Abstract: In one embodiment, a method includes: obtaining a multi-protocol schedule, wherein the multi-protocol schedule includes scheduling information characterizing packets associated with a plurality of wireless protocols, wherein each of the plurality of wireless protocols is associated with a respective virtual gateway of a plurality of virtual gateways; detecting, by a wireless transceiver, a first packet related to a first wireless protocol of the plurality of wireless protocols based on the multi-protocol schedule; and transmitting, by the wireless transceiver, the first packet related to the first wireless protocol to a first virtual gateway of the plurality of virtual gateways. According to some embodiments, the method is performed by a device (e.g., a MAC preprocessor) that includes a wireless transceiver, one or more processors, and non-transitory memory.

Abstract: In one embodiment, a device in a low-power and lossy network (LLN) makes, based on a temperature measurement, a first adjustment to a frequency for a wireless channel used by the device to communicate with one or more neighboring devices in the LLN. The device receives, via the wireless channel, a packet from one of the neighboring devices that indicates a transmit frequency for the packet. The device calculates a frequency offset based on a difference between the transmit frequency for the packet and the adjusted frequency for the wireless channel. The device makes, based on the calculated frequency offset, a second adjustment to the frequency for the wireless channel used by the device to communicate with the one or more neighboring devices in the LLN.
