Comparing Average Battery Life of DASH7, WiFi, and Bluetooth

Short battery life requires costly recharging or battery replacements, rendering most wireless technologies unusable for “Internet of Things” applications

DASH7

DASH7 draws a very small amount of power from a battery – less than 1 milliwatt – and can even operate using a solar cell and other clean, energy harvesting technologies. DASH7 has the longest battery life of any wireless data standard in the world.

WiFi

Mobile WiFi devices like a smartphone are typically unable to provide battery life of more than a few days, often much less.

Bluetooth

The Bluetooth radio and devices like smartphones draws a substantial amount of power, and even the larger battery on a phone will be drained by Bluetooth in no more than 1-2 weeks. A new form of Bluetooth called Bluetooth Smart enables multi-year-battery life for some medical and sports devices (not phones) when operating in “one way” mode, though use of this version is still in its infancy.
