I have a Mikrotik HAP ac2 (very happy with it) which will be connected by Ethernet cable to a shed which is about 5m x 10m in size. I want to add an access point in the shed which provides wifi only inside the shed (one room) and up to about 10m radious outside the shed would be ok. I’m trying to avoid the wifi being available in a house which is about 15-20m away form the shed.
What would be the right choice from the Mikrotik range for this use case?
I’m guessing I’ll need to set the device to 5Ghz only and reduce transmission power?
You can use whatever device with WiFi you like and can afford. Select according to WiFi radios, their channels and antenna types used in it. You just will reduce the power on WiFi using higher antenna gain value while in regulatory domain mode to restrict the interference.
With ease. Remove config, set WiFi, create bridge with administrative mac address of port 1, put all interfaces in it ,dhcp client on it and you have it. Just use non overlapping channels and the same security profiles.
