How wireless charging will power your smartphone through the air

 

Imagine that never connect the smart phone to recharge. Imagine a world in which you are sitting in a restaurant, wandering around the airport, on the plane or at your desk, and your phone is automatically refilled. No more AC Jack, USB-cable, charger, no more batteries.

No wireless power charging at this time. Qi (pronounced "Chee") Now, finally, all the major brands of smart phones. But Qi wireless power of the "near field": battery wiring device simply replace the pillow.

The next generation of wireless power works as a radio and Wi-Fi, a transmission power, as if the device was powered by air. Up to 5 W, also known as a "snack" enough to feed your smartphone or other small battery device, transmitting a transmitter connected to the CA of about 10 meters or 30 feet away. Power received at the receiver based on a chip built into or attached to a battery device.

Loading multiple devices simultaneously, track switches and devices, even if they move (s must be in the exact place), the load elements need only power and knows it stops as soon as the device is fully charged.

Wireless power transmitters may be independent devices or integrated into existing products that are already connected to AC power. Superior light can be a transmitter, and an intelligent LED lamps, TV bezel or desktop PC and intelligent speaker. The first beneficiaries are likely to be the case smart phone or keys. In the end, they will be built in the devices.

Sounds like utopia, right? Maybe, except that the wireless transmission of electricity, which will begin to be called "air force" does not develop as Wi-Fi and Bluetooth is to support independent bands and objective standards such as IEEE. There are at least four companies created by the owner, and, most importantly, the ecosystem of wireless power transmission. Some systems operate via radio frequency (RF) is similar to Wi-Fi. Others use infrared (IR) as a remote control, or even ultrasound, each of which has its own pros and cons. For example, a wireless infrared transmission power and ultrasound work through the line of sight, which means that they can not charge the device tucked in your pocket or bag, around corners or behind walls. It is not comfortable.

radical changes

The basic principles of air power back to Nikola Tesla and Michael Faraday and James Clerk Maxwell in the middle of the eighteenth century. Today, it is likely that this new attention to a change in AirPower, how to interact with all the devices in your life.

One day, their attitude fortunately collect their toys transition from active to passive. Of course, to charge a smartphone from almost dead Air Force Takes 2:58 several times for as much as possible to be connected to an electrical outlet. However, the smartphone is charged with air conditioning in the theory of all time, and this means that it is unlikely that your smartphone has been running out of juice: never again worry about the level of your smartphone battery.

 

DITITO for the next generation of remote AV-Powered AV Control, Bluetooth headsets, speakers, keyboard, smart - hours and group fitness, intelligent locks, security cameras Wi-Fi sensors, door / window, and all the equipment under the battery consumption. Always they have juice. And it's not hard to imagine a future in which some of the AC power to the device, such as a toaster or printers include the power cord as a last resort.

It's safe?

How safe are these power circuit overhead? First, check out this photo Tesla sat quietly in a room full of all sorts of extravagant electric charges. Look? Electricity in the air did not seem to cause problems Tesla. In addition, the energy of the air system on the basis of the Russian Federation operates substantially the same as Wi-Fi.

Despite the fact that it is difficult to absolutely guarantee that there will be no pain, note that all suppliers in the United States Air Force. UU. They should get FCC or FDA approval for RF and IR FORCE, respectively, certificates
