Assuming you mean mesh in general: Meshtastic like projects - emergency communication - low power data transfer for sensors - low data rate data transfer for mobile groups. Air softers use it to transmit information to each other while playing. HaLow: - "high" data rate over shorter range, though much higher range than 2.4 wifi - data sharing between mobile groups like above, but high enough bandwidth for low quality video - large area wifi deployments
