  1. Wireless 802.11n Presentation by Mr David Markland

  2. Wireless 802.11n • Markets • Types of Wireless Solutions • Technology

  3. Typical Markets: CCTV & Security Communications Data & VOIP Wireless Hot Spot Wi-Fi Remote Monitoring

  4. Example of Point to Point

  5. Example of Point to Multi-Point

  6. Example of Mesh

  7. As the tree grows It enters the Fresnel Curve And blocks the Radio Signal Example of Possible Problems

  8. Free Space Vs Non Free Space Visual line of sight Visual line of sight But Fresnel curve blocked Poor Radio Signal Correct line of sight Fresnel curve clear of obstructions Best Radio Signal

  9. 802.11n 5.8GHz Average Radio Speed 300 Mbps Typical Transmission distances of 2 – 60 km Bandwidths of 95Mbps – 1Gbps The Cost / Performance Ratio Not all Radios are the Same!

  10. How is this achieved? 802.11n allowed for development of: • Processors • Antennas • MIMO Technology • Stunning Performance

  11. Stunning High Performance From 802.11n Higher data rates or Longer distance at lower data rates Data Rate Range

  12. Vertical Duplex Signal MIMO Technology Horizontal Duplex Signal MIMO Technology

  13. Radio Network Viewing Software Makes easy Even Easier • Real Time Monitoring • See throughput • Link Quality • See your IP Address • Built in Data tester • Throughput test your links • Test Multiple Data streams • Test TCP, UDP and Multicast modes

  14. Fresnel Examples 2.4Ghz vs 5.8Ghz Mounting Height Examples To accommodate Fresnel Curves
