How much less does this cost, in terms of both time and money, compared to setting a password on your access point?

Oh, it costs more.

Brilliant!




Your conclusion is a result of a very poorly written title and lede. The greatest value of this product for your average consumer is not that it keeps your signal inside your home, but that it keeps other signals out.

Anyone living in areas of high population density can tell you how difficult it is to find an uncluttered slice of 2.4 GHz spectrum. It's next to impossible in places like Manhattan. I don't know just how effective this wallpaper is, but if it attenuates outside signals by even 50%, it would be a huge benefit.

EDIT: Another side benefit for businesses (even small ones) is control over what networks are available inside your office. Many businesses are in office complexes where WiFi signals overlap in to adjacent suites. I can't tell you how many times I've been to offices where users are connected to a neighbor's wide-open Wi-Fi network because they were ignorant of what network they should connect to.
