1. 802.16 :
802.16 is an IEEE standard which defines Wireless Inter-operability for Microwave Access (WiMAX) technology products. It covers all WiMAX series of products. It is optimized for 50 km. It provides the service throughout the coverage area to enable continuous connectivity. This 802.16 standard provides more scalability in usability point of view.
2. 802.11 :
802.11 is an IEEE standard which defines Wireless Local Area Network (WLAN) or WiFi. It covers all WLAN series of products. It is optimized for nearly 100 meters. It does not provide the service throughout the coverage area to enable continuous connectivity. This 802.11 standard provides less scalability in usability point of view.
