Hi,
Just a quick question when using sandwhich strategy : UMTS900 in between GSM900.
When separation from UMTS carrier to 1st GSM channel is 2.2MHz for example, is there any UMTS adjustment to be done regarding filter.
How to make the NodeB use 4.2MHz, and not 5Mhz? Any Commissioning parameter?
I am asking that for Huawei, and for NSN?
Thanks
