WiMAX By Arunachalam Courtney Giblin
What is WiMax? High Speed Wireless Broad Coverage
Features of WiMAX • Scalability • Quality of Service • Range • Coverage
WiFi WiMax Channel Bandwidth Maximum Data Rate Maximum bps/Hz • Optimized for indoor performance • No mesh topology support within ratified standards • Optimized for outdoor NLOS performance • Standard supports mesh network topology • Standard supports advanced antenna techniques WiFi 20 MHz 54 Mbps 2.7 bps/Hz WiMAX 1.5 – 20 MHz 100 Mbps 5.0 bps/Hz Why not WiFi Relative Performance Coverage • Scalability • Relative Performance • Quality of Service • Range • Coverage • Security
WiMAX Weaknesses • Lack of high quality spectrum • Few large carriers ready • Lack of volume • No mutual authentication
