Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
There is nothing wrong with using wireless for signalling (plane and shuttles must use wireless!)  The problem is in designing for failure modes.  The same applies to signalling - as DoDo mentioned, cable thieves are a problem just as devastating to signal strength as a failed transmitter.  Indeed, with sensible hardening wireless is probably safer.
