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.
Our services
Our experienced team brings specialist knowledge across a wide range of sectors, including warehousing, healthcare, retail and other environments.

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?
During professional wireless site surveys we regularly identify issues including:
Poor Access Point Placement
Access points installed in unsuitable locations often create inconsistent coverage and unnecessary interference.
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
Areas where users experience little or no usable wireless coverage.
Poor Roaming
Insufficient signal prevents reliable application performance.
Co-Channel Interference
Devices remain connected to distant access points rather than transitioning correctly.
Adjacent Channel Interference
Multiple access points operating on the same channel reduce available bandwidth.
Excessive Transmit Power
Overlapping channels create unnecessary contention and reduced throughput.
Sticky Clients
Incorrect power settings often create roaming problems rather than improving coverage.
High Retry Rates
Client devices refuse to roam even when a stronger signal is available.
Capacity Bottlenecks
Too many users competing for the same access point affects speed and reliability.
Bluetooth & Non-WiFi Interference
Nearby wireless technologies can reduce overall network performance.
Lift Shaft Attenuation
Building structures can significantly weaken 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.
