Is above 1GHz the new Wild West?
This post is by Steve Hayes, EMC & Safety Managing Director at TRaC.
Is the spectrum above 1GHz open for anyone, just like the old Wild West?
EN55022:2006 introduces radiated emission requirements above 1GHz for the 1st time, but the delay in withdrawing the old 1998 version, means that there are no test requirements above 1GHz.
Does this really mean that the spectrum has no protection or are frequencies above 1GHz less of a problem?
In reality, things become much more directional as the frequency increases, reducing the probability of interference with other systems, so hopefully we won’t see any real-life problems due to the delay in moving on from the old standard.
