Hi,

I am confused shall we take total Tx power (60W = 47.8 dBm) or RS power (21.2 dBm) or sub-carrier power (18.2 dBm) in LTE IBS link budget EIRP calculation per antenna ? I think we should take sub-carrier power but it will make huge difference in the number of RRUs and cost! We have 15 Mhz BW and 60W RRU (SISO). It will be great if anyone having LTE IBS link budget excel sheet and hands on experience can help.

Use RS power for link budget cal

Note normally the weak signal of UMTS and LTE are different

UMTS ,-113 dBm
LTE ,-130 dBm

so the target of EIRP will not same
pls.change you target you will get less RRU
