[cma-l] Singing posters and talking shirts stealing from your FM signal...

[Ian Hickling]

".......we developed a new way of communication where we send information by reflecting ambient FM radio signals that are already in the air, which consumes close to zero power.” The UW team has — for the first time — demonstrated how to apply a technique called “backscattering” to outdoor FM radio signals. The new system transmits messages by reflecting and encoding audio and data in these signals that are ubiquitous in urban environments, without affecting the original radio transmissions......"
Oh yeah?

This is a fascinating bit of work – though it must raise a whole raft of regulatory and legal issues:
