Today I found a very interesting research paper about
Power Consumption Analysis of Bluetooth Low Energy, ZigBee and ANT Sensor Nodes in a Cyclic Sleep Scenario. Not a surprise, BLE is the winner.
“We found that BLE achieved the lowest power
consumption, followed by ZigBee and ANT. The
parameters that dominated power consumption were not
the active or sleep currents but rather the time required to
reconnect after a sleep cycle and to what extent the RF
module slept between individual RF packets.”
