- 6. Weightless-P vs. LoRaWAN SynchronousNetwork Weightless-P’s organised, synchronous networking means every device and base station knows exactly when to talk and when to listen. This is identical to our reliable cellular networks that our cell phones depend on. Without it, high collision rates will occur. LoRaWAN is NOT a synchronous network protocol. It uses a simple communication scheme called ALOHA in which devices send immediately and if unsuccessful, send again. This scheme is power consuming and unreliable.

- 7. Weightless-P vs. LoRaWAN Paging/ScheduledRadio Weightless-P supports both network originated and device originated traffic with paging capacity. Multiple paging sub-channels with low latency in both uplink and downlink reduces reception time and also reducing battery drain. LoRaWAN end devices are unreachable until the device wakes up for uplink transmission. When thousands of devices are sending data, a Weightless-P base station will be able to tell each device the exact timing and channel to utilize in order to avoid collisions and ensure the successful delivery of your important data.

Weightless-P also supports over-the-air file transfers that can be used to transfer application software, scripts, setting, encryption keys, databases, or module firmware updates. There has been no proven, reliable method for LoRaWAN to support FOTA (firmware-over- the-air) as downlink is very limited.
