first thing to do is to tell me the name of the indicator which is too bad, because I’m a little confused. Ho failure cannot be as high as 95%, and you certainly don’t want it to exceed 95% 🙂
I assume the HO Failure is due to “Radio” ? It might be a problem of clock synchronization. You might need to go on site and re-sync the clock.
Otherwise, double check interference level where those HOs are taking place…
