The problem of LoRa is that is just slotted ALOHA, which maximum data throughput is only 36.8% of the available bandwidth. The more you transmit the more packets collide and data must be retransmitted in a spyral of death, so the system needs to operate using a small portion of the bandwidth not to collapse. Practically if everyone in New York would use LoRa and have dozen of devices in their homes using those bands, the bands would be jammed and nothing would work.
- awelkie 7y agoLoRa is just a PHY, LoRaWAN is the MAC. And last I checked LoRaWAN used ALOHA, not slotted-ALOHA, which is even worse. But I knew a few years ago they were talking about adding beacons to the MAC to enable slotted-ALOHA, so maybe my knowledge is out-of-date?
