Specialists Research Unit of the Finnish Nokia Corporation in Cambridge, uk have developed a prototype system of charging a mobile phone that works on the energy surrounding the radio. Obtained energy, according to developers, it is sufficient to operate the unit in standby mode. The charging system includes two simple electrical circuits and antenna. Receiver circuit and an antenna designed to work with a wide radio band – from 500 MHz to 10 GHz. The components of the system spends more on its work less energy than they receive. Currently, they are able to convert the energy of electromagnetic radio waves into electrical power up to five milliwatts. In the future, may increase power to 20 milliwatts, but it would still be insufficient to make calls.
According to one of the developers, Marrku Ruvala (Markku Rouvala), is not excluded that the power system could be increased up to 50 milliwatts, which is enough for a leisurely recharge the battery. In this case, the phone does not need to be connected to the mains. Features of Nokia from other similar solutions is that it work in a wide range of frequencies, allowing to collect small amounts of energy from radio waves for various purposes. Currently on the radio is powered RFID-equipment detector radios and other devices. It is expected that buy nokia mobile phone with a new feature charging from the radio broadcast will be three – five years. first phones will appear in three – five years. Without a doubt, that copies of these phones from China will have later Several months after the release of the originals and then each online shop nokia phones will fill your page with these devices. Besides the acquisition of phone nokia nokia shop via the Internet has become a very practical and affordable way.
