Abstract
A LoRa transmitter and corresponding receiver where the detection sequence in the preamble is phase-modulated and includes an information that encodes the position in the preamble, such as a countdown index. Nodes that wake up to receive a scheduled download can determine from this information how far the end of the detection sequence is and manage their energy consumption accordingly. The phase modulation is compatible with legacy devices.
