How do I know that my design is good enough for all kinds of phones?
We have the PCB inside a cabinet, where the phones can max be as close as 3-4cm to the antenna, (a PCB-antenna and a M24LR).
How do we verify that we fulfill some kind of standard (in the receiving form). If we test with 1 or 2 phones, how do we know that all other phones on the marked (and future phones) will be able to work as well?
Do it exist some kind of reference “device” (that we can buy), that guarantee that if it works with this, then it will work with all phones. All phones MUST be stronger then this reference to fulfill the standard…. Something like this. J
