WIRELESS TECHNOLOGIES

Wireless technologies have made significant progress in recent years, enabling many applications in addition to traditional voice communication with a mobile phone. 3G and transfer of data at high speeds have transformed the mobile telephone services and wireless services.

In this section, we look at the following wireless technologies:

3G:

3G stands for third generation mobile telephony. Mobile phones and equipment using the 3G wireless transmit and receive data much faster than second-generation systems, making possible many features and applications.

LTE super 3G:

Super 3G will be the next major evolution in the field of radio communications networks. Super 3G is a standard being finalized which is part of the future evolution of 3G. It includes a significant increase in the rate of transfer of data and better performance, which is a net progress in the field of mobile broadband.

WiMAX:

WiMAX stands for Worldwide Interoperability for Microwave Access. It is a telecommunications technology aimed at providing long range wireless data, and in various ways.

Wi-Fi:

Wi – Fi, short for Wireless Fidelity, is the term used to denote wireless broadband links over small distances between mobile computing devices such as laptops and the Internet.

Femtocells:

Femtocells are low power access points that allow combining mobile technologies and Internet inside the House. They work similar to a cordless phone.

Bluetooth:

This technology simplifies communication and synchronization between devices, without using cables.

DECT:

DECT stands for Digital Enhanced Cordless Telecommunications, is a common standard for wireless phones. This is a radio technology suited for voice applications, data and applications of networks at home, at work, or in public environments. Many wireless phones used in homes are implementing DECT technology.
