WLAN Site Survey & Heatmap

WLAN site survey: wireless coverage heatmap on a floor plan

Getting the coverage and performance you expect from a wireless network starts with understanding the environment it will run in. With a WLAN site survey we measure your building’s RF environment, plan the network around your needs and document the whole process.

The result is a wireless network that delivers the coverage you need, capacity for your number of devices, data rates for bandwidth-hungry applications, seamless roaming and QoS.

What you get

  • How many access points you need
  • The right locations for those access points
  • Detailed coverage (heat) maps and data rates
  • Sources and locations of interference
  • Detection of rogue access points
  • Coverage gaps in existing deployments
  • Neighbouring networks and channel usage
  • Planning for a room, a building, a campus or outdoor areas

Our site survey process

  1. We collect floor plans and building-material details to model signal propagation accurately.
  2. We assess any existing access points to minimise additional mounting and cabling work.
  3. We optimise access point locations for coverage and serviceability and confirm them with you in a planning session.
  4. We plan extra capacity for crowded areas and places where critical applications are used.
  5. We address outdoor coverage separately.
  6. We validate predicted coverage and bandwidth with on-site measurements.
  7. We document weak-coverage areas and sources of interference and carry out any additional planning.
  8. We combine predictive and on-site measurements into a single report.

When do you need a WLAN site survey?

A WLAN site survey is the right starting point when you are installing Wi-Fi in a new building, replacing an existing network, or when users complain about dropped connections and slow speeds. In hotels, guest rooms, meeting rooms and outdoor areas need special planning; in offices, busy meeting rooms and shared workspaces do.

When interpreting measurements, we take into account current Wi-Fi generations such as Wi-Fi 6, Wi-Fi 6E and Wi-Fi 7, as defined by the Wi-Fi Alliance, which certifies Wi-Fi products. The aim is a network that will still have enough capacity for the new devices of the coming years.

At the end of the survey we deliver a clear report with heatmaps, recommended access point placement and a channel plan. Whoever carries out the installation, the report is a solid roadmap for putting the right number of devices in the right places.

Our reports can be used to grade existing networks, to produce a bill of materials for a new network, and to guide the cabling crew to new access point locations.
