Sizing Guide

How many User Experience Insight Sensors do I need to monitor my network?

The number of Sensors you need depends on your environment and monitoring needs. Here are some guidelines which can help you decide how many Sensors is right for you.

General Guidelines

  • Place at least one Sensor in each area that users congregate or use Wi-Fi the most, and in areas with Wi-Fi complaints
  • Place Sensors in areas with Wi-Fi or network performance concerns or complaints
  • Place Sensors in locations that are difficult, time consuming or expensive to reach in person (e.g. remote branches)
  • Place Sensors in any areas with mission-critical equipment connected to Wi-Fi
  • Use at least one Sensor per SSID tested
  • Do not place Sensors in areas with access points that get very little data traffic such as coverage access points on the edge of your building or in less frequented areas (e.g. storage rooms)
  • In large networks with multiple access and aggregation switches, consider placing at least one Sensor per access switch
  • Try not to move Sensors after installation as this invalidates comparisons with historical data. If you plan to move a Sensor to trouble spots in response to user complaints, we recommend keeping a spare Sensor for temporary, tactical deployments
  • Typically, expect a ratio of one Sensor for every six to 24 Access Points
  • When in doubt, start small and add more Sensors over time
  • Speak to a User Experience Insight product expert if you need more information
