Calibration Box (CalBox)

...

• Before being synchronized, each OpenMote only listens on channel 11 and wait for CalBeacon sent by MM1.

• After being synchronized, each OpenMote only sends multiple CalBeacon frames on specific slot at specific channel. E.g.

  • MM1 can only send frames beacons on slot 0 on channel 11. During all other slots except slot 0, MM1 listens on channel 11,

  • MM2 can only send frames beacons on slot 1 on channel 12. During all other slots except slot 0, MM2 listens on channel 12,

  • MM3 can only send frames beacons on slot 2 on channel 13. During all other slots except slot 0, MM3 listens on channel 13,

  • … …

• After synchronized, when an OpenMote received a frame from SCuM, it sends back an Acknowledgement (CalAck) on the same channel it was listening before.

  • The Acknowledgement contains the frequency_offset of the incoming frame.

Initialization

SCuM is placed in the communication range of CalBox

...

The SeqNum is reset to 0 at beginning of each slot, it increments at each sub-slot when a frame is sent out.
