5G New Radio Technology Can Reduce Network Energy Consumption By Up to 55%


According to ABI Research, global mobile data traffic will reach 1331 exabyte in 2025 from 23 exabyte in 2019, increasing at a six-year Compound Annual Growth Rate (CAGR) of 97%. The large-scale rollout of 5G is taking place globally but operators are finding out that 5G introduces considerable costs and additional energy requirements. Some operators have even announced that they have taken aggressive measures to reduce 5G energy footprint, e.g., switching off 5G massive MIMO units at night to save power. In a recent 5G trial conducted by Vodafone, a new 5G radio provided by Ericsson was shown to reduce network energy consumption by up to 55%. Ericsson later announced a new massive MIMO (AIR 3268), which claimed to be 10% more energy efficient, thus further lower energy consumption. On September 28, 2021, Huawei launched a new massive MIMO Meta-AAU that delivers a 30% reduction in energy consumption. All vendors are currently progressing their massive MIMO product lines, aiming for better performance, cost efficiency, and lower power consumptio…
