Re: Lowest power, short (10s of meters) range, low data rate, wireless technology

I'm looking for the lowest power (think: fewest battery changes)
wireless comms available:
- short range (ten-tens of meters)
- low data rate (KB/s) but the potential for CONTINUOUS data transfer
  (perhaps layering a protocol to ensure *reliable* transmission)
- need not be "standards" compliant (but must be licensed bands)
- tolerant of other "talkers" in their space

On paper, it appears that BLE would outperform ZigBee and ANT+

Anyone using any of these in a *battery* powered application
to comment on their actual obsebrvations?

I have some bluetooth audio link modules
can be used for data too, tx and rx both battery based, very small.
Runs about a up to few hours on a battery charge
