The Wireless Communication Revolution

By Jay Kumar

A Wireless network is by definition a computer network that exists without the use of wires. It is mostly associated with telecommunication networks. These networks transmit information in the form of electromagnetic waves or radio waves which are sent from one device to another.

The wireless technology that exists today has come a long way since it was introduced in the 1980's. 1G stands for first generation technology. This is machine level analog technology. With this technology a voice call is transmitted through radio signals between radio towers. This technology was highly unreliable because of poor voice links. Calls were also susceptible to eavesdropping.

To improve on the shortcomings of 1G technology, 2G technology was developed. This second generation technology relies on digital signals to transmit a voice call to a radio tower. Digital signals allow data to be compressed. This means that more data can be transmitted as compared an analog signal. This technology is most widely used in present times.

The 3G technology is considered by many as the future of technology. It is preferable that the 1G and 2G, because the high-transmission technology, advanced multimedia capabilities and access to a global movement. It is primarily used with devices that combine telephone access. The user must subscribe to the service provider uses this technique.

A Wireless Local Area Network (WLAN) is what connects two or more devices using a wireless distribution method. This is achieved by means of a Wi-Fi router. This Wi-Fi router could also be called a hotspot. This allows users to move around within a certain distance of the Router and still be connected to the network.

Wireless Wide Area Networks (WAN) is a wireless network that covers a large outdoor area. This can be used to connect branches of offices or can be used to connect a large public area. These can be combined with renewable sources of energy so that they can be stand alone systems.

Bluetooth is another wireless technology is open. Allows data transfer within walking distance of the fixed line to mobile devices. It is very popular because it is available in most mobile phones. This can also be used to connect a cell phone to a computer with the same technology.

Wireless modems are also becoming increasingly popular these days. These allow the user to connect to the internet simply by connecting a USB to their computer. They do not require Wi-Fi signal.

There are many Service Providers in the Indian Market that offer Wireless services. Reliance Communications offers these services at very reasonable rates.

Wireless communication is changing-face communication. A revolutionized the way we work. It is also to bring the world everyday.
