802.16: 256 OFDM (vs. 64 OFDM)
3.8 bps/Hz peak data rate; Up to 75 Mbps in a 20 MHz
5 bps/Hz bit rate; 100 Mbps in 20 MHzchannel
2.7 bps/Hz peak data rate; Up to 54 Mbps in 20 MHz channel
Bit rate
802.11: contention-based MAC (CSMA)
802.16: grant request MAC
QoS designed in for voice/ video, differentiated services
No QoS support today -> 802.11e working to standardize
QoS
Only 3 non-overlapping 802.11b channels; 5 for 802.11a
802.16: limited only by available spectrum
Channel b/w is flexible from 1.5 MHz to 20 MHz for both licensed and license exempt bands
Frequency re-use
Enables cell planning for commercial service providers
Channel bandwidth for 20 MHz is fixed
Scalability
802.16: 256 OFDM (vs. 64 OFDM)
Adaptive modulation
802.16 PHY tolerates 10 more multi-path delay spread than 802.11
Technical Explanation
Optimized for outdoor environments (trees, buildings, users spread out over distance)
Standard support for advanced antenna techniques & mesh
Optimized for indoor environmentsCoverage
Optimized for typical cell size of 7-10 km
Up to 50 km range
No “hidden node” problem
Optimized for users within a 100 meter radius
Add access points or high gain antenna for greater coverage
