802.16 vs. 802.11

802.16 vs. 802.11The Institute of Electrical and Electronics Engineers (IEEE) 802.16 protocol is currently the dominant protocol suite for broadband wireless networking equipment used in public deployments. 802.16 is IP, not Ethernet, allowing longer distances than the more widely known 802.11 wireless LAN.

802.11 wireless LAN802.16 has a range of up to several kilometers. 802.16 allows for the strict reservation of bandwidth and QoS. 802.16 uses polling and not the contention access method found in 802.11. 802.16 allows for automatic adaption of radio operating parameters to meet changing traffic loads and interference levels.

The 802.16 protocol suite includes several millimeter microwave frequency secondary standards.

  • 10GHz to 66GHz – 802.16
  • 2GHz to 11GHz – 802.16a

A mobility standard is in the works – 802.16e

802.16 equipment is certified for interoperability by WiMax (Worldwide Interoperability for Microwave Access). So far only a handful of pre-standard products are available and WiMax has not certified any 802.16 products.
