Description: This attribute is the sum of the upper and lower guard bands for fine ranging in Hz.
What is docsIf31CmtsUsOfdmaChanFineRngGuardband?
Reports, in Hz, the combined width of the upper and lower guardbands reserved for fine ranging on this OFDMA upstream channel. Fine ranging is the precision timing/power adjustment phase of a modem joining the channel, and admins can use this to understand how much spectrum is set aside as a buffer specifically for that ranging process versus regular data transmission.
