A Study on the Technical Regulation of Weak Electric Filed Strength Radio Equipment about 58kHz Frequency Band

Abstract

This paper compared the output limits value of the Korean weak electric field strength wireless device in the 58kHz band with the standard values of foreign countries. Through this, the study confirmed that the Korean regulation was lower by about 50dB than those of the USA or Europe. In order to prove this, the study measured outputs by entrusting the 58kHz EAS system to two measuring companies. As a result of these measurements, electric field strengths were shown to be 112dB㎶/m and 108dB㎶/m respectively, and these values were confirmed to exceed the current Korean standard of 102.7dB㎶/m. Accordingly, it is deemed necessary to review the specifications of the Korean standard in the 58kHz band.
