13. In the Noise Level field, specify a threshold value for the noise
level.
• High – sets the noise level to -70 dBm. Recommended in
noisy environments.
• Medium – sets the noise leve to -85dBm. Recommended in
most environments.
• Low – sets the noise level to -100 dBm. Recommended in
low-noise environments.
The base radio-modem regularly scans the current operating
frequency to determine the degree of a radio noise/interference on
this frequency. Should the level of noise on the given operating
frequency be greater than the level specified in this field, the
transmitter will take the following measures:
• Stops broadcasting on this frequency
• Switches to the next frequency in the list and performs the
scan on this new frequency.
– If the frequency is clear of noise, the radio-modem will
start using this frequency for data transmission.
– Otherwise, the radio-modem will continue the scan
process throughout the frequency list until the frequency
with an acceptable amount of noise is found.
