Smartphones, tablets and many other electronic devices already charge wirelessly. However, the devices have to be in the direct vicinity of the charger. A breakthrough in this area has now been achieved by the US company Ossia, which has received FCC approval for a new technology for wireless power transmission without distance limits.
Wireless charging, no matter the distance
It sounds like a dream: the wireless charging station for smartphone and co is located in one room, while the devices to be charged can simply continue to be used in another room. What has so far failed due to technical requirements could soon become reality.
The US company Ossia has now achieved a breakthrough with its proprietary charging technology Cota, which has received approval from the FCC (Federal Communications Commission). The approval removes the previous restriction to a maximum distance of one meter and thus realizes – at least theoretically – wireless power transmission without distance limitations.
5 watts charging power
Technically, a maximum charging power of 5 watts can thus currently be realized. Basic requirements for using the charging technology are also a Cota transmitter, as well as a receiver built into the corresponding terminal. The transmitter and receiver communicate with each other 100 times per second to ensure secure energy transmission at all times. This works even when the end device to be charged is in motion.
Archos, Foxconn and T-Mobile are the first partners to work with Ossia to further develop the technology. Thanks to certification by the FCC, the manufacturer is now officially allowed to offer the “Cota Real Wireless Power System” in the US.
EU approval already in place
Approval in 45 countries around the world, including the entire EU region and the UK, has already been achieved, according to the manufacturer, so in theory there should be little standing in the way of a market launch.
With the help of the Cota technology, Ossia not only wants to charge smartphones wirelessly, but also offer the technology in lamps, wearables and other smart home devices. However, it is still unclear when Cota-enabled devices will reach the market and how expensive the wireless charging system will be.
