[4eyes] SIGCOMM best paper award - Battery Free Wireless devices

[Saiph Savage]

wow, very cool! I have had some brief contact with the people involved in
the SIGCOMM paper. It is important to note that there do seem to be still many
issues, e.g.,  their approach seems to only work over extremely short
distances. So if ambient backscatter is going to be implemented over a
larger area, the multipath or modulation of the carrier may be problematic.
Also typically ambient RF power levels vary drastically with distance from
TV transmitters. There is also the issue of potential interference from
such mode of communication on TVs etc.
Still very interesting research, and I think it's  a good exercise to think
about the user experience possibilities when such technology does become
 available.
cheers,
