IEEE 802.11nHigh-Throughput Wireless

WHAT IS 802.11n?

– Developed by the IEEE 802.11 Task Group “n” (TGn)

– Enables “High Throughput” wireless networking (100+ Mbps)

– Utilizes MIMO to dramatically increases the range and throughput

– Extends wireless data rates well beyond the 802.11ag limit of 54Mbps

– Designed to support speeds beyond 300Mbps

Grouped into 13 categories

802.11n ENHANCEMENTS

− Category #1: New radio technology basics− Category #2: Creation of new HT format− Category #3: Use of 40 MHz channels, versus 20 MHz used in 802.11abg− Category #4: Aggregation− Category #5: Block Acknowledgement− Category #6: Unique 802.11n specific Greenfield mode added− Category #7: Huge increase in the number of data rates via MCS− Category #8: Space-time block coding− Category #9: Beamforming− Category #10: Link Adaptation, Channel Sounding, and Calibration− Category #11: Backward compatibility and coexistence with 802.11abg− Category #12: New Power Save Mechanisms− Category #13: Multiple radios and antennas used in parallel (MIMO)

Channel Bonding

– Use twice the bandwidth

– Clear Channel Assessment (CCA) checks for legacy devices

– Only 1 non-overlapping 40MHz channel in the 2.4GHz band

– 12 non-overlapping 40MHz channels in the 5GHz band

LEADING THE INNOVATION WAVE

E-MSM460

E-MSM466

Available Now!

Based on IEEE 802.11n Standard

– Uses sounding packets to align an AP’s transmitter with a client’s receiver

– Supports three spatial streams 450Mbps

– Non-proprietary

– Reliable

– Future Proof

– Superior to Antenna-Based Beamforming (Proprietary)• No support for three spatial streams• Suffers from hidden node issues• Won’t support future client chipsets featuring Beamforming
