I was wondering if its possible to create mesh network of WiFi for relatively large area? I am talking about the size of small village (~20km2). The idea is to use centralized connectivity with enough bandwith, then distribute them using mesh wifi router (like Google WiFi) for every X radius

Is this a pipe dream? What would likely be the obstacles?

Mesh-type should be used to maintain just single SSID over a whole network

Google Wifi: We recommend a maximum of five Wifi points in a single mesh set up

Edit: I am just not aware if there's any limit for this case to happen, and why Google Wifi even have that 5 limit value while theoretically to my knowledge, as long as it's placed nearby to each other, wouldn't it could be used to expand the signal unlimited time? I just couldn't find answer elsewhere. Any input is highly appreciated

  • $\begingroup$ It is widely discouraged to use unlimited hops since each hop closer to the source will have more traffic, and since you are talking about 20km2 that’s going to be a lot of traffic. Ubiquiti does have some solutions, like point to point beam transmittors. Try demo.ui.com and choose outlets at castle rock as site. There might be other capable brands but I’m familliar with unifi and am pretty sure there’s a solution to be found there. $\endgroup$ – Ananas_hoi Dec 23 '20 at 8:59
  • $\begingroup$ @Ananas_hoi "since each hop closer to the source will have more traffic" could elaborate this? Since it'll be distributed evenly throughout the area - not sure if traffic become any issue here as long as sufficient plan is used $\endgroup$ – gijoe Dec 23 '20 at 10:02
  • $\begingroup$ How does the signal get back to the centralized connectivity - does it go from wi-fi to wi-fi to wi-fi, or does it go from wi-fi to cable and then get all the way back using the cable? $\endgroup$ – user253751 Dec 23 '20 at 21:59
  • $\begingroup$ @gijoe if I have time tomorrow I will see if I can draw something for you, that illustrates it. However, I think more than enough resources exist online that cover this subject. $\endgroup$ – Ananas_hoi Dec 23 '20 at 23:18
