WiFi Surveys & Wireless Site Surveys
Eliminate WiFi dead spots, improve roaming and optimise wireless performance with professional WiFi surveys designed around your environment.
Our certified wireless engineers deliver accurate survey data and insights for new deployments, troubleshooting and network validation across the UK and internationally.
What is a WiFi Survey?
A WiFi survey is a detailed assessment of your wireless environment, designed to identify coverage gaps, interference and performance issues affecting connectivity.
Poor WiFi is often caused by incorrect access point placement, excessive overlap or poor channel planning rather than insufficient hardware. A professional survey identifies these issues and provides the data needed to optimise your network.

Firstly, just want to say what a positive experience we had with your field engineer last week. He was professional and very accommodating. Overall, we’ve been very impressed with DTE.
Why businesses need professional WiFi Surveys
Poor WiFi doesn’t just cause frustration; it can disrupt productivity, operations and customer service. From dropped Teams calls to unreliable scanners and warehouse devices, consistent connectivity is essential.
For over two decades, we’ve delivered professional wireless site surveys across warehouses, distribution centres, manufacturing, healthcare, education, offices, hospitality, retail, stadiums and airports.

Enterprise wireless technology
Ekahau AI Pro enables our engineers to accurately assess, design and optimise enterprise wireless networks using detailed RF data, heatmaps and performance analysis.
Combined with our practical engineering experience, this allows us to deliver technically accurate, commercially realistic recommendations.
Do you experience these challenges?
Poor Access Point Placement
Incorrectly positioned access points often create inconsistent coverage and unnecessary overlap. We identify the optimum locations for reliable coverage and efficient roaming.
Wi-Fi Dead Spots
Areas with little or no usable signal prevent users from connecting reliably. We identify these locations and recommend improvements.
Coverage Holes
Weak coverage may not cause complete disconnection but often results in poor application performance and slow roaming.
Poor Roaming
Devices remain connected to distant access points instead of moving to stronger signals, causing dropped calls and interrupted sessions.
Co-Channel Interference
Multiple access points sharing the same channel reduce available airtime and overall performance.
Adjacent Channel Interference
Improper channel planning causes overlapping frequencies and unnecessary contention.
Excessive Transmit Power
Higher transmit power isn’t always better. Incorrect power settings often reduce roaming performance and increase interference.
Sticky Clients
Some devices continue communicating with distant access points even when better options exist nearby.
High Retry Rates
Frequent retransmissions increase latency and reduce throughput for all users.
Capacity Bottlenecks
High-density environments require careful wireless design to ensure sufficient capacity for users and devices.
Warehouse Shadowing
Metal racking and stored goods create complex RF reflections that require specialist survey techniques.
Lift Shaft Attenuation
Concrete cores, lift shafts and service risers frequently block wireless signals between floors.
What your WiFi Survey report entails
Following your WiFi survey, you’ll receive a detailed report showing how your wireless network performs, where issues exist and what improvements are recommended.
From coverage heatmaps and interference analysis to access point recommendations, we provide clear, practical insights to help you improve performance, coverage and reliability.

FAQ
Costs vary depending on site size, complexity, and survey type. Contact us for a tailored quotation.
Most surveys are completed within one day, although larger sites may require additional time.
Passive surveys analyse wireless signals, while active surveys connect to the network and test real-world performance.
Yes. Professional surveys can identify interference from neighbouring networks, equipment, and other RF sources.
In most business environments, a survey significantly improves deployment quality and reduces future performance issues.
We recommend surveying whenever major building changes, wireless upgrades, or performance issues occur.
