A New Wireless Paradigm.
Mobile communication and data communication are two of the fastest growing areas in the communications industry. In particular, mobile data communication, which includes wireless Internet, carries a great deal of momentum. The media is keeping a vigilant eye on the evolution of wireless data, and operators and various kinds of enterprise have put wireless datacom at the top of their strategic agendas.
Wireless data communication combines mobile communication and data communication by giving consumers easy access through mobile phones, pagers, or other wireless devices to relevant information on the Internet and intranets.
Operators see wireless data communication as an opportunity to create innovative services on top of existing networks and investments. Doing so will give them a means of differentiating themselves—for instance, to enhance their business image, reduce churn, attract new subscribers, and increase traffic volume per subscriber.
Enterprises are increasingly looking for ways of increasing employee productivity. Wireless data will enable professionals to access corporate data, such as e-mail, -production status, price lists, and other critical information for doing business while they are away from the office. Specific vertical segments, such as financial institutions, have expressed interest in wireless data as a way of distributing services. In this context, wireless data would improve their overall image and increase the availability of services through a rapidly growing low-cost distribution channel. These needs and initiatives from Ericsson and others, have created "phone browser technologies," such as the wireless application protocol, or WAP.

Telegraphy.
Electricity completely changed communications. Once it was discovered that electric current flows along a wire, it seemed possible that it could be used for messages. As long as two places were connected by a wire electric impulses could be sent along it. It meant that people were able to send messages a long way at great speed. The new way of communication had a lot of advantages and by the end of the 19th century cables were laid all over the world.
Samuel Morse, one of the most famous people in communications, invented a special code, which we call now "the Morse code". He thought of using short and long electric impulses. Combining different sets of impulses he made a code for the whole alphabet, and the numbers from 0 to 9. This code was the easiest and the fastest to transmit.
Later on the necessity aroused to increase the speed of sending messages. People decided to use the fact that current could flow one way round the circuit or the other. A new system called double current working" was worked out According to this system a dash and a dot are impulses of the same length but of different directions.
Then a machine was invented to send typewriter messages over a telegraph circuit. Such machines are called teleprinters or teletypes and use International 5-unit code instead of the Morse code. Each letter or figure is made up of five impulses of electric current, either positive or negative, all letters being the same length in time. A teleprinter has a keyboard and every- time one of the keys on the keyboard is pressed it sends the five impulses that make one letter or figure.
As most modern systems use alternating current, one line can be used to send many messages at the same time. It is possible if each message is sent out at a different frequency. This allows high-speed telegraph communication as well as transmission of written messages.
