Change in 5G networks could increase mobile phone battery life by 50%

Building several small stations instead of one high-power 5G tower to distribute the signal, increase mobile phone battery life by up to 50%. This is the conclusion reached by researchers from the University of California, San Diego, USA. New Scientist this Wednesday (10).

Rethinking the way new mobile internet networks are covered provides many benefits, according to scientists who published a study on the subject last month. In addition to increasing the autonomy of devices, the method increases total energy savings by up to three times by eliminating towers.

To this end, they recommend: a system consisting of several small stations installed on top of poles or buildings Deploying 5G in the region instead of the traditional long-range tower model. The signal of each of these stations will be weaker, but they will form a dense network covering the entire region.

The traditional method transmits weak signals to everyone; Each smartphone sends large data packets using more energy to the tower, which is not always nearby. In the new one, since the devices will be closer to the stations, there will be less signal loss and energy consumption will decrease.

The method does not work on 4G networks

Model that uses small 5G towers instead of a high-power tower Only effective in increasing cell phone battery life when applied to the latest networks. In the study, researchers simulated transfers between stations and phones using 3D models of real cities.

They discovered this Small cell network does not work with 4G due to delays in signal distribution old technologyThis makes high power towers ideal for these networks. The ability to create a denser network by constantly moving from one tower to another in 5G coincides with the developed project.

As highlighted in the article, the system proposed by UC San Diego scientists could improve 5G coverage in urban areas, as well as contribute to sustainability: It also helps operators save moneyExpenses are avoided with large towers.
