band have been calibrated, users can click
to skip the process; if the band never been calibrated,
users click
in the step of MU Calibration and RU Calibration, software can still procede to the next
step of MU and RU setup, but the system gain will be a little deviation with 20dB, so the final output power
will be not same with the target DL output power.
NOTE2: If there are more than one same band access to MU, then each access need to be calibrated in
MU Calibration step, while in RU Cablibration step, users only need to calibrate the band one time,
because all the same band shares the same PA.
