The Femtocells World Summit is in London this week; I haven’t attended, but I have seen articles about it that have me wondering whether there are interesting security issues emerging.
First, what’s a femtocell? Essentially, it’s a short-range, miniaturised version of a mobile phone mast. However, instead of being directly plumbed in to the phone network, calls made through a femtocell are routed over broadband Internet connections so they can be used in areas where the normal phone network coverage is poor or non-existent.
