    System must introduce only one packet at a time to the network for transmission. The PK parameter determines the maximum number of bytes. Each hop (H) decreases network throughput by a factor of 1/(H+1). Additional repeaters add network redundancy without decreasing throughput.

    Polling Remote responds by sending the data from its DIN buffer following the RB and RO parameters. When there is no eligible data to send, the Polling Remote does not respond. The Polling Base polls the next address in the polling sequence after a short delay. XBee®/XBee-PRO XTend Compatible (XTC) RF Module User Guide...

    During back-off delays, the TX device goes into Idle Mode and may receive RF data. This can have the effect of increasing the back-off delay, as the device cannot return to Transmit (or retransmit) mode as long as it is receiving RF data.
