No need to be a network expert to improve your home or office Wi-Fi today! All you need is your MacBook running Mac OS X 10.10+ or any laptop with Windows 7/8/10/11 on board and NetSpot which works over any 802.11 network.

Use NetSpot to visualize, manage, troubleshoot, audit, plan, and deploy your wireless networks.

When working on a Wi-Fi network that will provide an optimal coverage, you'll need a solid research and understanding the radio frequency behavior at the spot. The effective way to obtain this information is a wireless site survey. It will reveal areas of channel interference and dead zones, and will help you tremendously to build a solid network.

The main goal of a WIFI site survey is determining the feasibility of implementing a wireless network in a specific area and finding the best spots for access points and other equipment like cables and antennas. With the help of site survey you will know what type of equipment to get and where to install it.

Wireless Site survey is also an important part of wifi security analysis. NetSpot is a perfect helper for network security specialists in locating and eliminating rogue access points, detecting unauthorized workstations, avoiding cross-channel interference and getting rid of false-positive intrusion alerts. With NetSpot one can also check the security settings (Open, WEP, WPA/WPA2 Personal/Enterprise), non-broadcasting SSIDs and WiFi signal strength. With all this work done well the wireless signal is less likely to spill outside, where a war driver can get their hands on it.

With its advanced collection and visualization of data NetSpot provides its users with a comprehensive and complete WiFi site survey solution.

NetSpot is the easiest native wireless site survey software for Mac and Windows. You need just a few clicks to load your office plan or area map before starting a network site survey. To begin, just point to where you are on the map and NetSpot starts measuring wireless signal right away. You can move around and collect Wi-Fi data of the entire area.

That's it! Now you have all the needed info to analyze radio signal leakages, discover noise sources, map channel usage, locate effective access points, etc.

Visualize Your Wireless Network

Efficiency-wise, your Wi-Fi network needs hotspots placed correctly and wireless channels assigned properly.

The visual Wi-Fi map you get with NetSpot lets you see all dead zones without coverage and optimize hotspots' placements. You can adjust channels' load and decide how to use them better.

Wireless Network Planning

NetSpot is also an amazing wireless survey tool for Wi-Fi planning: load a map, collect some wireless site survey data, and build a comprehensive heatmap of your network.

Now viewing each channel separately is as easy as making a pie. Once you locate an empty channel with no wireless networks – it's the optimal selection for a new Wi-Fi network. NetSpot also lets you easily select channels for new Wi-Fi hotspots with minimal signal-to-noise ratio.
