Paul Ben Ishai: The Green Dilemma of 5G Densification

...."The average power consumption of the 3G base station with 3 active antennas is about 1.5 kW [10].  About the same as a coffee maker (although you won’t run a coffee maker 24 hours a day!). 4G sites typically need about 6 kW [11], or 2 electric heater fans, and 5G sites need 3 times that much at 18 kW !!! That is a lot of heater fans, or maybe an electric boiler.

 So lets do a back-of-the-envelope calculation for our neighbourhood in Austin, Texas.  We had 29 4G sites for complete coverage.  That meant a power consumption of 29×6= 174 kW  !!  That is a massive amount.  But we need 100 sites for 5G and each station is 18 kW not 6 kW.

That means our new 5G network is going to need 1800 kW, or an increase of 1000 %  !!!

So, who is planning for this massive jump in power consumption?  No one.  Not in Austin, Texas and not in Jerusalem, Israel."

With all the expectations and the investment, 5G is “actually exaggerated,” and it is not something that the societies need anyway, according to the man who leads a company that dominates the technology.
"In fact, human societies do not have an urgent need for 5G," said Huawei's founder and CEO, Ren Zhengfei, "What people need now is broadband, and the main content of 5G is not broadband."
