> Our team at Beep Networks is now working with LoRa radios here in San Francisco, and we’re getting signals through at over a mile of range. That’s in the city, through walls, with a tiny battery-powered sensor device — no towers or giant antennas involved. We know folks who are getting 10 miles in every direction when they put these radios on towers in rural areas, where there’s less interference.
