Radio Specifications
In open environments with no physical obstructions between the antennas,
the device automatically selects the best data rate for the current radio
connection.
the device automatically selects the best data rate for the current radio
connection.
NOTE:
The range values provide a rule of thumb and may vary according to
the actual radio conditions at the location where the product is
installed. The range of your wireless devices can be affected when:
- Antennas are placed near metal surfaces and solid high-density
materials.
- The radio signal is absorbed by obstacles or objects. E.g. in areas
with floor to ceiling walls, the range can be decreased down to 15%
on its maximum value.
