Except for the right Graphene As we all know, Nokia's research on wireless charging has never stopped. Some netizens have mentioned to Xiaobian before that they hope that mobile phones can be separated from charging devices during wireless charging. It seems that his idea is about to come true. The foreign media reported earlier that Nokia engineers were studying a use of LTE technology: obtaining power through radio base stations.

Engineers can use the Ultra Wide Band antenna to obtain various radio signals from TV stations, radio stations and mobile phone base stations between 500 MHz and 10 GHz. And collect them, activate the electrons inside the power supply through data transmission to obtain electric energy. In short, it is to convert the radio wave signals obtained by mobile phones into mobile phone power.

At present, they have completed the collection technology of 5mW. In the short term, the goal is to increase the collection to 20 milliwatts, which is enough to ensure the call signal access of mobile phones in standby mode for an indefinite period. Of course, this is obviously not enough. After all, the average person needs to consume far more power than 20 milliwatts to make a phone call. The Nokia team hopes to set the ultimate goal at 50 milliwatts, because incoming calls do not always occur through remote Wireless charging Technology can charge your mobile phone slowly. As long as the time is long enough, it can even fully charge your mobile phone, but you need to have enough patience to wait for it to fully charge. In addition, it will take three to five years for the technology of obtaining power through wireless antenna to be put on the market.

Markku Rouvala， A researcher from Nokia Research Center in Cambridge said that for mobile device researchers, wireless charging is not the only direction of research and development. They are also committed to the collection of multiple energy sources, such as coating solar cell materials on the mobile phone shell. As we all know, Nokia has been testing solar charging accessories for its new devices.

it seems NOKIA We should change our previous image and move towards High-tech The direction of the company has developed!
