, handheld computers were introduced which had features like a keyboard, built in calculator and calendar programs. This article by Tom Farley was very interesting to me. It gave me great information concerning the history of the mobile telephone. The mobile telephone is very popular today and has greatly changed since it was first created. More applications and networks now exist than before. This is an example of new media developing from old media. The mobile phone updated its system and allowed a more efficient way for people to communicate with each other. I use a mobile phone every day. I communicate with people through texting or actually talking with them. The mobile telephone has turned into a computer system with the advanced features that have been added to them. Faeben Fulford
