What is a Wireless Spectrum Analysis?

In the WiFi world, when we refer to wireless spectrum analysis, we refer to the detailed examination of the 802.11 radio frequencies. Most WiFi networks in productions environments use the 2.4 GHz and 5 GHz bands. With the introduction of 802.11 ax standards, also known as WiFi 6, the 6 GHz radio band is also available for utilization. To answer the main question, will performing a WiFi spectrum analysis help your network performance? The answer is no. However, it will provide helpful information in the WiFi network’s planning, troubleshooting, and administration. A WiFi spectrum analysis is analogous to an MRI, an MRI creates detailed images of the body structure. In the same way, a WiFi spectrum analysis also creates detailed pictures of the WiFi spectrum, and the information is used to understand the WiFi performance and diagnose connection issues.

As business WiFi installation services experts, we perform a spectrum analysis for every Wireless Installation Service or WiFi troubleshooting service. WiFi radio waves are saturated with WiFi and non-WiFi devices utilizing the same radio signal channels for communication, sometimes the WiFi traffic is so much that Access Points use non-standard, overlapping channels for communication. The interference caused by machinery and other devices bleeding EMI into the WiFi spectrum adds to the already existing WiFi traffic.

Wireless Spectrum Analysis is one of the main tasks during the wireless assessment. It also becomes a wireless management and troubleshooting tool for administrators to perform regularly after complete WiFi implementation.

 Wireless Spectrum Analysis is useful for:

  • Identifying Wireless Interference: Many devices are using the radio frequency other than WiFi devices. Wireless cameras, security sensors, badge readers, and even EMI from machinery can cause the saturation of the wireless spectrum that manifests as low throughput and unreliable performance, even when the connection between the clients and the access point seems to be strong. Performing a spectrum analysis allows you to identify if WiFi or non WiFi devices are radio interference in your network.
  • Locating the source of the interference: Identifying if radio interference is affecting your WiFi network is one thing, identifying the source of the interference is another. When we perform business WiFi installation services we include the spectrum analysis as part of the service with the goal of identifying the source of the inference so we can use that information for proper WiFi planning.
  • Identify non-WiFi radio activity: This is one of my favorite reasons to perform a spectrum analysis, and it’s usually overlooked during the WiFi design and troubleshooting process. This is relevant in places like factories, warehouses, and distribution centers where many types of machinery and malfunctioning electrical equipment can bleed EMI into the WiFi network.

  • Determine Channel Utilization: Whether your deployment is for a single or dual-band, you want to see the average channel utilization and noise floor for your environment.

As you can see, a WiFi spectrum Analysis is essential in the planning, deployment, and support of WiFi networks. Having a clear picture of the radio bands, channel utilization, and overall wireless interference helps you design a reliable WiFi solution and focus your time and effort in the right places.
