Small 5G towers can increase cellphone battery life by 50%

Researchers at the University of California found that building several small 5G towers – instead of one large tower – could increase cell phone battery life by 50%. The team published a study on the discovery, reported by New scientist last Wednesday (10).

Scientists suggest that urban areas should use a system of smaller towers, instead of high-power 5G stations. This is because, as the researchers explain in the study, despite having a weaker signal, a network of small towers consumes less energy and can offer greater coverage of the territory.

The 5G tower strategy would help reduce the carbon footprint

“Such a densification strategy solves two main problems. […] It can potentially save triple the power by avoiding large wireless signal losses due to high range and also lead to a 50% improvement in battery life for smartphones connected in the dense network as a result of being located closer and at a lower height than to the towers.” explains the team in the article.

The scientists used open source software to model transmissions between stations and smartphones in 3D models of real cities. In simulations, the team found that five times as many towers would be needed to achieve the proposed result. However, each of them is expected to be only 15 meters tall and could be mounted on top of street lamps or buildings.

The study also highlights that the system would help reduce a region’s carbon footprint by preventing the population from needing to charge their mobile phones as frequently as in the case of a single 5G tower – which forces the devices to transmit large data packets to reach the network.
