NetSpot is the only professional app for wireless site surveys, Wi-Fi analysis, and troubleshooting on Mac OS X and Windows. It's a FREE Wi-Fi analyzer. 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 on board and NetSpot which works over any 802.11 network.
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.
I use NetSpot for simple, effective network surveying and Wi-Fi planning at home and at my customers sites. NetSpot is a really outstanding piece of software!
