RF Shielding Issuem- where they are connected to ?

RF Shield Issue

Hi All,
Does GSM modules require RF shields for the circuits that they are connected to ? Can you provide some further knowledge please ?

Thanks in advance

Re: RF Shield Issue

The GSM module doesn't radiate itself, the antenna does. So shielding of electronic circuits that are possibly susceptible to
interferences is mainly a question of the antenna position. Standard logic and processor circuits residing on a a ground plane
shouldn't have problems with a near by antenna. For sensitive analog circuits, depends on. Another question is active EMC of the
circuit, a bad designed digital circuit can possibly disturb the GSM receiver.

FvM, does that mean if we place antenna considerably far away from electronic circuit we will not need a shield at all (assuming there are little to no EMC issues)?

There is also the issue of the other electronics radiating energy in the GSM band and hampering the reception.
