The Mobile Internet Industry - Opportunity Knocking.
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.

Television.
Television as well as radio is based upon the use of radio waves.
In a television system two separate, transmitters are employed - one for the sound channel and the other for the picture channel. Each transmitter has its own antenna. The sound transmitter is frequency modulated and simultaneously transmits the sound which accompanies the image.
The image being televised is received by thetelevision camera, which converts electrical impulses into optical impulses. These electrical impulses are amplified by the video or picture amplifier. After proper amplification the video signal modulates the high-frequency carrier of the television transmitter and is radiated into space by the aerial. The picture carrier is amplitude modulated.
At the television receiver, the picture and audio signals ore picked up simultaneously by a single antenna. Two separate intermediate frequency amplifiers are employed; one-for the picture signal and the other for the sound signal. The sound intermediate frequency signal is demodulated by a detector and, after proper amplification, by the audio amplifier. The sound signal is reproduced by the loud speaker in the usual way. The picture intermediate frequency signal is amplified by several stages and then fed into the video or picture detector, where it is demodulated.
The picture reproducing device is a cathode-ray tube. Itconsists of a glass envelope, a source of electrons or a gun, a control grid for varying the intensity of the electron beam and a screen. The screen is covered with a fluorescent material, which glows when struck by a stream of electrons from, the gun. A colour television has three electron guns - one for each of the primary colours - red, blue and green. They bombard a screen of phosphor dots, arranged in groups of three - one dot for each color.
