14.4 BeaconTimingReq

1. This command is sent by the end-device to request the next beacon timing and channel.
2. This MAC command has no payload. The BeaconTimingReq & BeaconTimingAns
3. mechanism is only meant to accelerate the initial beacon search to lower the end-device
4. energy requirement.
5. The network may answer only a limited number of requests per a given time period. An end-

22 device must not expect that BeaconTimingReq is answered immediately with a

1. BeaconTimingAns. Class A end-devices wanting to switch to Class B should not transmit
2. more than one BeaconTimingReq per hour.
3. End-devices requiring a fast beacon lock must implement an autonomous beacon finding
4. algorithm.
