Verification of antenna/distance

Hello.

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.

Dear ,

until now NFC Forum as not yet define a T5T  reference listener (Tag reference 15693)  ,  that could be used tpo evaluate NFC poller when using Type V Technologie (ISO/IEC 15693) , but ISO as done it  (ISO/IEC 10373-7  Reference VICC)  and you can probably find a supplier on internet to order one .

6.3 Reference VICC

Reference VICC’s are defined to test

—

H

min

and

H

max

produced by a VCD (under conditions of loading by a VICC)

— the ability of a VCD to power a VICC

— to detect the minimum load modulation signal from the VICC.
