A lot of IoT applications required a high level of autonomy and battery lifetime. An absence of power supply or low maintenance cost requirements pose the demand on long-lasting batteries and optimized power consumption.
20 years of autonomous service
Wired systems are expensive and difficult to maintain. The WAVIoT radio modules achieve long-range network connectivity through short 1 000 ms bursts of data that draw only around 50 mA.
The rest of the time, the system draws only a few μA.
The result? These batteries about the size of AA can last for years, keeping costs and maintenance low. If you were to run a similar process through cellular modems, the batteries would only last a few days like your smartphone.
