It’s not a full femto cell – it’s designed to only handle outgoing voice calls while handing off other functions to the 
carriers. I didn’t manage to synch my phone so can’t comment on the exact details but it did seem as if you do have to 
be aware of the relationships.

as I understand from the article it's basically a femto with some sw hacks to allow handset registration.

its legality, from a patent perspective might be uncertain. It would seem strange to me if they were able to obtain 
licenses to the gsm  patent pools.

from the frequency usage perspective, it varies significantly depending on countries.

the uk have licensed separate usages for low power devices for indoor use to companies other than the usual telcos.

in some countries low power devices are allowed within strict limits with no specific exclusion of gsm low bands

in other countries it is clearly prohibited

in others, it is unclear

the reason is that the regulations are somewhat layered. first came a liberalization of srd (short range devices) then 
the regulations for gsm;  at those times, with the cost of bts, noone really thought that bts would eventually 
economically become srd.

I looked into it in some european countries in the past, asking to various NRAs and obtained different answers.

ciao, s.

 [ Another issue -- how easily could such devices be subverted
   to intercept calls inappropriately?  Hmm.

The actual legality of this particular device is not immediately clear
to me without digging into some details.  I'm wondering if it has
received FCC approval?  I didn't find obviously relevant references in
the FCC database during an initial search.
