Hello Dieter,

 

In addition to the responses you already received (which I like), I would
ask you to check that your host ITE product is really 'ancillary equipment',
as defined in EN 301 489-1.

 

I think that as others have pointed out, your host product will most likely
continue to need to meet EN 55022 Class A, whilst you should check that the
emissions from your WiFi operation meets the emissions limits of EN 300 328
(and/or EN 301 893).

 

 

Thanks,   Michael.

Subject: [PSES] Radio in class A product

 

Dear members, 

 

I am adding a radio (WiFi module)  to an ITE class A product. The product is
tested under CISPR 22/24. I was told now that, because of the radio, the
standard to apply is EN 301489-1, and therefore my product has to meet the
class B of EN 55022 for emissions. 

 

My opinion is that product and radio have to be tested separately and test
the product to EN 55022/24 (without radio, or with the 2.4 GHz transmission
frequency filtered), and the radio or radio module by itself under EN
31489-1. Is that correct? Where can I find the right interpretation? 

 

 

 

Sincerely, 

 

Dieter Paasche
