Why does 5g base station consume so much
5G base stations use high power consumption and high RF signals, which require more signal processing for digital and
That's almost a threefold increase compared to 4G (5). One 5G base station is estimated to consume about as much power as 73 households (6), and 3x as much as the previous generation of base stations (5), (7).
“5G is here, and while the expansion of this connectivity continues and the benefits of an energy conscious, future-proof portfolio are evident, it's simply not enough on its own just to dramatically reduce energy consumption for entire mobile networks. We cannot continue with a 'business as usual' approach.”
The Small Cell Forum predicts the installed base of small cells to reach 70.2 million in 2025 and the total installed base of 5G or multimode small cells in 2025 to be 13.1 million. “A 5G base station is generally expected to consume roughly three times as much power as a 4G base station.
Simulation results reveal that more than 50% of the energy is consumed by the computation power at 5G small cell BS's. Moreover, the computation power of 5G small cell BS can approach 800 watt when the massive MIMO (e.g., 128 antennas) is deployed to transmit high volume traffic.
