  1. WiMAX: Faster Cheaper Better Honors Project Heather Persons

  2. What is WiMax? • Worldwide Interoperability for Microwave Access • standards-based technology • delivers miles wide wireless broadband access • fixed, nomadic, portable and mobile wireless broadband connectivity without the need for direct line-of-sight with a base

  3. Diagram of Service

  4. The WiMAX forum • organization of more than 400 leading operators, communications component and equipment companies • charter- to promote and certify the compatibility and interoperability of broadband wireless access equipment • established to remove barriers for adoption of Broadband Wireless Access technology • works closely with service providers to ensure that WiMAX Forum Certified™ systems meet both customer and government requirements

  5. Applications • Broadband Access • Indoor or Outdoor Use • Mobile Phone Usage • Sprint Nextel in 2006- investing about $ 3 billion in a WiMAX technology Motorola phone in Bangladesh that uses WiMAX

  6. Comparison to other Technology Comparison of Mobile Internet Access methods

  7. Advantages over Wi-Fi • Wi-Fi • short range (approximately 10's of meters) • suffers from interference in metropolitan areas • access highly contended • has poor upload speeds • WiMAX • no need for direct line of sight provides symmetrical bandwidth over many kilometers • stronger encryption • less interference

  8. Lower Cost • common platform drives down costs with volume opportunity • will use the same modem chipset used in personal computers (PCs) and PDAs • for short distance, indoor self-installable modems will be similar to a cable or DSL • base stations will be able to use the same chipsets developed for low-cost • increased volume will justify investment for higher-level integration of radio frequency chipsets

  9. Wider Coverage • optimized to provide excellent non line of sight (NLOS) coverage • Non Line Of Sight advantages • coverage of wider area • better predictability of coverage • lower cost • fewer base stations and backhaul • simple RF planning • shorter towers and faster CPE install times

  10. Higher Capacity • single carrier modulation schemes with the ability to deliver higher bandwidth efficiency and therefore higher data throughput • more than 1 Mbps downstream and even much higher data rates • increased link reliability for carrier-class operation • possibility to keep 64 QAM modulation at wider distance • possibility to extend full capacity over longer distances

  11. Limitations • Can have high bandwidth, or long distance, but not both at same time • Bandwidth shared between users in same radio section • If there are too many users, internet could be slow.

  12. Conclusion WiMAX is the way of the future. It is more cost-effective, easier to install, and faster than any other option out there.
