How to Perform WiFi Site Survey on Mac
Your Mac is a capable machine, but many of its capabilities are limited by the quality of your internet connection. To improve it, you need to learn how to perform WiFi site surveys on Mac, and here we explain the process using NetSpot WiFi Site Survey for Mac.
The goal of a WiFi site survey is to optimize WiFi coverage by helping you find the best place possible for your WiFi router.
Performing a WiFi Site Survey on Mac
WiFi issues are one of the most common problems Mac users experience, and their computers are seldom to blame. The real culprit is almost always poor WiFi coverage caused by the fact that most people place their router near the closest unused electrical outlet, sometimes hiding it away from view behind a piece of furniture.
Unless the router is so powerful that it can provide sufficient coverage despite poor placement (something not many home routers can do), its less-than-optimal place of installation results in the so-called dead zones, which are areas of signal weakness that can cause slowdowns and connection drops.
Conducting a WiFi site survey can serve as a diagnostic tool to identify these problematic zones and propose actionable solutions. Whether you're dealing with a signal drop, inconsistent speeds, or simply planning a new WiFi setup, a site survey provides you with the data you need.
It maps out signal strength, identifies interference from other devices, and helps you understand the layout of your wireless network. With this information, you can reposition your router, add extenders, or change channels to achieve a robust and reliable WiFi network.
Three main types of WiFi site surveys exist:
- Active surveys: To perform an active survey, you need to be connected to the surveyed network in order to record information about the characteristics and performance of the connection. Active surveys are particularly useful when troubleshooting connectivity issues.
- Passive surveys: This type of WiFi site survey doesn’t require an active connection to any specific WiFi network. Instead, the wireless site survey tool passively listens to all available networks in the area, gathering useful information about them.
- Predictive surveys: As its name suggests, this survey predicts how WiFi signals will likely travel in the surveyed area based on a set of input parameters, such as the location of the WiFi router. Predictive surveys are performed remotely using specialized software applications prior to the actual deployment. Read more about what is a predictive survey.
Combined, the three main types of WiFi site surveys can tell you everything from signal strength, signal-to-noise ratios, and interference to throughput, round-trip time, and packet loss, among other useful information.
Best of all, performing them isn’t nearly as difficult as it may seem at first. You just need to choose the right WiFi site survey tool for Mac and let it do the hard work for you.
WiFi Site Survey Software for Mac
As a Mac user, you can choose from a multitude of WiFi site survey software tools with support for active, passive, and predictive surveys, but you should know that the differences between them can be quite pronounced.
Here are some things you should look for when selecting the best WiFi site survey software for Mac:
- Compatibility: Your WiFi site survey Mac tool of choice should be compatible not just with your Mac computer but also with any 802.11 network.
