WIRELESS AND MOBILE

Wireless and mobile technology allows you to access the Internet from wherever you are. 

You no longer have to be at home or in the office to check your email or browse the net. 

With wireless technology, you can get connected with anyone from anywhere.

WIRELESS AND MOBILE COMMUNICATION

Wireless is a term used to describe telecommunications that use electromagnetic waves rather than some form of wire to carry signal over part or the entire communication path.

It refers to communication without cables or cords, but which chiefly uses radio frequency and infrared waves. This method of communication relies on low-powered radio waves to transmit data between devices.

 

Wireless and mobile communications rely on IrDA
and the wireless networking of computers.

Wireless

Wireless is a term used to describe telecommunications that use electromagnetic waves rather than some form of wire to carry signal over part or the entire communication path.

Telecommunication

The science of information transport using wire, radio, optical, or electromagnetic channels to transmit and receive signals for voice or data communications.

Electromagnetic Waves

A wave produced by the interaction of time-varying electric and magnetic fields.

Radio Frequency

Frequency of electromagnetic waves used for radio and television broadcasting.

Infrared Wave

Electromagnetic waves in the frequency range just below visible light corresponding to radiated heat. IR waves are often used for remote controls.

IrDA

Infrared Data Association (IrDA) is an organisation that defines the infrared communications protocol. A protocol used by many laptops and mobile cellular phones to exchange data at short ranges.

WIRELESS TECHNOLOGY

Wireless technology is rapidly evolving, and is playing an increasingly important role in the lives of people throughout the world. An ever-larger number of people are relying on this technology both directly and indirectly.

Specialised and exotic examples of wireless communications and control include:

• Global System for Mobile Communication
• General Packet Radio Service
• Enhanced Data GSM Environment
• Universal Mobile Telecommunications System
• Wireless Application Protocol
• i-Mode

GSM

Global System for Mobile Communications (GSM) is a globally accepted standard for digital cellular communications system.

i-Mode

The Packet-based service for mobile phones offered by Japan's leader in
wireless technology, NTT DoCoMo
