My favorite features, ones that I have used continuously almost every single day, are the Link-Live Cloud Service and the AirMapper Site Survey. The latter is absolutely essential to almost every business I go to. I move around the building and mark where I've been and then, when I get back to my desk, the information is on the dashboard, showing me exactly where devices are. I can see, "Okay, here are printers that shouldn't be there," and I can relocate them better. Or I can check whether the WiFi signal is strong at a given spot and whether I need another access point. The AirMapper Site Survey app is one of the biggest highlights of this product. When somebody asks me, "Why should I use this device?" it's the first thing I show them, and they usually love it. Its ability to gather WiFi site survey data is absolutely amazing. You can collect so many different things including using its spectrum analyzer. You can also use the directional antenna and other features to detect the WiFi signal, its strength and where things are at. If devices are having an issue, you can figure out the cause. Maybe it is behind a wall that is not allowing WiFi signals and you can determine, "Hey, I need another access point here to get my users the internet coverage they need." The AirMapper Site Survey Heat Maps were one of the first things that I used the device for. I wanted to see the WiFi signals, where everything was at, and what was the most used. That was able to help me determine that I needed a new access point inside our center for demos. We were getting a lot of drops there and I figured out that the coverage was not good. We had to get a replacement access point. Overall, the EtherScope nXG is easy to use for less skilled staff but it has deep diagnostics for experts. I had no experience when I first received this device. I had no training and, in less than a week, I was fully proficient with it. When I really wanted to do a deep dive and figure out everything about it through the Link-Live Cloud Service, I had so much data. It made my life a lot easier.
