If we look at the present day to the modern ways of communication to the Internet, we find that there is more than one way, there is a broadband connection, broadband access, which depends on a DSL or a cable modem, and there is a Wi-Fi which depends on the wireless connection with Internet service providers, there is also a dial-up connection, which is still used in other ways.

        But the  most sophisticated and reliable is the WiMAX system, and this word is short for the term Worldwide Interoperability for Microwave Access, also known as 802.16. WiMAX is new system for a fast internet connection and will replace the cable system and the system of the DSL to connect to the Internet from anywhere and without wires

.

Features of the WiMAX

** Provide high speed through the central stations without the need for an area of ​​direct or straight line between sender and receiver

 Not affected by buildings or natural barriers between the central transmitters and receivers. WiMAX technology enables the exchange of media (information, voice, image) between users at high speeds of up to 280 Mbps 280 Mbps
.
 WiMAX technology is designed to give high speeds in all environments, whether the transmitters and receivers on the direction of direct or indirect guidance. The link distance between the transmitter and receiver up to 70 miles at speeds of up to 70 Mbps in a single transmission channel

 The system (WiMAX) consists of two components

1- WiMAX tower is similar to the mobile tower. The tower provides rang 8,000 km square
2- The receiver of WiMAX can be a small box or located inside the (laptop) as found in today's devices

Purification of (WiMAX) work the same principle of technology (WiFi) which you send data from one device to another via radio waves (Radio) and computers

It sends fast waves up to 70 megabytes per second, regardless of the number of beneficiaries and an area of ​​50 km Unlike Wi-Fi, which does not exceed 54 megabit per second to one beneficiary and an area of ​​30 meters
