Find out what is really going on with your WiFi.

Our wireless RF survey services map your entire wireless environment, so you can see exactly where the signal drops, what is causing it, and what it will take to fix. The result is faster, more reliable connectivity in every corner of your space, from the boardroom to the back of the warehouse.

Most businesses only notice their WiFi when it lets them down. A dropped call in a meeting, a tablet that will not connect on the shop floor, a dead spot in the corner office that no one can explain. The causes are usually invisible: interference, poor access point placement, too many devices fighting for the same airtime. A survey makes them visible.

Using Ekahau, the industry-standard survey toolkit, our UK-based engineers measure signal strength, interference, capacity, and coverage across your site, then hand you a clear picture of the problems and a practical plan to resolve them.

What is a Wireless RF Survey?

A wireless RF survey, also known as a wireless site survey, WiFi site survey, or wireless network survey, is a structured assessment of how radio signals behave across your physical space. It measures the things that decide whether your WiFi feels fast and reliable or slow and frustrating: signal strength, interference, access point load, channel overlap, and coverage.

It answers the questions that guesswork cannot. How many access points do you actually need, and where should they go? Why does performance collapse in one part of the building? Will the network cope when a room is full of people and devices, not empty? The output is a detailed report with WiFi heatmaps and clear, prioritised recommendations, so wireless network design becomes a decision based on evidence rather than trial and error.

Is poor WiFi holding your business back?

Modern work runs on wireless. Laptops, phones, video calls, card machines, scanners, building systems, all of it leaning on a network most businesses never think about until it fails. And when it does fail, it rarely announces itself. It shows up as a call that keeps dropping in one meeting room, a checkout that lags at the worst moment, a team that has quietly learned which corners of the office to avoid.

The frustrating part is that most of these problems are invisible and fixable. Weak signal, congestion, interference, and patchy roaming between access points all trace back to a wireless design that no longer matches how the space is actually used. They cost time, test your customers’ patience, and drag on productivity in ways that never quite make it onto anyone’s to-do list. A professional wireless RF survey is how you find the root cause, instead of buying more hardware and hoping.

Which survey do you need?

Not every survey answers the same question. We will recommend the right one for your situation, and often combine them.

Predictive survey

Modelled in software before anything is installed, using your floor plans and the building’s materials to simulate how WiFi will behave. Ideal for new builds, fit-outs, and budgeting, because it tells you how many access points you need and where, before you spend a penny on hardware.

Passive survey

Our engineers walk the site measuring the live RF environment, capturing signal strength, interference, and coverage exactly as your devices experience it. The best way to understand a network you already have and to find the source of dead spots.

Active survey

We connect to the network and measure real performance: throughput, roaming, and packet loss. This is how you confirm the WiFi actually delivers for demanding applications such as voice and video, not just that a signal is present.

Post-installation validation survey

Carried out after installation or changes, to confirm the deployed network matches the design and meets the standard agreed at the start. Proof, not assumption.

What Do Our RF Wireless Survey Services Include?

Every survey is scoped to your site, but most include the following:

– Predictive, passive, and active RF site surveys, chosen and combined to suit whether you are planning, troubleshooting, or validating a network.

– Ekahau heatmaps and signal analysis, turning invisible RF into a clear visual map of exactly where coverage is strong and where it breaks down.

– Spectrum analysis to pinpoint non-WiFi RF interference, the microwaves, Bluetooth, and rogue equipment that standard tools miss but that quietly wreck performance.

– Best-practice wireless network design review, measuring your current or planned layout against how enterprise WiFi should actually be built.

– Access point placement and capacity planning, so high-density spaces are designed for the busy hour and the number of devices in the room, not just for coverage on paper.

– 2.4GHz and 5GHz performance assessment, with WiFi 6E and WiFi 7 readiness, so the design serves you for years rather than dating the moment it is installed.

– Clear remediation and futureproofing recommendations, prioritised so you know what to fix now and what to plan for next.

The tools behind the results

A survey is only as good as the kit and the engineer behind it. We run our surveys on Ekahau, the toolkit trusted by a large share of the world’s biggest enterprises: an Ekahau WiFi survey pairs Ekahau Pro software with the Ekahau Sidekick measurement device to capture accurate, real-world RF data rather than estimates. For RF interference that does not come from WiFi at all, such as microwaves, Bluetooth, or rogue equipment, we run dedicated spectrum analysis.

