Adding more access points is the most expensive way to make a wireless problem worse. We measure what your RF environment is actually doing, then tell you what to change and what to leave alone. Fixed price, written report, no hardware agenda.
Four situations cover almost every enquiry we get. Pick the one that sounds like you and we will tell you what it involves.
There is nothing to measure yet, so we model it. Your floor plans are built into design software with real wall construction, ceiling heights, racking, glazing and attenuation zones applied, then we simulate access point placement, antenna choice, transmit power and channel plan until the design meets the criteria you need.
For anything unusual, heritage stone, tilt-up concrete, cool rooms or dense racking, we bring a live access point to site first and measure actual propagation through the real materials. That calibrates the model so the design reflects your building rather than a generic assumption.
We walk the site capturing every frame in the air, then associate to your network and measure what a real client device actually experiences. That gives us coverage, signal to noise, co-channel interference, channel utilisation, throughput, retries and roaming behaviour across every area, including the ones everyone forgets like stairwells, plant rooms and loading docks.
Alongside that we review the configuration itself: channel and power plan, SSID and band strategy, data rates, firmware and airtime efficiency. In a large share of cases the hardware is fine and the settings are the problem, which is a far cheaper outcome for you.
Installed networks rarely match the design exactly. Access points move to suit cable routes, ceilings turn out differently, and the coverage that was promised is not always the coverage delivered. We survey the finished installation and compare measured performance against the criteria the job was contracted to, area by area.
Where a tender or standard sets its own targets, we survey and report against those rather than ours. The output is independent evidence, not a vendor marking their own homework.
Intermittent faults usually mean something outside the Wi-Fi is involved. Purpose-built spectrum analysis finds non Wi-Fi energy in the band from microwave ovens, cordless devices, video senders, wireless cameras, motor controllers, faulty electrical gear and radar hits on DFS channels. We locate the source rather than just noting that it exists.
Where the spectrum is clean, we capture at frame level and follow the client through association, authentication and roaming. That traces the fault to wherever it truly lives, which is often the client driver, the switch config, the DHCP scope or the RADIUS server rather than the radio at all.
Engage us for one piece or the whole lot. Each is quoted as a fixed price once scope is agreed.
Design work that happens while changes are still cheap.
Floor plans modelled with real construction materials, obstructions and attenuation zones. We simulate AP placement, antenna type, transmit power and channel plan until the design meets your criteria, then hand over marked-up plans and a bill of materials.
A live access point taken to site to measure how signal really behaves through your walls, racking and ceilings. Used to calibrate the predictive model in buildings where assumptions are risky and rework is expensive.
Coverage is the easy half. We size the design around device count, application mix and peak concurrency, so the network holds up when the room is full rather than only when it is empty.
Measuring what is actually in the air and on the wire.
A full walk of the site capturing every frame without joining your network. Produces the true picture of coverage, signal to noise, co-channel interference, channel utilisation and neighbouring networks, per band, per floor.
Associated testing that measures what a client device genuinely gets: achievable throughput, latency, jitter, packet loss, retry rate and authentication time, mapped across the site rather than sampled at one desk.
Not everything in the band is Wi-Fi. We identify non Wi-Fi interference by type, duty cycle and physical location, including radar hits that push you off DFS channels without warning.
Post-installation measurement against the agreed design criteria, area by area, with documented variance. Written to be usable as evidence at practical completion or against a tender specification.
Fixing what is there and proving the fix worked.
An independent review of a network you already own. Controller and AP configuration, channel and power plan, SSID and band strategy, security posture, firmware currency and airtime efficiency, combined with on-site RF data into a prioritised findings list.
For problems that have already beaten everyone else. Frame level capture, association and authentication analysis, roaming decision tracing, and the discipline to follow the fault into the wired network when that is where it lives.
Tuning transmit power, channel width, minimum basic rates, legacy rate removal, SSID rationalisation, band steering and roaming thresholds. Then we survey again, so the improvement is demonstrated rather than claimed.
We do not send you a folder of heat maps and wish you luck. The report answers the questions that led you to call in the first place, with the maps as the evidence behind each answer.
Measured signal strength across every surveyed area and band, showing precisely where the network meets the target and where it falls off, down to the individual room or aisle.
Evidence: signal strength mapsStrong signal sitting on a high noise floor still performs badly. Signal to noise and channel utilisation data separates a coverage problem from a noise or contention problem.
Evidence: SNR and utilisation mapsAchievable physical rate plus measured throughput at points across the site, so the answer is a number from your building rather than a figure off a datasheet.
Evidence: data rate and throughput mapsCo-channel and adjacent channel interference mapping showing where APs share airtime unnecessarily, which is one of the most common causes of a network that got worse after more APs were added.
Evidence: channel overlap mapsCell boundaries, which AP serves each area and how much overlap exists between them. Too little overlap breaks roaming, too much wastes airtime, and both look identical to a user.
Evidence: associated AP and overlap mapsCoverage from the second and third strongest access point at every point, which is the requirement underneath any real time location or asset tracking application.
Evidence: secondary and tertiary coverage mapsSpectrum findings identifying interference by type, duty cycle and where in the building it originates, so it can be removed, relocated or designed around.
Evidence: spectrum analysisA prioritised list in plain English with quick configuration wins separated from work that needs budget, so you can act on Monday without waiting for a capital approval.
Evidence: findings and recommendationsMarked-up plans with positions, models, antennas, mounting method and cable drops, plus a materials schedule where required, so the job can go straight out to quote.
Evidence: AP layout plans and BOMSignal strength is measured in dBm and it is a negative scale, so closer to zero is stronger. Here is roughly what each range supports in practice.
