Long-distance air charging technology using RF (Radio Frequency) is one of the key solutions for ESG management or carbon neutral solutions, and it is an innovative technology that can be applied as an eco-friendly solution for companies.
WARP Solution develops commercialization technology for the first time in the world, develops non-contact air charging applications over various distances, and achieves commercialization through application and verification. Recently, it is expected to be used as a charging method for sensors for sensing various types of deep underground sewage pipes, and it can also be applied as a core technology of soldiers’ warrior platform.
Frequency (RF) method non-contact wireless charging technology principle
Mobile communication data, such as images and text, travels on electromagnetic waves. Mobile phones leave only data and discard power. Frequency (RF) type non-contact wireless charging is the principle of collecting only power from electromagnetic waves and using it for charging.
Therefore, a transmitter capable of transmitting frequencies from a short distance (within 1M) to a long distance (several KM) and a receiver that receives frequencies and converts them into electricity can be used to charge various electrical devices.
Necessity of air charging technology
The wireless charging method using the principle of magnetic induction and charging that requires a wire is a method in which a single outlet or transmitter and a smart device or receiver to be charged are matched 1:1, and the IoT (Internet of Things) and smart device market It is impossible to implement a function that allows one transmitter to charge multiple receivers (IoT sensors or smart devices, etc.) at the same time in a non-contact manner required by
Radio Frequency (RF) wireless charging technology is an innovative technology that meets the needs of the market as an essential technology for the future metaverse and smart society.
Reflecting market changes and growth forecasts.
Select frequency-type wireless charging technology as the optimal technology for solving the problem at hand.
Promotion of commercialization.
Advantages of WARP Solution’s frequency (RF) method wireless charging technology
The charging efficiency of RF to DC, which converts frequency into DC power, which is a core function, is 60%, and it is possible to downsize more than 10 times compared to competitors.
The transmitter and receiver can transmit 20mW of power at a distance of 6 meters and can supply the same power to 12 receivers, enabling multiple simultaneous wireless charging using our MFMC (Multi Frequency Multi Charging) patented technology. Due to the characteristics of frequency-based power transmission technology, the received power increases or decreases according to the distance. When the distance between the transmitter and receiver is 1 meter, 2.24W of power can be received.

Securing IP through development know-how and securing charging solutions according to application environment (development of the world’s first multi-charging technology)
WARP Solution has developed the world’s first multi-wireless charging technology. As a result of continuous research and development, we have developed various charging solutions suitable for the application environment.
This can be classified into short-distance charging technology, mid-distance charging technology, long-distance charging technology, and implantable medical device charging technology. The short-distance charging technology applies the contactless wireless charging Qi method and the non-contact magnetic resonance wireless charging technology at a distance of less than 10 cm. The mid-range charging technology applies the non-contact radio frequency (RF) wireless charging technology to The area that can receive the frequency is wirelessly charged, and the remote charging technology has been developed to wirelessly charge the area that can receive the frequency within 6m by applying the non-contact frequency (RF) wireless charging technology. . The implantable medical device charging technology was developed to wirelessly charge medical devices (e.g. pacemakers, endoscopes, etc.) within a distance of 10 cm from the skin by using the penetration characteristics of non-contact frequency (RF) type wireless charging technology.
Based on these technologies, we developed Desk:on, the world’s first product with simultaneous magnetic induction/magnetic resonance/frequency charging methods.
This product can charge monitors, mobile phones, and various accessories at the same time with various charging methods. It is the only product so far that uses a single wire and is equipped with various types of wireless charging methods to charge, and it is energy box type charging. Since the box charges with frequency, multiple products can be charged freely at the same time, and the charging speed is fast, and the box cover must be closed to charge, so it does not affect the human body.
Competitiveness of WARP Solution compared to competitors
WARP Solution has all the major wireless charging technologies currently developed.
In particular, in the case of frequency (RF) technology, we have our own technology from element to finished product, and in the case of a receiver, it is possible to develop various products that meet customer needs while being 80% smaller than competitors with the same performance.
