Wireless Surveys

Wireless Site Surveys

Wireless site surveys (also known as wireless network site surveys or WiFi surveys) are comprehensive assessments of a location to plan and optimise a wireless network. In simple terms, it’s like creating a blueprint for your WiFi network before or even after installation to ensure strong, reliable coverage everywhere.

By measuring signal strengths, mapping out coverage, and identifying sources of interference, a wireless site survey provides the data needed to design a WiFi network that meets your organisation’s needs for coverage, capacity, and performance

Benefits of Wireless Site Surveys

  • No More Dead Zones: The survey measures WiFi signal strength throughout the premises to ensure there are no “dead zones” – areas with little or no signal.

  • Reduced Interference: A survey identifies sources of wireless interference (for example, other WiFi networks, machinery, cordless phones, or microwave ovens).

  • Optimal Coverage & Capacity: By understanding the layout and usage, the survey helps determine the right number of APs and the best placement to cover the area and handle the number of users/devices.

  • Performance and Reliability: Overall, a proper site survey leads to a network that delivers consistent, fast connectivity.

All installations are carried out by certified, DBS checked engineers with experience across business, education, healthcare, and industrial sectors.

How is a Wireless Site Survey Conducted?

First, requirements and building floor plans are reviewed to understand coverage goals, user numbers and specific performance needs such as video calls or scanners.

Next, an on site walkthrough is carried out using specialised WiFi survey equipment to measure signal strength, interference and physical obstacles throughout the building.

The collected data is then analysed using software to create heatmaps showing signal quality. From these results, a detailed WiFi network design is created, specifying the optimal number, placement and configuration of access points to provide full coverage and reliable performance.

Ekahau Wireless Site Survey Tool

One of the most advanced tools we rely on is the Ekahau WiFi survey system, which has become the global standard for WiFi planning and design.

Using Ekahau Pro software together with the Ekahau Sidekick; a portable, high precision WiFi scanner; our engineers can walk through your building and instantly capture detailed data on signal strength.

This technology allows us to generate accurate heatmaps that show exactly where your wireless network is strong and where it needs improvement.

By using advanced survey tools like Ekahau, we are able to speed up the survey process, improve accuracy, and deliver a network design that works exactly as intended.

Wireless Site Survey FAQs

Performing a site survey before deploying a wireless network is important to avoid the common pitfalls of WiFi installation. It ensures you have a proper plan rather than guessing. By surveying first, you’ll discover any building features or radio interference that would hinder WiFi signals. This means you can strategically place your access points to cover the entire area without dead zones and choose channels that minimise interference.

The two main objectives of a wireless site survey are straightforward:

1. Ensure Sufficient RF Coverage: Verify that all required areas in the facility receive a strong and usable WiFi signal. The survey maps out signal strength across the site to reveal any weak spots or “dead zones” that need attention, so they can be addressed in the network design (e.g. by adding or repositioning an access point).

2. Identify Interference and Optimal Placement: Detect sources of wireless interference or obstacles in the environment and determine the best locations for access point installation. By understanding where interference (from neighbouring networks, electronic devices, thick walls, etc.) is an issue, the survey helps place equipment in spots where it can perform best and avoid problem areas.

There are three main types of wireless site surveys:

Passive Survey: The engineer uses scanning tools to detect all WiFi signals in the area without connecting to any network. This method identifies existing signal strength, coverage, and interference.

Active Survey: The engineer connects to the WiFi network and measures real world performance such as speed, latency, and reliability while walking through the site.

Predictive Survey: Using floor plans and software, the engineer simulates WiFi coverage virtually before installation. This helps design the network, which can later be verified on site.

The duration of a wireless site survey depends largely on the size of the site and its complexity. In general, a survey of a small office (say, a few rooms or a single floor) can be done in just a few hours. For instance, a building with a couple of floors and a handful of rooms might take around 3–4 hours to survey. This includes walking the site, taking measurements, and later analysis time. On the other hand, a large facility such as an extensive office building, hospital, large school, or warehouse can take much longer. A large warehouse or multi storey building might require a full day of surveying (6–8 hours or more). Extremely large or complex environments could even stretch over multiple days, especially if detailed active surveys are needed in addition to passive measurements.

A wireless site survey should be performed by a qualified IT professional or wireless network engineer who has experience with WiFi deployments. Ideally, this person or team will have specialised training or certification in wireless networking and access to professional survey tools (like spectrum analysers and WiFi survey software such as Ekahau).
