Find out why your Wi-Fi
won't hold up
Coverage, roaming, interference, DFS, capacity or configuration: we measure the existing network, isolate the technical causes and deliver a prioritised remediation plan.
No time to book? Leave your number and we’ll call you back →
- ✓ Real field measurements, correlated with the configuration and the symptoms observed.
- ✓ An RF analysis that is independent of vendors and integrators.
- ✓ Causes identified and ranked, not just a collection of heatmaps.
- ✓ An action plan your IT department, network team or integrator can put to work.
A Wi-Fi problem almost never has a single cause
The audit cross-checks radio, clients, configuration and business context to avoid hasty conclusions.
Coverage & SNR
RSSI, SNR, primary and secondary coverage, weak areas and consistency of the radio cells.
Roaming & mobility
RF continuity, cell levels, client capabilities and 802.11k/v/r mechanisms when used.
Interference & spectrum
RF utilisation, non-Wi-Fi sources, noise, co-channel contention and anomalies visible in the spectrum.
DFS & channel plan
DFS events, channel plan consistency, channel widths, frequency reuse and impact on 5 GHz service.
Capacity & density
Number of clients, available airtime, critical applications and fit between design and real load.
Infrastructure configuration
Transmit powers, RRM/DCA or the vendor's equivalent, 2.4 / 5 / 6 GHz bands, SSIDs, mobility settings and controller data.
Measure, correlate, explain, fix
A useful audit links what happens over the air to what the infrastructure actually does.
Scoping
Symptoms, affected areas, devices, applications, architecture and incident history.
Field measurements
Wi-Fi survey, RF spectrum and targeted tests with Ekahau AI Pro and Ekahau Sidekick 2 on the 2.4 / 5 / 6 GHz bands as required.
Correlation
Measurements analysed against radio settings, events, logs and the controller data available.
Remediation
Prioritised actions: configuration, power, channels, AP placement, capacity or further investigation.
Measurements taken where the network works
Production areas, technical corridors, metal structures: the audit is carried out on site, under real operating conditions, with Ekahau AI Pro and Ekahau Sidekick 2.
The job doesn't stop at the building walls
Streets, façades, vegetation, equipment at height: radio readings and observation of the installations combine to prepare recommendations suited to the site.
The client decides when to roam. The network must give it good reasons to.
A sound diagnosis avoids shortcuts: raising power, adding an access point or enabling a roaming protocol does not automatically solve the problem.
Roaming
We analyse coverage continuity, cell size, power differences, client capabilities and roaming assistance mechanisms. The final behaviour still depends on the client's own algorithm.
Understanding roaming drops →DFS & interference
Spectrum observations are correlated with infrastructure events whenever possible. The aim is to tell a real radar event apart from an interference source, a channel change or another RF symptom.
Understanding DFS events →VoWiFi and mobile communications audit
Coverage that looks adequate does not guarantee stable calls. The analysis takes into account RF continuity, SNR, secondary coverage, cell size, roaming, contention and device capabilities. Measurements are correlated with symptoms to tell a radio, client or infrastructure problem apart.

Measured findings
- Relevant heatmaps and RF observations
- Areas with insufficient coverage or SNR
- Anomalies in channels, channel widths, powers or density
- Findings related to roaming, DFS or interference
Remediation plan
- Actions ranked by priority and impact
- Recommended radio or controller settings
- Any changes to access point placement
- Validation criteria after correction
Three Wi-Fi audits, three environments, concrete decisions
Anonymised case studies from real assignments: figures are rounded and anything that could identify the clients has been removed.
Preparing a Wi-Fi 7 migration at a headquarters
Almost 3,000 m² measured over two floors: coverage of the live network, radio density analysis, DFS and validation of a 5/6 GHz target.
Read the case study →Turning a survey into a migration plan
Several hectares mapped: wide differences between production and logistics, spectrum analysis and a phased Wi-Fi 7 design.
Read the case study →Isolating the real causes of disconnections
A new network across three floors, intermittent drops: field measurements, spectrum, controller logs and AP power correlated before naming a cause.

Nothing is required for the first conversation. When these items exist, they help target the useful measurements more quickly.
- Scaled floor plans and access point locations
- Models of the affected devices and applications
- Areas, times and frequency of the symptoms
- Radio configuration, controller exports and available events
- Recent changes to the infrastructure or the building
Audit of a live network or study before deployment?
Your Wi-Fi already exists and performs poorly
Disconnections, unstable roaming, weak areas, DFS, poor performance or unexplained behaviour: a Wi-Fi audit is the right starting point.
Request an audit →You are preparing a new deployment
New building, refurbishment, AP replacement or migration: start by sizing the network before installation.
See the Wi-Fi coverage study →Business or integrator: an independent diagnosis
You are a business
We audit your network and assess the existing setup objectively, whether it was deployed in-house or by a service provider.
See our services for businesses →You are an integrator or MSP
We step in as expert support on your complex projects, as a subcontractor or under your own brand, within the framework agreed with you.
See our partner programme →Ekahau-certified Wi-Fi expertise
Field measurements and a documented RF methodology, completed by infrastructure analysis when the diagnosis requires it.
Ekahau AI Pro, Ekahau Sidekick 2 and infrastructure analysis
TWN Consulting combines survey, RF spectrum and technical analysis of the network to produce a diagnosis based on measured facts and usable data.
