The Aranet system uses frequencies from the ISM radio band. The frequency allocation for this band depends on the region, so Aranet has 5 versions of each product that cover most of the world:
EU868:
Channel 1: 868.10 MHz
Channel 2: 868.30 MHz
Channel 3: 868.50 MHz
US920:
Channel 1: 917.3 MHz
Channel 2: 917.5 MHz
Channel 3: 917.7 MHz
Channel 4: 917.9 MHz
Channel 5: 922.9 MHz
Channel 6: 923.1 MHz
Channel 7: 923.3 MHz
Channel 8: 923.5 MHz
AS923:
Channel 1: 923.1 MHz
Channel 2: 923.3 MHz
JP923:
Channel 1: 923.0 MHz
Channel 2: 923.4 MHz
KR923:
Channel 1: 923.1 MHz
Channel 2: 923.3 MHz
The Aranet system can operate up to 3 km / 1.9 mi in the line-of-sight (LoS) range. Line-of-sight range means that there are no visible obstacles that are in-between the base station and the sensor, e.g. an open field, a large hall.
