PulzeLab C1 is the NGI0 Commons grant tracked as LoraMessaging: a portable, standalone handheld for LoRa mesh messaging. LoRa uses open UHF ISM bands to carry small packets over long distances through a mesh — no cellular operator, no always-on internet.
The project aims at an affordable, durable device that is still usable without a radio-hobbyist background: simple hardware, user-facing software, and a housing that can be 3D-printed in small runs or manufactured at volume. That is a different failure mode from internet messengers: when the mobile network or a chat vendor is down, the mesh can still move text.
