After I check all DN those issue in w29, I found that 7 of 9 DN didn’t show RRU S/N.
DN those didn’t show S/N are both normal C/L & return C/L.
Per we talked before, KN must control your staff to use RF scan. This is quite a serious problem to us.
Please try to solve this problem ASAP and feedback the solution/progress in our MBR meeting.