We design against the access points you already run or plan to buy, modelling vendors including Cisco, Aruba, Meraki, Ruckus, and Juniper Mist, so the recommendations fit your environment rather than forcing a rip-and-replace. Every survey is done with current standards in mind, including WiFi 6, 6E, and WiFi 7, so the design serves you for years, not months.

How our wireless survey works

Our surveys are non-intrusive and scheduled around your operations, so day-to-day work carries on while we gather what we need.

Discovery and requirements

We start by understanding your space, how it is used, the number and type of devices, and the applications that depend on the network, so the survey targets what matters to you.

Floor plan and environment review

We assess your layout and building materials, the quiet but decisive factors in how WiFi behaves.

Predictive design

When you are planning a new or changed network, we model coverage in software first, giving you an access point count and placement plan before any installation.

On-site survey

Our engineers carry out passive and active surveys with Ekahau, capturing the real RF environment and live performance across the site.

Spectrum analysis

We identify non-WiFi interference that standard tools miss, a common and overlooked cause of unreliable wireless.

Analysis and reporting

You receive a clear report: heatmaps, access point placement, capacity findings, and prioritised recommendations, written to be understood by decision-makers as well as IT.

Optional remediation and validation

If you want it, our engineers will implement the fixes and return for a validation survey to prove the result. There is no obligation to use us for the work.

Every office space has its own wireless challenge

Wireless behaves differently in every building. The same access point that performs perfectly in an open office can fall over in a warehouse aisle or a thick-walled Victorian building, because coverage, interference, and capacity are shaped by the space itself. The hard environments are exactly where real expertise earns its place, and they are where we do our best work.

Corporate and high-density offices

Where hundreds of laptops, phones, and video calls compete for the same airtime in open-plan space. Here, the challenge is rarely coverage; it is capacity, and designing for the busy hour rather than the empty room.

Warehouses and logistics

With high racking, moving stock, and large open volumes that scatter and absorb the signal. Consumer-grade WiFi simply cannot hold up to scanners, handhelds, and automated equipment that need a reliable connection on every aisle.

Healthcare and listed buildings

Where thick walls, protected features, and strict clinical requirements rule out a one-size-fits-all design. Careful AP placement and survey work are essential, as our case study below shows.

Retail and hospitality

Where guest WiFi, card payments, and stock systems all share the network, and a dead spot at the till or in a guest room is felt directly in revenue and reviews.

Education

With dense, seasonal usage across large and varied campuses, from lecture halls that fill in minutes to residences that run around the clock. Designs have to flex with very different patterns of demand.

Manufacturing

Where heavy machinery, metal surfaces, and electrical noise create some of the most challenging RF conditions of all, and where downtime on a connected production line carries a real cost.

Why get a Wireless RF Survey From Opticore

UK-based wireless survey expertise, global standards

Headquartered in London with engineers deployed nationwide, we carry out wireless RF surveys the length and breadth of the UK, from single offices to multi-site estates. We understand the realities facing British businesses, and we back that local knowledge with survey methodologies and design standards proven across enterprise networks worldwide. When we hand you a heatmap and a recommendation, it is grounded in your building and held to an international benchmark.

Vendor-agnostic survey design

We do not resell wireless hardware, so our RF survey findings are shaped by your environment and objectives, never by a sales target. Whether your access points are Cisco, Aruba, Meraki, Ruckus, or Juniper Mist, we design around what serves your network best. That independence is precisely what makes a survey worth commissioning: when we say an access point should move, or that you need three rather than six, it is because the data says so.

The right tools, the right engineers

A wireless survey is only as reliable as the kit and the people behind it. Our engineers run industry-standard Ekahau tooling, paired with hands-on RF and spectrum analysis experience, so coverage gaps, interference, and capacity problems are found accurately the first time, not guessed at. Accurate data means a design you can actually trust coming out.

