This Digital Radio Gets Messages to the World’s Remotest Locations

Automated excerpt

Wherever they go, they use HERMES to help connect locals to the rest of the world. Bloom spoke with IEEE Spectrum about how HERMES brings better data rates and encryption to shortwave radios. How does HERMES connect remote locations? Peter Bloom: We use the ionosphere as our satellite—or mirror—which helps us move information, voice, and data over really long distances. What can HERMES send that a basic voice radio can’t? Bloom: HERMES is a software stack—it’s a set of different programs that all work together in order to be able to send data over HF.
