What is WiMAX ?
WiMAX is a wireless digital communications system, also known as IEEE 802.16, that is intended for wireless “metropolitan area networks”.
WiMAX stands for Worldwide Interoperability for Microwave Access. WiMAX can provide broadband wireless access (BWA) up to 30 miles (50 km) for fixed stations, and 3 – 10 miles (5 – 15 km) for mobile stations. It was approved by the IEEE in December 2005, which specifies the Orthogonal Frequency Division Multiple Access (OFDMA) air interface and provides support for mobility.
In contrast, the WiFi/802.11 wireless local area network standard is limited in most cases to only 100 – 300 feet (30 – 100m).
FEATURES:
1)WiMAX technology providess higher speed connection up to 70 Mbps over the area of 30 miles.
2)There is no need for line of sight connection between subscriber terminals and the base station in WiMAX technology and it can support hundreds of subscribers from a single base station.
3)It is also supports low latency applications such as voice, video, and Internet access at the same time.
ADVANTAGES
1)The primary advantages of the WiMAX standard are to enable the adoption of advanced radio features in a uniform fashion.
2)It also reduces the costs for all of the radios made by companies, who are part of the WiMAX Forum™
DISADVANTAGES
There are chances of some of the following threats in WiMAX technology:
1)Authentication
2)Encryption
3)Availability
