In each case, the idea is to take advantage of the 5G network to power various IoT devices, without any constraints for users. As a result, connected devices could be continuously charged, as long as they are close to a 5G network. — Relaxnews
In Japan, a trial program will soon get underway to test the wireless charging of wearables via the 5G network. The idea is that a very slight electrical charge will automatically recharge nearby Internet of Things (IoT) devices, such as smartwatches or connected headphones. However, legal issues mean it's unlikely that you'll be able to take advantage of this technology anytime soon.
According to Nikkei Asia, Japanese telecom group SoftBank is preparing to test technology that will allow wearables such as smartwatches or connected headphones to recharge in the street without any user intervention. The necessary technology will be directly implemented in the 5G stations deployed by SoftBank. However, a green light from the authorities is needed to launch this real-world trial.
This trial is taking place while SoftBank continues to replace all its 4G antennas with 5G stations - a long-term operation. The experiment involves emitting a very slight electrical charge, of about 1mW – sufficient to charge nearby devices – in the 28GHz high-frequency band used in 5G communication. According to SoftBank, this power, which has a range of about 10 meters, will be completely harmless to health. In time, its range could even be extended to 100 meters.
