This is possible because the connected devices are in the same IP range and can communicate with each other. Just bear in mind that the WLAN range is not really large and if several devices use the router at the same time, it can happen that communication suddenly becomes slow. I have been using this device from Huawei for a long time and am basically satisfied with it. When I use it intensively, I sometimes have to switch it off and on again. A WLAN router with an external WLAN antenna would probably be a better choice for you, especially if you have a large hut.
