Can I measure noise level or SNR using mDot?

Some of my places have a very high noise level, my program set the lbt's threshold at -80 dBm. When my mDot want to join the network, it will always say the channel is busy. Can I use mDot to measure noise level or SNR? I want to find out the suitable lbt's threshold.

Question relating to:

The MultiConnect® mDot™ offers significantly longer range and improved radio performance compared to traditional wireless solutions—resulting in greater transmission range and reduced capital expense.
