Check if the packet fragmentation is possible for transport connection.

Parameters

connection	the downlink connection
availableSymbols	maximum number of OFDM symbols to be used by the burst
modulationType	the modulation type to be used for the burst

Returns: false if packet fragmentation is not possible, true otherwise
