The two-fold demonstration, done in collaboration with UCA/CNRS at its LEAT laboratory, demonstrates
1) Unrivaled IoT network capacity
Ternwaves demonstrated that its modulation technology is able to accommodate 40 simultaneous IoT receptions @ 730 bps in a single 250kHz channel at 868MHz. Incoming signals were generated by 4 different asynchronous transmitters with 100% duty cycle and were realized without any external synchronization mean.
This unique collisions robustness constitutes a major breakthrough in the IoT domain, unlocking the long known critical bottleneck of LPWAN network capacity.
2) Record-breaking RF sensitivity
In the same session, Ternwaves demonstrated extreme RF sensitivity enabling ultra-long range low power transmissions and very low power consumption.
Sensitivity : -143.5dBm @ 210 bps
Measurement conditions : 1% PER, 20bytes payload, 250 kHz BW, data rate 210 bps.
Performance was achieved with fully independent packet per-packet processing (no latency) and without any external synchronization mean (asynchronous timing and free-running clocks and frequencies on each side).
This record-breaking RF sensitivity coupled to the associated major system capacity boost clearly opens a new era in the IoT market and paves the way to the long-awaited massive IoT market.
