To send a Wi-Fi signal from your home to a cellar room approximately 150 meters away, you can use the NanoStation Loco M2 as a point-to-point bridge. However, since the cellar room only has power sockets, you would need to ensure that the receiving end also has a power source for the device.

The NanoStation Loco M2 operates on a single Ethernet port, so connecting two devices directly to receive the Wi-Fi signal in the cellar room would require additional networking equipment, such as a switch, to expand connectivity.

For optimal performance, ensure line-of-sight between the devices and consider environmental factors that might affect signal strength.
