4. Scalability Quality of Service Range Coverage

5. Scalability Relative Performance Quality of Service Range Coverage Security 5.0 bps/Hz100 Mbps1.5 – 20 MHzWiMAX 2.7 bps/Hz54 Mbps20 MHzWiFi Maximum bps/Hz Maximum Data Rate Channel Bandwidth Relative Performance Optimized for outdoor NLOS performance Standard supports mesh network topology Standard supports advanced antenna techniques Optimized for indoor performance No mesh topology support within ratified standards WiMaxWiFi Coverage

7. Lack of high quality spectrum Few large carriers ready Lack of volume No mutual authentication
