Also be careful to look at certification costs. Even though the radios are=

operating in the free ISM band they must be certified and tested for=20
compliance.

I don't know about the Nordic products but I could not find any certificate=
 for=20
them.

If you look at the Microchip module MRF24J40MA, for example, it has a=20
regulatory approval for modular devices int the US, Canada and Europe which=
=20
means that you can use it and not have to do any further radio certificatio=
n=20
tests (you still have to do the standard regulatory tests for the end produ=
ct=20
though, just as usual).

You have to use a module with integrated driver and antenna to be able to u=
se a=20
precertified product.
