Video Blog: High-Density Wi-Fi Design Part 2 – RF Planning

In this video, I explain the key RF principles that you should consider when designing a high-density Wi-Fi network. These include:
  • Leveraging the 5 GHz bands to reduce co-channel interference and increase network capacity
  • Appropriate use of 20 MHz versus 40 MHz channel width
  • Using non-adjacent channels to minimize adjacent channel interference
  • Always performing a pre-deployment site survey
  • Appropriate cell sizing to maintain high data rates for clients while minimizing co-channel interference
  • Ensuring a high quality bi-directional link with clients
  • Leveraging facility obstructions for channel re-use
  • Co-locating APs to increase capacity
  • Alternative AP mounting methods and appropriate use of antennas to achieve desired coverage while minimizing co-channel interference

These principles are covered in more depth in the Aerohive High-Density Wi-Fi Design and Configuration Guide.
