1144 1144  
1145 -
1146 1146  It is possible but the distance will be very short, you can select US915 frequency band in 868Mhz version hardware. It will work but you will see the performance is greatly decreased because the 868Mhz version has an RF filter for band 863~~870Mhz, all other frequencies will have high attenuation.
