Advanced troubleshooting & RF spectrum analysis
When the wireless problem outlasts normal troubleshooting.
Most enterprise wireless issues are resolved by a competent internal team. The ones that are not tend to share a pattern: the dashboard looks healthy, signal strength looks fine, APs have been added or moved, vendor support has closed the case — and users still experience drops, stalls, or unusable performance in one area. Those problems are measurement problems. We measure them.
Symptoms this engagement is built for
- Intermittent disconnects with no pattern the team can pin down
- Strong signal, poor throughput — high retries and low PHY/MCS rates
- Sticky clients that hold an AP long past the point of usefulness
- Roaming failures affecting voice, video, scanners, or medical devices
- High channel utilization or airtime consumption with few active clients
- One area, one band, or one client type behaving differently from the rest
What the investigation measures
- Client-side RF: RSSI, SNR, noise floor, and data rates at the point of failure
- Co-channel and adjacent-channel interference (CCI/ACI) and channel plan effects
- Channel utilization, retries, and airtime distribution per radio
- Over-the-air packet capture: association, authentication, roaming, and retransmissions
- RF spectrum analysis for non-Wi-Fi energy and duty-cycle characterisation
- Controller and configuration review: RF profiles, channel width, Tx power, data rates, DFS, 802.11k/v/r
Business impact we work back from
- Frontline staff losing minutes per task to reconnects and stalls
- Scanner, voice, or clinical workflows failing in predictable locations
- Escalations consuming senior IT time with no measured conclusion
- Capital spend proposed to fix a problem nobody has yet characterised
What you receive
- A measured root cause, stated plainly, with the evidence that supports it
- Specific configuration and design recommendations, prioritised
- Captures, spectrum plots, and survey data supporting each finding
- A validation step so the fix is proven rather than assumed
Common questions
When do you need professional RF spectrum analysis?
When performance degrades in a specific area or at specific times and Wi-Fi-side evidence does not explain it: high retries and low PHY rates with few clients, a noise floor well above normal, or a band that performs badly while the other band is fine. A spectrum analyzer shows energy that Wi-Fi adapters and controller dashboards cannot classify, such as video senders, wireless cameras, some lighting and motor controllers, microwave leakage, and certain industrial equipment.
What is the difference between troubleshooting and a wireless assessment?
An assessment characterises the whole environment against requirements. Advanced troubleshooting targets a specific reproducible failure: it starts from the symptom, the location, and the client type, and works down to a measured cause. The two overlap, and a troubleshooting engagement sometimes concludes that the environment needs an assessment or redesign.
What do you need from our team before an engagement?
A clear description of the symptom, where and when it occurs, which clients are affected, the platform and controller version, the RF and SSID configuration, and any recent changes. Site access at the affected location during the hours the problem occurs matters more than anything else.
Can this be done remotely?
Configuration review, controller data, and client telemetry can be reviewed remotely, and that often narrows the cause. Spectrum analysis and over-the-air packet capture require an engineer at the affected location, because they measure what the air actually contains at the point of failure.
