Unlocking the Spectrum: LPWAN Frequencies Demystified

When it comes to the frequency bands used for various technologies, these depend on your location globally. There are technologies based on mobile networks, such as LTE-M and NB-IoT, as well as technologies relying on unlicensed frequencies like SigFox and LoRaWAN. Additionally, there are short-range technologies like Bluetooth LE, among others. The technologies employ different types of signaling and operate in various frequency bands, as detailed in the table below. LPWA networks transmit a limited amount of data, often just a few bytes per message, and operate within relatively restricted channel spaces.

Frequencies Table for LPWAN in Europe

Technology Bandwidth Duplex Number of Antennas Frequency (MHz) Latency
LTE-M 1.08 MHz Full/half 1 699-960/1710-2170 10-15 ms
NB-IoT 180 kHz Half 1 699-960/1710-2170 <10 s
SigFox 0.1-100 Hz Half 1 868.130-869.525 >20 s
LoRaWAN 125 kHz Half 1 433/863-870 1-100 ms
Bluetooth LE 2 MHz Full/half 1 2,400 <3 ms

Note: LPWA stands for Low Power Wide Area, and frequency bands vary depending on geographical location. Latency times are approximate and may vary depending on network load and other factors.
