Contention Detection
Contention detection is essential for most anti-col-
lision algorithms. When two XRA00 devices have
the same clock rate and differ by only one bit, the
resulting difference in backscatter modulation
waveform should be readily detected by the Read-

communicating simultaneously. Differences in
backscatter modulation intensity can also be used
to help detect contention.
