Comments
The TX preamble should be made long enough to allow the receiver to
acquire the signal
The energy dwell timer should be set long enough to allow the receiver to
detect the energy²
The ID dwell timer should be set long enough to allow the receiver to detect
the chip ID or global ID²
The length of packet will turn the receiver off after the number of data bits is
received
Notes:
1. The need for a preamble and the type of preamble is determined by the data modulation selected.
2. The dwell timers need to be long enough to allow the receiver to stay active from the time it turns on due to energy and the time that the desired event occurs. However,
making this number the maximum may in the case of false energy detection or signal corruption may waste system power unnecessarily.
