The 5G Dilemma: More Base Stations, More Antennas—Less Energy?
According to recent research, the ultra-lean design that 5G networks are capable of will make it possible to put more components to sleep for a longer time, reducing energy
As a result, there are many more hardware components per base station. Björnson believes this will probably increase the total energy consumption of 5G base stations compared to 4G. But as massive MIMO technology develops, its energy efficiency may also improve over time.
The explosive growth of mobile data traffic has resulted in a significant increase in the energy consumption of 5G base stations (BSs).
According to recent research, the ultra-lean design that 5G networks are capable of will make it possible to put more components to sleep for a longer time, reducing energy consumption by almost 10 times compared to current systems when there are no users.
1. Introduction 5G base station (BS), as an important electrical load, has been growing rapidly in the number and density to cope with the exponential growth of mobile data traffic . It is predicted that by 2025, there will be about 13.1 million BSs in the world, and the BS energy consumption will reach 200 billion kWh .
