When a packet to be transmitted from the Radio interface is longer than the MTU (Maximum
Transmission Unit) set, the RipEX router performs standard IP fragmentation. A packet longer than
the configured size is split into the needed number of fragments, which are then independently
transmitted - the first packet(s) is (are) transmitted fragment-size long, the last packet contains the
remaining bytes. The reassembly of the fragments into the original packet normally takes place in
the unit at the end of the path.
Reducing the maximum length of a frame on a Radio link may improve its performance under unfa-
vourable conditions (interference, multi-path propagation effects). However the recommended place
to determine the packet size is the actual user interface, e.g. a COM port. Note that the IP fragmenting
is possible in the Router mode only.
