Leaky Coaxial Cable Wireless WIFI Internet Access

clever. This is exploiting a natural property of all wire: it 'leaks'. For example, if you get a powered speaker, and attach a very long, badly insulated speaker cable into it, it will probably recieve the radio/ passing taxi communications. Or if you run many cables with different uses through the same trunk, you might get cross-over interference. For sure, a pain in the backside in the theatre... but has one common use:Induction Loops for Hearing Aid devices. people with a hearing aid need to hear the church sermon or the lecture so they turn their hearing ait to 'T' and it will tune into the loop frequency. These work by running a 'loop' of copper cable around the room. because the cable 'leaks' signal, it functions like a small scale local broadcast antenna. higher quality loops use coax cable. this is a clever utilisation of a normally annoying feature of cables.
