Wireless Technology

What is Wireless Technology?

The term "wireless" refers, to the communications sent without wires or cables Wireless technology enables the transfer of information between two or more points that are not physically connected. It is irrespective of distances. It encompasses all sorts of wireless technologies and devices, including cellular communications, networking between computers with wireless adapters, and wireless computer accessories. Other examples are radio receivers, satellite television, broadcast television and cordless telephones.

Wireless is a term used to describe telecommunications in which electromagnetic waves (rather than some form of wire) carry the signal over part or all of the communication path. Some monitoring devices, such as intrusion alarms, employ acoustic waves at frequencies above the range of human hearing; these are also sometimes classified as wireless.

Why Wireless Technology

Wireless technology is rapidly evolving, and is playing an increasing role in the lives of people throughout the world. In addition, ever-larger numbers of people are relying on the technology directly or indirectly. So there is huge demand of professionals and freshers in this field. Wireless workers include a wide range of specialties, from the engineers who research needs and design new devices to those who market, sell and service each component.

You can start your career as network engineer or hardware engineer or application engineer

More specialized examples of wireless technology include:

Global System for Mobile Communication (GSM) -- a digital mobile telephone system used in Europe and other parts of the world; the de facto wireless telephone standard in EuropeGeneral Packet Radio Service (GPRS) -- a packet-based wireless communication service that provides continuous connection to the Internet for mobile phone and computer usersEnhanced Data GSM Environment (EDGE) -- a faster version of the Global System for Mobile (GSM) wireless serviceUniversal Mobile Telecommunications System (UMTS) -- a broadband, packet-based system offering a consistent set of services to mobile computer and phone users no matter where they are located in the worldWireless Application Protocol (WAP) -- a set of communication protocols to standardize the way that wireless devices, such as cellular telephones and radio transceivers, can be used for Internet accessi-Mode -- the world's first "smart phone" for Web browsing, first introduced in Japan; provides color and video over telephone sets
