What is QOTA
QOTA is a wireless communication protocol developed by Qoto Smart, which is also optimized in depth for the IoT scenarios. QOTA uses the same frequency bands to LoRa system, but it owns some advantages over LoRa and resolves many pain points in wireless communication.
Why QOTA
Advantages Over LoRa and 4G
QOTA VS 4G
QOTA solves the problem of 4G in unstable signal in remote areas;
QOTA has not the potential issue of insufficient bandwidth of 4G base stantion in future;
QOTA VS LoRa
QOTA does not need provision gateway and sub-device like LoRa;
QOTA does not need the troublesome reconnection if gateway gets off-line;
QOTA has better interference suppression;
