What is WIMAX? What is WIMAX? It is a technological development to Wi-Fi networks, where it can transfer larger amounts of information for long distances by using a large frequency bands of radio waves. 

How it works? How it works? Tower. Receiver with antenna. Radio waves.

Benefits of WIMAX Benefits of WIMAX 1) High speeds in all environments ( 70 miles, speeds up to 70 Mbps) 2) Exchange media (information, voice, image, 280 Mbps) 3) Standardized, same frequency equipment should work together

Disadvantages of using WIMAX 1)  Bad Weather Weather conditions (rain) could interrupt the signal. 2)  Wireless equipments wireless equipment could cause interference. 3)  Multiplied frequencies are used.

Disadvantages 4)  Power consuming It requires strong electrical support. 5)  Expensive network  Big installation and operational coast. 6) Lack of Quality Same tower - heavy traffic - it is very hard to maintain high quality

Particular uses of WIMAX Practical uses Particular uses of WIMAX 1) Providing portable mobile broadband connectivity across cities through a variety of devices. 2) Providing a wireless alternative to cable and DSL for "last mile" broadband access. 3) Providing data, telecommunications (VoIP) and IPTV services (triple play). 4) Providing a source of Internet connectivity. 5) Smart grids and metering.
