The benefit is that you still only have one WiFi network and one password. As you move around the home, your device gets data from which ever satellite it is closest to. With loads of devices this makes it so much easier to set-up than other ways of extending the signal that have to be logged onto separately. This much I knew, what I hadn’t anticipated was how far a Mesh network could reach.
A particular challenge in my home is that my office is a good 20 meters from the house. I had tried other ways of extending the WiFi to reach without success. I’d also opted to send Internet down the power cable for a while, but this suffered from interference from other electrical devices.
By placing one Mesh satellite unit in the house and one in the office I’ve had no trouble connecting to the WiFi and getting excellent speeds. As you can see it’s quite a distance.
