I'm still researching which one to use in Paraguay, but it seems that it's going to be 915MHz as the Americas are in ITU region 2: http://en.wikipedia.o...­ and http://en.wikipedia.o...­
However, reading some other sources, there are countries like Brazil where it seems that 433 and 915 could be used: https://code.google.c...­
