Channel Activity Detection

The use of a spread spectrum modulation technique presents challenges in determining whether the channel is already in

use by a signal that may be below the noise floor of the receiver. The use of the RSSI in this situation would clearly be

impracticable. To this end the channel activity detector is used to detect the presence of other LoRaTM signals. Figure 10

shows the channel activity detection (CAD) process:
