5G [RF1/FR2] Cell site TX Bandwidth Dimensioning
Above are table prepared for 5G FR1/FR2 along with LTE transport bandwidth dimensioning outcome
Formulae Invole
Peak Cell DL TP_Gbps=(BW*SPE*(1+0.1)*DL Share)/1000 { 0.1 is Overhead}
Average Cell DL TP_Gbps=(BW*SPE*(1+0.1)*DL Share)/1000 { 0.1 is Overhead}
Peak Transport BW_Gbps=Peak Cell DL TP_Gbps+(N-1)*Average Cell DL TP_Gbps { N is no of Cells}
Average Transport BW_Gbps=N*Average Cell DL TP_Gbps{ N is no of Cells}
Note:-
In initial phase of deployement, there are two option to dimention TX bandwidth
1. Cell throughput as above
2. Single user Cell Throughput approx. equal Single User Throughput
So there may be 2 types of operator
Who do not afford for a regressive testing for required capacity
They can user single user throughput as Cell throughput in above formulae to calcultae TX BW requirement
Who wish to design and do proper dimensioning below steps need to take
How many concurrent users can handle by OEM/Operator and what are agreegation of minimum bit rate [DL/UL]