Access points running at full power create oversized cells that overlap, share airtime and stop devices roaming. Turning power down is frequently the fix.
A device can sit at -50 dBm and still crawl if the channel is congested or the noise floor is high. Signal to noise and utilisation matter just as much.
We survey at the height devices are actually used, with a representative adapter. Ceiling height readings on a high gain card flatter the result and mislead everyone.
Which is why the report always pairs signal strength with noise, utilisation, data rate and client behaviour rather than presenting a single colour map on its own.
A survey means nothing without a target to measure against. We agree the criteria with you up front based on what the network has to carry, then report against it line by line. Typical starting points are below, adjusted to suit your devices and environment.
| Application | Primary Signal | Signal to Noise | Coverage Requirement |
|---|---|---|---|
| General data and browsing | -67 dBm or better | 20 dB or better | Single AP coverage |
| Voice and video calling | -65 dBm or better | 25 dB or better | Two APs with overlap for seamless roaming |
| High density areas | -65 dBm or better | 25 dB or better | Capacity driven AP count, controlled cell size |
| Warehouse scanning and handhelds | -65 dBm or better | 25 dB or better | Continuous coverage at device height, aisle by aisle |
| Location services and asset tracking | -75 dBm or better | 20 dB or better | Three or more APs heard at every point |
| Outdoor and yard areas | -70 dBm or better | 20 dB or better | Coverage across defined operational zones |
Where a tender, standard or manufacturer specification sets its own criteria, we survey and report against that instead.
No open ended engagement and no surprise invoice. Most sites go from enquiry to delivered report inside a fortnight.
What the site is, what is going wrong, what devices are on it and what the network has to support. Ten minutes usually tells us which survey type fits.
Areas in scope, design criteria and deliverables confirmed in writing, with a fixed price. You know the cost and the output before anything starts.
Plans modelled, or we attend and survey. Passive work is non-intrusive and runs while you operate. Out of hours and staged access is available where operations demand it.
Measured data is processed into maps, cross checked against the agreed criteria and correlated with the spectrum and configuration findings.
Full written report, heat maps, marked-up plans and a prioritised recommendation list, written to be useful to an engineer and a decision maker at the same time.
We walk your team or your contractor through the findings so they get acted on rather than filed. Implementation and a follow-up re-survey are available if you want them.
Every building type fails in its own particular way. These are the ones we see most, and what makes each one difficult.
Racking that changes with stock levels, metal everywhere, height, and handhelds that never stop moving.
Thick stone and brick, no cable pathways, and strict limits on where anything can be mounted.
Multi-floor roaming, glass partitions, dense meeting rooms and wall to wall video calls.
Guest Wi-Fi, EFTPOS, back of house and crowd density that changes hour by hour.
Clinical devices, nurse call and staff duress systems that cannot tolerate a dropout.
High density classrooms, one to one device programs and load that spikes on the bell.
Machinery noise across the band, segregation requirements and unforgiving uptime expectations.
Concourses, suites, media areas and bowls where capacity matters far more than coverage.
Point to point links, weather, seasonal foliage and coverage across open operational areas.
Temporary coverage, tunnels and structures where the environment changes week to week.
Plenty of providers will sell you access points. Far fewer can tell you where they go and prove it afterwards.
We are not tied to a hardware brand, so the findings do not bend toward whatever we would rather quote. If the gear you own is fit for purpose, the report says exactly that.
The recommendations come from people who install, commission and support wireless for a living, so they account for cable routes, mounting reality, budget and how the site actually operates day to day.
Technical depth where an engineer needs it, and a summary a decision maker can act on without a translator. A report nobody understands is a report nobody uses.
Scope, criteria and deliverables agreed in writing before we start, at a fixed price. No hourly meter running and no expanding engagement.
Heritage stone, tilt-up concrete, live warehouses, tunnels and high density venues. The awkward sites are the interesting ones and they are where a survey pays for itself fastest.
Written to a professional engineering standard and suitable for tender responses, compliance evidence, practical completion and handover to whoever manages the site after you.
It depends on floor area, number of levels, survey type and access requirements. Every survey is quoted as a fixed price once the scope is agreed, so you know the number before we start. Send through your site details and we will come back with a figure.
No. A passive survey is completely non-intrusive and runs while you work normally. Active testing associates to the network but changes nothing on it. For sensitive or busy areas we survey out of hours or in stages to suit you.
On-site time depends on area, complexity and access. A single floor office is often a few hours. Multi-level, industrial or campus sites take longer. Analysis and the written report usually follow within a week of the site visit.
Floor plans in any usable format, site access with an escort where required, credentials for a test SSID if active testing is in scope, and a short brief on the symptoms and the devices in use. If drawings do not exist we can work from what you have or measure up on site.
Yes, and it is a large part of what we do. We assess any vendor's wireless network. You are welcome to engage us purely for the independent findings and hand them to your existing provider to implement.
Not at all. The report stands on its own and is written so any competent installer can act on it. If you would rather we carried out the remediation and re-surveyed to prove the result, we will quote that separately.
New builds and fit-outs start with a predictive design because there is nothing on site to measure. Existing sites with problems need an on-site survey, because the cause is usually something a model cannot predict. Many projects use both: design it, build it, then validate it.
We are based in Adelaide with a presence in Melbourne and work nationally. Regional and interstate sites are fine, and travel is scoped into the quote up front so there are no surprises later.
Tell us about the site and what is going wrong. We will come back with a recommended survey type, exactly what it delivers, and a fixed price.
The more detail you give us, the more accurate the quote.
