1104 == 9.4  Can I use 868Mhz version for 915Mhz bands? ==
1105
1106
1107 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.
