Push to Talk: LoRaWAN for Social Isolation Relief
summary
A LoRaWAN push‑to‑talk button links offline households into a call‑back service so users without broadband ring and talk to others with no apps or setup required, deployed in Liverpool using TTN gateways and LoRaWAN buttons with 5G backhaul. A trial shows it works in homes lacking internet, averages 15‑minute calls with a longest 1 hour 42 minutes, and addresses a digital gap where 50% of older households without broadband could otherwise be isolated.
