Although the standby time of smart phones is much longer than that of their use, the device runs out of power when it is in standby. This is sometimes unavoidable, and it will inconvenience us. According to foreign media reports, Nokia is currently studying a new technology based on LTE networks, or will achieve unlimited standby time.
According to Technology Review magazine, Nokia engineers use an "ultra-wide band antenna" to acquire radio signals from TV stations, radio stations, and cell phone base stations with frequencies of 500 MHz to 10,000 MHz. Such technology not only enables data transmission, but also converts radio signals into mobile phone power.
Currently, the amount of electricity that Nokia can achieve is 5 milliwatts, and their short-term goal is 20 milliwatts. The foreign station said that although such acquisitions are insufficient to support mobile phone calls, it is more than enough to maintain the standby status. Nokia's ultimate goal is to collect 50 milliwatts, and as long as the time is long enough, there is no problem filling the phone with battery power.
Nokia has been working hard to develop new energy supply methods for mobile phones. In addition to radio conversion, solar charging technology is also in the company's plan. Infinite standby time sounds tempting, but it takes 3 to 5 years to put it into use.
