Configuring the Radio Network 4 - 15

Setting Fragment Size (Fragment)

This parameter determines the largest packet size that may be transmit-

ted. Packets that are larger than this size will be broken into pieces that

are transmitted separately and rebuilt on the receiving side.

If there is a lot of radio interference or collisions with other nodes, the

smaller lost packets can be retried faster and with less impact on the air-

waves. The disadvantage is if there is limited interference, long packets

will take more time to transmit due to the extra packet overhead and

acknowledgments for the fragments.

Set the fragment size between 256 and 2048 bytes.
