Due to convenience, all communication devices are changed to wireless from wired and there are various wireless functions that enable multi-connection between several devices from one wireless device. Each country sets the requirements depending on special features on wireless functions for smooth communication.

RF test
The indiscriminate use of radio makes it impossible to deliver accurate information due to interference. Each country regulates and manages the use of frequency, intensity, bandwidth and spurious, and selling is not allowed if it doesn’t meet the limits required by the state in the country.
Also, it is required to check whether it meets the requirements for each country because frequency allocation is different in each country.

SAR test
SAR (Specific Absorption Rate) is the amount of energy absorbed into the body from the electromagnetic waves generated from electronic devices, and it is applied to wireless devices which conduct wireless communication by generating electromagnetic waves. It is controlled and regulated because it may have a negative impact on the human body due to thermal action and stimulating effect of these signals. We divide it into head part, body part and wrist / ankle part depending on conditions of use of the radio product. We implement shared SAR tests on the parts so that all users can identify the amount of energy absorbed into the body.
