On the subject of reach yet complementary:
My best friend has this router and also lives in Hamburg on the 6th floor. If i put my car 150m down the road on the other side parks and exiting, my phone is already logged on. Just crass. However, I would recommend turn off the router to sleep unless you bleary-eyed in the same room ... you never know ... even if there is still no proven influences on the body, one should here but to play it safe.
