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
