That's been a month of hard work, and we have achieved significant results. The most interesting is the development of more narrow-band modulations/waveforms with a bandwidth of 500/250/125 kHz. We are heading towards the use of the ISM 868 MHz band. In this range, it is possible to radiate 0.5W of power for unlicensed IoT/M2M services. More information in the next month.
We also made new cooperation with the Institute of Aerospace Technologies (IAT) NTUU "KPI" and the section of Aircraft and Robotic Complexes of the Junior Academy of Sciences of Ukraine. The relay node for high-speed relay transmission, which combines 2 modems, was finalized. We are working on arranging a test line.
