Think of the Internet: 

Think of the Internet Present three possible ways to access Internet Broadband Access The main problem with broad band is that it is expensive and doesn’t reach all areas. Wi-Fi Connection The main problem with Wi-Fi access is that hot spots are very small, so coverage is sparse . Dial Up Connection Internet bandwidth is very sparse in this case.

What is WIMAX ?: 

What is WIMAX ? WiMAX is defined as Worldwide Interoperability for Microwave Access by the WiMAX Forum, formed in June 2001. The new technology promises High speed of broadband service Wireless rather than wired access Broad Coverage

WIMAX IN ALL FORMS OF TELECOMMUNICATIONS: : 

WIMAX IN ALL FORMS OF TELECOMMUNICATIONS:

Typical Working: 

Typical Working WiMAX is a Wide Area Network (WAN) technology. Service providers will deploy a network of towers that will enable access over many miles. Internet access is instantly available anywhere within coverage areas.

Requirements: 

Requirements WiMAX Tower 1) Coverage area of nearly as big as 3000 sq miles. 2) Generally situated on the top of the tall buildings. .,.,mount. WiMAX Subscriber Device 1) Receiver could be a small box or PCMCIA card built in a laptop. 2) It could be a WiMAX wireless modem.

How WiMAX Works ?: 

How WiMAX Works ?

Technologies Used: 

Technologies Used Two key advanced wireless breakthroughs incorporated into the Mobile WIMAX standard Orthogonal Frequency Division Multiple Access (OFDMA) 1) Breaking signal into many pieces to increase spectral efficiency. 2) By diversifying the signal in this way, even if some of the pieces don’t make it through ,the signal can be reconstructed at the other end. Multiple Input/Multiple Output (MIMO) smart antenna technology 1) MIMO uses multiple antennas at both ends of the wireless connection (base station and subscriber device) to enable data to travel along multiple independent paths. 2) For example, a 1x2 configuration refers to a device with 1 Tx (transmit) and 2 Rx (receive) antennas; similarly, 3x3 refers to 3 Tx and 3 Rx antennas .

Security Features: 

Security Features Extensible Authentication Protocol (EAP) Advanced Encryption Standard (AES) Cipher-based Message Authentication Code (CMAC) Hashed Message Authentication Code (HMAC)

Licensed Spectrum: 

Licensed Spectrum Licensed to thrill Spectrum is either licensed or unlicensed. Unlicensed spectrum is open to any users, which raises the possibility of interference from other devices. Wi-Fi networks use unlicensed spectrum. WIMAX service providers use licensed spectrum, which allows exclusive rights to its use for more predictability and stability .

WiMAX/Wi-Fi Synergies: 

WiMAX /Wi-Fi Synergies WiMAX takes your wireless Internet further, but you don’t have to burn any Wi-Fi bridges. WiMAX and Wi-Fi are perfectly compatible companions. Together, they give you an always-best connected experience whether you are in a Wi-Fi or WiMAX coverage area

Word of Caution: 

Word of Caution Certified WiMAX WiMAX Forum Certified means anyone can buy a product or service based on the IEEE 802.16 standard from different companies and be confident that everything will work together.

Future with WiMAX: 

Future with WiMAX Imagine broadband on the go enabled by WiMAX : • Engaging in an epic, multiplayer 3-D battle on a train • Video conferencing from the park • Looking up the nearest local bookstore or getting directions to a restaurant while on the move • Downloading movies while at the soccer field • Staying productive on the road without searching for hotspots This is our future—and WiMAX will deliver it .
