A WiFi site survey is one of the most effective ways to improve your network’s performance or plan a new wireless system. It provides detailed, accurate insights into how your WiFi currently performs — and how it could support your organisation more effectively.
Watch our WiFi expert, Lee Wright, explain what a WiFi site survey is and why it matters.
Why a WiFi Site Survey Matters
Before booking a survey, it’s important to understand what happens if you don’t address network issues.
The True Impact of WiFi downtime
If you’re struggling with WiFi downtime or signal dead spots, your organisation is likely losing productivity and revenue. Poor connectivity disrupts processes, impacts users, and frustrates staff, students, or clients who rely on a stable connection.
A weak digital experience can even drive customers to competitors. Many businesses try to fix WiFi problems by adding more access points, but this often leads to overlapping signals and worse performance.
That’s where a professional WiFi site survey can help.
What Does a WiFi Site Survey Include?
A WiFi site survey gives you data-driven insights into how your wireless network performs in real-world conditions. Here’s what it covers:
1. Customised AnalysisEvery site is unique. An on-site survey analyses your building layout, construction materials, and potential interference sources. Engineers then design a network that meets your specific operational needs.
2. Determine Optimal AP Placement
A site survey identifies the best placement for access points (APs) to ensure complete signal coverage. Engineers measure signal strength, noise ratio, and quality at multiple points — even mapping APs from architectural plans when needed.
3. Identifying Interference RisksOther wireless devices, electrical equipment, or neighbouring networks can create interference. During the survey, engineers detect these sources and fine-tune channel selection and configuration to minimise disruption.
4. Network Capacity Planning
A survey assesses how many users and devices your network supports. By analysing bandwidth and usage patterns, engineers recommend the ideal number and configuration of APs — ensuring consistent performance, even under high demand.
5. Performance Analysis & Troubleshooting
Throughput, latency, and packet loss tests reveal bottlenecks or weak spots. Engineers use this data to make adjustments and optimise performance. This also provides a foundation for future network design.

6. Cost Savings
By surveying first, you only buy the equipment you truly need. Fixing issues later is often more expensive and less effective. A survey ensures every hardware and configuration choice is informed by real-world data.
7. Validation of Design
Post-installation validation checks that your network performs as expected. Engineers compare projected vs. actual performance, ensuring 100% coverage and satisfaction with your final setup.
On-Site vs. Remote WiFi Surveys
Only an on-site WiFi survey can guarantee 100% coverage accuracy and a design built for your exact space and budget.
However, if an in-person visit isn’t possible, remote (predictive or passive) surveys can still deliver valuable insights — though they can’t fully account for physical interference factors on site.
Do You Need a WiFi Site Survey?
You may need a WiFi site survey if you are:
-
Installing a new wireless network
-
Experiencing dropouts or slow speeds
-
Upgrading or expanding your existing system
Professional technicians use specialist tools to test every part of your site and recommend improvements. Without a survey, achieving guaranteed coverage and performance is nearly impossible.
WiFi surveys are not one-size-fits-all. Depending on your needs, engineers can:
-
Diagnose and fix existing faults
-
Design a brand-new network
-
Upgrade and future-proof your current setup
