Wireless communication combines technology and networking to establish the telecommunication system available today. After WWII ended, the mobile telephone industry was in a good position to transform the US communications. Consumer demand, research facilities and manufacturing capabilities combined to generate the necessary interest for expansion. AT&T and Southern Bell offered the first mobile telephone service in 1946. The first phones used in this system were radio telephones using 150 MHz/ 60 kHz wide. In 1947 the concept for a cellular system was introduced soon followed by the first automated dialing and the invention of the transistor. As the years progressed, so did the cellular frequencies, the quality of production thanks to competition such as Japan, and the invention of the IC chip. By the 1960's companies in the US and in Europe began updating the cellular systems and expanded the coverage. Later in 1969, the Bell System offered the first commercial cellphone system using frequency reuse technology in pay-phone capacity onboard trains along the east coast. With the creation of the briefcase phone and the introduction of microprocessor, the phone gradually became more portable. Motorola offered the first hand-held cell phone by 1973. Expansion was limited until the FCC added a larger spectrum for mobile phone usage. The late seventy's increased the scale of coverage overseas incorporating satellite technology and linking it with other communication systems. With worldwide connections available, compatibility in frequency use or multi-national cell phones evolved but limitations in regulations held the industry back. The mid-1980's and 90's competition in the cell phone industry grew world-wide and began to market more and more consumers in the US where popularity was continually booming. Analog systems held the US from early growth but no for other countries who had few existing telephone companies that could meet the high demands. By adopting a digital standard, the US was on its way to becoming up to date by world standards and this standard included using analog systems as well as digital. More channels and carriers allowed for more users that had a growing number of companies to choose from in the 1990's. Also in the mid 1990's GSM combined computer capabilities into the phone eventually expanding into the internet usage, text messaging, photo sharing, multi-media devices found today.
When historians look at the development of communication, especially telephone communication, the amount of technology produced is overwhelming for such a few decades in time. If it wasn't for the government holding back the development through regulation and slow response in releasing frequency holdings, the US may have been quite different than it is now. While some of the limitations ended up being helpful, it makes a person wonder what we may have missed out on. Perhaps the use of the internet would have had more interest earlier on or radio communication might have been more popular. Either way, the world definitely has become smaller in its virtual mobility and its use of new media has extended into all facets of communication. The creation of multi-use communication devices continues to expand and will penetrate more and more into our daily lives at work, home, school, church, and anywhere else we may go. While integration is the way of the future, we still have to stop and evaluate where the limits of our technology should be. Cell phones have indeed gone under large scale transformations and they continue to evolve to meet the demands of the consumer.