Beyond the survey: 24/7/365 support

A survey captures your wireless at a moment in time, but networks change as people, devices, and layouts move. Through our bespoke OHMP platform, we offer continuous monitoring, analytics, and management, so the performance your survey is designed for is maintained, and new issues are caught as they emerge rather than at the next complaint.

A transparent partnership

No jargon and no black boxes. From the first scoping call to the final survey report, you always know what we are testing, what we have found, and what we recommend, set out in plain language your whole team can act on. You see the value being delivered at every stage.

Wireless Site Survey FAQ

What tools do you use for the RF Survey?

We use industry-leading tools such as Ekahau Sidekick to capture real-time spectrum analysis and performance insights. These professional-grade tools allow us to pinpoint interference, dead spots, and performance gaps accurately, ensuring your wireless design is optimised for speed, coverage, and reliability.

Will the survey disrupt business operations?

No. Our RF surveys are designed to be non-intrusive and carried out around your normal working hours. Passive surveys don’t interfere with live systems, meaning your staff and operations can continue as usual while we gather the data needed to improve your wireless performance.

What are the signs of poor wireless design?

Dead zones, slow connection speeds, dropped VoIP calls, or poor roaming between access points all signal weak or poorly planned Wi-Fi design. These issues affect productivity and user experience, especially in offices, warehouses, or healthcare settings where reliable connectivity is business-critical.

Can you help fix the issues you identify?

Absolutely. Beyond surveys, we provide full remediation planning and implementation. From reconfiguring access points to redesigning wireless layouts, our engineers ensure long-term fixes. We also provide documentation, security recommendations, and performance tuning tailored to your environment.

Do I need a survey if I’m upgrading my office or moving location?

Yes. Any new office build, refurbishment, or major layout change requires a survey to guarantee optimal Wi-Fi coverage. Early planning avoids costly redesigns and ensures your network is ready for modern applications, hybrid working, and future growth.

Can you design wireless for specific use cases like warehouses or hospitals?

Yes. Our engineers specialise in complex environments such as high-density offices, warehouses with heavy machinery, or hospitals with strict compliance needs. Each setting demands tailored design to ensure coverage, roaming, and security meet your industry’s requirements

How often should I conduct an RF survey?

We recommend annual RF surveys to maintain optimal performance, or whenever you make significant changes—such as new layouts, added devices, or infrastructure upgrades. Regular reviews ensure your wireless network adapts to evolving user demands and avoids hidden performance issues.

How much does a wireless RF survey cost?

Cost depends on the size and complexity of the site, the number of floors or buildings, and the type of survey required. A predictive survey is the most economical, while full on-site passive and active surveys involve more engineering time. We scope every job individually and give you a fixed quote after a short discovery call, so there are no surprises.

How long does a survey take?

Most surveys are completed on-site within one to a few days depending on the size of the space, with the report following shortly after. We will give you a clear timeline when we scope the work.

What is the difference between a predictive and an on-site survey?

A predictive survey models your WiFi in software before installation, which is ideal for planning and budgeting. An on-site survey measures the real environment once a space exists, which is more accurate and essential for troubleshooting or validating performance. Many projects use both: predictive to design, on-site to verify.

Do you need our floor plans?

Floor plans make a survey faster and more accurate, particularly for predictive work, but we can work from other drawings or capture the layout ourselves if none are available. We will tell you what we need during scoping.

What do we actually receive at the end?

You receive a clear report containing WiFi heatmaps, an access point placement and capacity plan, identified interference and coverage gaps, and prioritised, practical recommendations. It is written to be understood by your leadership team as well as your IT staff.

Can you survey for WiFi 6E or WiFi 7 readiness?

Yes. We design with current standards in mind and can assess whether your environment and cabling are ready for WiFi 6E and WiFi 7, so any investment you make is futureproofed rather than dated on arrival.

Do you work with our existing wireless vendor?

Yes. We are vendor-agnostic and model leading platforms including Cisco, Aruba, Meraki, Ruckus, and Juniper Mist, so our recommendations build on what you already have wherever that makes sense, rather than forcing a replacement.

What is the difference between coverage and capacity?

Coverage is whether a signal reaches a space. Capacity is whether the network can serve all the devices and demand in that space at once. A room can have a strong signal and still perform poorly if it is not designed for the number of users in it, which is why we assess both.
