2nd Generation 802.11n

1,031

Published on

The Wireless Network Edge has finally arrived: Challenges and Solutions 802.11n is now widely adopted, pushing Wi-Fi steadily as the preferred connection method for mobile and not-so-mobile users. As more and more wireless-enabled devices appear on the network, a number of challenges are also appearing around managing wireless bandwidth and carrying the load across the network.

This session will cover existing HP solutions, such as 3 streams MIMO, band steering, beam forming, broadcast filtering, plus upcoming advancements on RF management, unified wired/wireless, and 802.11ac.

  4. 4. IEEE 802.11nHigh-Throughput Wireless
  5. 5. WHAT IS 802.11n?– Developed by the IEEE 802.1 Task Group “n” (TGn) 1– 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
  6. 6. 802.1 ENHANCEMENTS 1nGrouped into 13 categories − 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 802.1 1abg − Category #4: Aggregation − Category #5: Block Acknowledgement − Category #6: Unique 802.1 specific Greenfield mode added 1n − 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 #1 Backward compatibility and coexistence with 802.1 1: 1abg − Category #12: New Power Save Mechanisms − Category #13: Multiple radios and antennas used in parallel (MIMO)
  7. 7. CATEGORY #3: 40 MHZ CHANNELSChannel Bonding– Use twice the bandwidth– Clear Channel Assessment (CCA) 802.11abg 802.11n checks for legacy devices– Only 1 non-overlapping 40MHz channel in the 2.4GHz band 20MHz 40 MHz– 12 non-overlapping 40MHz channels in the 5GHz band
