Hi Pix,
thanks for the repsonse. There is a site at the border and using SFH. All frequencies in SFH are interfered by neighbour country including BCCHs. They have three operators and after drive test measurement we found that only 6 or 7 frequencies are clean, all others are interfered. We wanted to change from SFH to NH in only one cell toward the village at the border (people there experiencing bad quality), that’s the cause why I have asked that in previous post even if I had doubt mixing different hopping type. And we changed all cells in NH yesterday, let’s see after we check KPI and after drive test measurements. We’ll try BBH too and compare results against NH.
Thanks again,
BR,
Rex
