Power Consumption Basics: LoRaWAN vs. Wi-Fi
How LoRaWAN Saves Power
LoRaWAN stands out for its energy-efficient design, making it a go-to for industrial IoT devices that need to last years without frequent maintenance. Its secret? Devices only transmit data when necessary and otherwise stay in sleep mode. This "duty cycling" approach ensures minimal energy use compared to other technologies that don’t optimize their sleep cycles.
LoRaWAN devices operate by waking up at scheduled intervals to collect and send data, significantly cutting down on power consumption. With low data rates ranging from 250 bps to 22 kbps, they remain energy-efficient while maintaining reliable communication – especially in rural areas. Another advantage is the adjustable transmission power. For instance, devices typically draw about 50 mA at 5 dBm, increasing to just over 120 mA at 19 dBm. This adaptability helps extend battery life across various deployments.
Wi-Fi’s High-Power Requirements
Wi-Fi, on the other hand, is designed for high-speed data and constant connectivity, which naturally demands more energy. Unlike LoRaWAN, Wi-Fi devices stay connected continuously, resulting in a steady power drain.
With speeds reaching up to 9.6 Gbps (Wi-Fi 6) or 15 Mbps (Wi-Fi HaLow), Wi-Fi delivers impressive performance but at a cost: higher energy consumption. This makes Wi-Fi better suited for applications with access to an uninterrupted power supply.
Power Usage Numbers Compared
When comparing power consumption, real-world tests highlight the stark differences between these technologies. For example, experiments using Heltec WiFi LoRa 32 nodes revealed the following:
- Wi-Fi devices achieved a battery life of 10 hours and 10 minutes at a 5-second transmission interval. Extending the interval to 30 seconds slightly improved battery life to 11 hours and 14 minutes – a gain of just over an hour.
- LoRaWAN devices, on the other hand, maintained a consistent ~10-hour runtime at both 5- and 30-second intervals with default settings. When transmission power was optimized to 10 dBm, LoRaWAN outperformed Wi-Fi, adding roughly 20 more minutes of battery life at the 30-second interval.
One key takeaway is LoRaWAN’s ability to maintain stable power consumption regardless of transmission frequency. During sleep mode, LoRaWAN devices operate in microamp ranges, spiking briefly to 50–120 mA during transmissions. In contrast, Wi-Fi devices maintain a higher baseline power usage due to their always-on nature.
These differences have practical implications for industrial use. LoRaWAN sensors can often run for years on a single battery, while Wi-Fi devices typically require continuous power or frequent battery replacements – sometimes every few months, depending on the data load and transmission frequency. For U.S. industries, this data underscores the importance of choosing the right technology for long-term efficiency and reduced maintenance.
