Recently, LS cable announced the completion of the research and development of magnetic resonance wireless transmission system, and exhibited the first verified model in South Korea.

Magnetic resonance wireless charging is the principle of inducing the receiving coil to generate a certain magnetic field and resonate with the transmitting coil. That is to say, similar to the sound emitted when two tuning forks resonate with each other, the meaning of power transmission after the two copper coils resonate in the same magnetic field by setting the wavelength. In this system, each of the transmitting and receiving sections contains a resonator that resonates in the transmission frequency, and only when the frequencies of the two resonators coincide can a high-efficiency transmission effect be achieved. Therefore, the LS cable shows that this technology requires a high level of technical capability to complete.

This method is more advanced than the electromagnetic sensing method currently widely used in IT machinery or electric toothbrushes and other products, and can achieve wireless power transmission within 2m. The LS cable used this technology to successfully start the TV and LED lights. In addition, the advent of this system has further promoted the research and development of microwave long-range wireless transmission technology.

LS cable predicts that with the popularity of portable IT products such as smart phones and the advent of various household appliances such as smart vacuum cleaners, the demand for wireless power transmission in public buildings and residential buildings will inevitably increase. Jin Hengyuan, director of the equipment business department, said, "The successful development of this system means that the business field of LS cable will open a new chapter. In the future, it will launch a main attack on the built-in market such as apartments and public buildings ".

As early as last year, LS cable has introduced the wireless charger for smart phones using electromagnetic sensing to the market, which has attracted wide attention. At present, it has completed the development of notebook computers, tablet computers and vehicle-mounted wireless chargers, and is preparing to enter overseas markets such as the United States and China. According to data provided by research company HIS, the wireless transmission market will show a huge growth trend of US $23.7 billion billion in 2015.

For the first time, LS cable has introduced a magnetic resonance wireless transmission system that can realize wireless transmission within a range of 2m. LS cable employees are demonstrating the process of using magnetic resonance wireless transmission systems to start TVs and smartphones.
