Leveraging 5.8ghz High Frequency Band, Rf Wireless Charging System Evolves.

Ossia, the developer of radio frequency (RF) wireless charging technology, announced that its Cota wireless charging system can operate in the 5.8GHz's industrial, scientific and medical frequency band (ISM Band) to improve the RF wireless charging efficiency and reduce the size of the transmitter and receiver, and to develop new applications through performance optimization and reduction.

The Ossia founder and Hatem Zeine said that the 5.8GHz wireless charging system not only improves the flexibility of the transmitter and receiver, but also optimizes the directivity of the RF wireless charging technology. He further explained that a higher frequency wireless charging system can accommodate more antennas in the same size transmitter than low frequency systems and increase the power sent to the receiver. In other words, the manufacturer can use 5.8GHz radio wave technology to reduce the size of the transmitter, while providing the same charge as the 2.4GHz system. Power.

In addition, 5.8GHz wireless charging system can support directional wireless power transmission. Because the wavelength of the high frequency radio wave is shorter, the power signal of the high frequency section is more centralized than the low frequency band. It can improve the efficiency and accuracy of the transmission, and make the receiver more power. By taking advantage of the shorter wavelength of HF radio waves, manufacturers can also reduce the size of rechargeable system receivers to suit the size of batteries available today.

Zeine points out that the Cota charging system can charge a number of devices within the transmission range, and even if the device is moving or not in the linear visual communication distance (Line of Sight) of the transmitter, it can still be transferred to power.

Ossia Chief Executive Mario Obeidat says the company is working to reduce the cost of the entire charging system as well as to increase the transmission power of long-distance charging. It is expected that more new applications can be developed by cost reduction, such as the development of Electronic Shelf Labels, or the improvement of existing smart phone rechargeable shells.

The Cota charging system can realize real wireless power transmission without charging plug, wire and charging board. But it may take a while to see the Cota charging system and the smartphones that support it on the market. Previously, Zeine has revealed to the media that its wireless charging product will come out in 2018. Later, however, a spokesman for the company said the time of the product listing would be slightly delayed, and it was expected to launch product prototypes at the end of 2018 or early 2019.
