WiMAX – ”The next generation WiFi”
WiMAX (Worldwide Interoperability for Microwave Access) is a telecommunications technology aimed at providing wireless data over long distances in a variety of ways, from point-to-point links to full mobile cellular type access
based on the IEEE 802.16 standard, which is also called WirelessMAN
Components:
Two fixed stations:
SS and BS .
The Communication paths between BS and SS:
Uplink / Downlink .

Internet Connections
Three traditional ways to connect Internet:
1)Dial-up access – It is an Internet connection that will be established by using a modem which act as data transfer medium when user initiates dial up connection.
2)Broadband access -This refers to high-speed data transmission in which a single cable(DSL,cable modem) can carry a large amount of data at once.
3)WiFi access - Wi-Fi refers to wireless networking technology that allows computers and other devices to communicate over a wireless signal.
IEEE 802.16 Specifications
Range - 30-mile (50-km) radius from base station
Speed - 70 megabits per second
Line-of-sight not needed between user and base station
Frequency bands - 2 to 11 GHz and 10 to 66 GHz (licensed and unlicensed bands)
Defines both the MAC and PHY layers and allows multiple PHY-layer specifications.
What is wimax
WIMAX is short for “Worldwide Interoperability for Microwave Access”
->Wimax is technically also known as “IEEE 802.16”
->Wimax is a wireless communications standard designed for creating Metropolitan Area Networks(MANs).It is similar to the wifi standard,but it can broadcast as big as 3,000 square miles.
Architecture of Wimax
A Wimax system consists of two parts:
Wimax reciever:
The reciever could be a small box or PCMCIA card, or they could e built into a laptop the way Wifi access is today.
Wimax tower:
It can provide cover to a very large area as big as 3,000 square miles.
Security of Wimax
Wimax would receive data from the Wimax transmitting base station, probably using encrypted data keys to prevent unauthorized users from stealing access
Application Areas of Wimax
• Education networks
• Banking networks
• Rural &urban Connectivity Solutions
• Video conferences Streaming media
• Cellular backhaul
• Public safety
Features of Wimax
• High capacity
• Wider coverage
• Interoperability
• Cost effective
• Flexible Architecture.
• Portability
Advantages:
1)Best suitable for High mobility areas like travelling in trains.
2)Provides High security.
3)For high definition streaming videos it is the best suitable
4)Only Single Base station can serve hundreds of users.
Disadvantages:
1) Wimax is a very power-consuming technology and requires significant electrical support.
2)Bad weather conditions such as rain could interrupt the signal.
3) High installation.
