Hi Andreas,
Sorry don’t have any direct experiance on erricson so don’t know the details but for a live network I heard they had a mean value of 103 on the cells. Hope its helpful.
Those experianced with Erricson say that they normally view the indipendent differnece between UL and DL and if its 15dB or above there might be cable swap or such issues.
For motorola we used to see variation of more than 8 max.
