Japanese mobile operator SoftBank intends to test the technology of wireless transmission of electricity from points of mobile communication, reports Nikkei Asia, citing its own information. The development will allow wearable devices such as headphones and smartwatches to be charged simply by walking next to the base station. According to Nikkei, SoftBank plans to place the equipment in 5G base stations. Remote charging will initially be tested indoors, with the company hoping to expand it to outdoor stations from 2024.
SoftBank is in the process of upgrading its 4G base stations to 5G. SoftBank expects that to prevent a negative impact on the body, the power will be limited to about 1 mW, and the distance – 10 m.Later, the range is planned to be expanded to about 100 m.In addition to charging wearable devices, the technology can be used to track anti-theft key fobs and work with implants …
Japanese regulations restrict the use of such technologies. However, according to Nikkei, the country’s Ministry of Internal Affairs and Communications is planning to issue a decree allocating multiple frequency bands for wireless charging. The start of commercial application of the technology is scheduled for 2025.
