Hi Experts we have done refarming on 900 band and are launching 3rd carrier on U900 layer,
I just need to confirm one thing for UARFCN calculation, We are using 4.2Mhz band for U900 with 1 X 200khz channel on both sides to be used as guard band.
The start frequency for 4.2Mhz band is ARFCN 24 and ending is ARFCN 44.
The middle frequency comes out to be 34 ARFCN = 941.8Mhz, to calculate DL UARFCN 941.8-340 = 601.8 X 5 = 3009 UARFCN DL,
I have two questions:
1) While calculating UARFCN we should multiply 601.8 with 5 or 4.2?
2) If we have to multiply by 5 then considering 5 Mhz we have two middle frequencies, 33 & 34 which result in UARFCN DL 3008 & 3009, Which one to use?
With 4.2 Mhz we are using 2 guard band frequencies one 200khz on each side. Guard frequencies ARFCN 23 & 45.
