Channel utilization and interference analysis
Part of WiFi Surveys (Ekahau). Last reviewed October 2026.
Quick answer
What is Channel Utilization and Interference Analysis?
Channel utilization and interference analysis measures how busy each Wi-Fi channel is and what else is transmitting on it. Deploris captures spectrum and Wi-Fi data with a Sidekick-class analyzer, identifies co-channel overlap, adjacent-channel problems, and non-Wi-Fi sources, then delivers a documented channel and power plan to reduce contention.
WHAT THE WORK COVERS
What Channel Utilization and Interference Analysis includes.
- 01Channel utilization percentages per channel and location, split into Wi-Fi traffic and non-Wi-Fi energy
- 02Co-channel and adjacent-channel interference mapping from neighboring APs, including those on other networks
- 03Spectrum analysis to locate non-Wi-Fi sources such as Bluetooth, wireless video, microwave ovens, and DECT phones
- 04Review of existing channel width, DFS channel use, and transmit power settings against what the environment supports
- 05Rogue and neighboring SSID inventory with signal levels and the channels they occupy
- 06A proposed channel, width, and power plan per AP, with the reasoning for each change
HOW WE DELIVER IT
How it is delivered.
- 1
Capture the spectrum
We scan 2.4 GHz, 5 GHz, and 6 GHz where applicable at representative points and at busy times of day, because interference changes with occupancy and shift patterns.
- 2
Map the sources
We separate Wi-Fi contention from non-Wi-Fi interference, locate fixed sources on the floor plan, and record whether they are intermittent or constant.
- 3
Model channel reuse
Using the survey data, we test channel and width combinations, factor in DFS behavior, and aim to minimize co-channel overlap without starving any area of capacity.
- 4
Document the plan
You receive the findings, a per-AP channel and power table, and a note on which changes are safe to apply during hours and which need a window.
INPUTS AND OUTPUTS
What you provide and what you receive.
You provide
- Current controller or cloud dashboard export showing AP names, channels, widths, and power levels
- Busy periods and shift patterns, so we can capture the spectrum when it is under load
- Known equipment that transmits in unlicensed bands, such as cameras, sensors, and cordless phones
- Read-only access to the wireless management platform if you want configuration correlated with findings
You receive
- A channel utilization and interference report with per-area findings and plan markers
- A per-AP table of current versus recommended channel, width, and transmit power
- A list of identified interference sources with locations and suggested handling
- Spectrum captures stored in the Ekahau project file for later comparison
WHEN IT FITS
When this is the right deliverable.
Throughput is poor even though signal strength looks fine, which often points to contention or noise rather than weak coverage.
You are adding access points to a dense floor and need to know whether the channel plan can absorb them.
A neighboring tenant or a new warehouse system has started transmitting in the same bands as your network.
