Why wireless product certification

Theory:

The radio frequency is infinite. Hz)

In practice:

The frequency of general civilian products is concentrated in (0 ~ 40GHz)

So how to manage the limited frequency that is commonly used?

This requires the division of our frequency into various areas of use, range, emission size, etc.

And countries in the national security considerations, in the 0 ~ 40GHz many frequencies are not open to civilian products, we must avoid using or inadvertently occupying these frequencies, resulting in a variety of unnecessary consequences.

Various considerations require us to conduct various tests on wireless products and obtain certifications in the appropriate countries. --- < a href = "http://www.globalgd.com/" > < strong > ETL certification < / strong > < / a > agencies < / span > < / p >
