WiMAX – What is it?
Worldwide Interoperability for Microwave Access
• Wireless metropolitan area networks (MAN) based
• on the IEEE 802.16 standard
• An emerging standard for high-speed, fixed wireless data
• access (point-to multipoint) or point-to-point communication
• Offers last mile service (NLOS) and a peak data rate upto 70 Mbps
• On average a WiMAX base-station installation will likely cover 3-5 Kms PTMP (16 Km P2P)
• WiMAX Forum has more than 356 members to facilitate the
deployment of 802.16 standards by helping to ensure the
compatibility and inter-operability of broadband wireless
access equipment .
• All of today’s leading vendors such as Intel, Motorola,
Samsung, Ericsson are supporting the WiMAX Forum

802.16 Rev E Benefits over 802.16 Rev D
Better Technical Performance
Better building penetration – bigger cells/better performance
Better battery performance for portable applications
Mobility as well as fixed/nomadic
Better Industry Acceptance
Major Market deployments waiting for Rev E
Rev D seen as interim step only
Rev D interoperability certifications slipping
Better Business Performance
Better reuse of spectrum (N=1, vs. no reuse in rev D)
Avoids “throw away” of non-upgradeable Rev D systems
Better support for high value services – VolP, mobility
Support for wide range of access devices – handsets, laptops, PDA’s

Some Spectrum Planning Issues
• WiMAX Profiles
Ensure Operators choose the correct profiles for
the allocated spectrum
• Guard Bands
How much spectrum between neighbors?
• FDD or TDD?
TDD is more spectrally efficient than FDD
