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 bandsin other countries it is clearly prohibited in others, it is unclearthe 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.

I'm wondering if it hasreceived FCC approval? I didn't find obviously relevant references inthe FCC database during an initial search. --Lauren-- NNSquad Moderator
