1. A device, comprising:
multiple transceivers configured to:
receive a message from an external node, wherein the message is received by each of a plurality of transceivers; and
transmit by each of the plurality of transceivers a respective data frame to the external node in response to the message, wherein each transceiver initiates the transmission of its respective data frame a predetermined time period after receipt of the message by the transceiver and the transmissions of the data frames from the plurality of transceivers overlap;
a non-transitory computer readable medium that stores computer executable instructions;
at least one processor, wherein when executing the computer executable instructions, the at least one processor is configured to:
generate, for each of the plurality of transceivers, the respective data frame, wherein:
each of the data frames comprises a first training sequence and a second training sequence; and
for each of the respective data frame:
the first training sequence is located at a start of the respective data frame and is arranged to start a first time period after reception of the message by the respective transceiver, wherein the first time period differs from the first time period of each of the other data frames; and
the second training sequence comprises a cryptographically generated training sequence and is arranged to start a second time period after reception of the message by the respective transceiver, wherein the second time period is the same for each of the data frames.
