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]
