Today, the possibilities of accessing the Internet by a user are limited to three categories:
- Dial-up access (a modem that connects to the Internet via telephone line with a small access speed)
- Access via WiFi (Wireless Fidelity “- wireless connection from anywhere in a room in which there is a WiFi router for a limited distance)
Access via Broadband (cable broadband connection, high speed, using the telephone line or network cable)
IEEE or Institute in Electrical and Electronic Engineers is an international non-profit professional type that defines the standards, publish articles and lectures in the field of advancement in electronics and electrical technology. This organization has over 365,000 members in over 150 countries. If a working electronic equipment (implementation, testing, applications used) after a standard IEEE 802.16 for example, then it is approved as a device that supports WiMAX and other equipment can be interconnected with the same label.
WiMAX has been developed by the IEEE in several stages since the early 80s and should culminate in 802.16m (WiMAX 2.0) in the near future. Initially wanted to work with broadband technologies frequencies above 11 GHz, but the 2-11 GHz range was introduced, to use diffraction, and work in environments with obstacles, not only in space. The most popular sections are of the 802.16d standard for fixed terminals, and 802.16e, for mobile terminals. Frequencies that are used in consumer equipment, and are already licensed in some countries are 2.5 GHz, 3.5 GHz and 5 GHz.
Demand for wireless networks has grown…[ad_2]
