The National Radio Research Agency (RRA) announced on December 23 that it will revise the standards for equipment that use radio waves on December 24. 

The RRA said that the revision lays the groundwork for the commercialization of magnetic resonance-based wireless charging equipment. When using the magnetic resonance method, charging is done by adjusting the radio frequency between a device and a wireless charger. In contrast, the magnetic inductive charging method requires a device to be put on top of a charging pad. 

Recently, Korean mobile phone manufacturers have completed the development of products using the magnetic resonance method, and thus magnetic resonance-based wireless chargers are likely to become mainstream in the first half of next year. 

Wireless power transmission technology refers to the method to transfer electricity from a charger to a device using the inductive principles of magnetic fields, without the need of a charging board. 

Meanwhile, the revision includes a guideline for the frequency that wireless power transmission equipment uses and the voltage levels per method.
