Validated Reference Design Guides

Very High Density 802.11ac Networks Validated Reference Design

Super Contributor II

Very high-density WLANs are defined as RF coverage zones with a large number of wireless clients and APs in a single physical space. For purposes of this reference design, a VHD WLAN is one that is designed to serve at least 100 devices per cell. A VHD WLAN may serve as many as 500 devices per cell. With the proliferation of wireless-enabled personal and enterprise mobile devices, a surprisingly diverse range of facilities need VHD WLAN connectivity:


  • Large meeting rooms
  • Lecture halls and auditoriums
  • Convention center meeting halls
  • Hotel ballrooms
  • Stadiums, arenas, and ballparks
  • Concert halls and amphitheaters
  • Casinos
  • Airport concourses
  • Passenger aircraft and cruise ships
  • Places of worship

To help our customer and partner engineers succeed in meeting these new requirements, we have written this new validated reference design (VRD) exclusively about very high-density (VHD) WLANs. The guide captures the best practices of our field engineering teams. Aruba also built a dedicated VHD test facility with 300 of the latest 802.11ac devices to produce updated performance data. We are releasing this data to the public to assist in capacity planning



Aruba is introducing a new and modular approach with this VRD. We recognize that the people who are interested in this topic have a wide range of knowledge levels and interest levels. To that end, Aruba is publishing this VRD as a series of three guides, plus two individual scenarios that deal with specific deployment use cases. These guides can be mixed and matched as desired based on each reader’s experience and interests. This organization is shown below.

Thank you @clukas and your team for this amazing VRD!


Thanks a lot for the VRD's lot of useful info.


This is one of the best documents I have seen to date on the topic of High Density Wireless! This does a great job of showing all the factors to be considered including Theory, Planning, Engineering and Scenario Plans. This material is very useful regardless of the wireless vendor you are currently using. You do not have to be an Aruba customer to access this information. GREAT JOB Aruba Networks for helping improve the industry for everyone. - Douglas Resseguie

Thanks @DResseguie The team appriciates it! @clukas
