A radio communication network includes at least one mobile transceiver unit in communication with at least one base transceiver unit that facilitates communicate with at least one host computer for storage and manipulation of data collected by bar code scanners or other data collectors associated with the mobile transceiver units. The radio network implemented by the mobile transceivers and base transceivers adapts to compensate for the wide range of operating conditions by adjusting its operating parameters. Such operating parameters include: the length and frequency of spreading codes employed in direct-sequence spread spectrum communications; hop frame lengths, coding and interleaving in frequency-hopping spread spectrum communications; the method of source encoding used; and the data packet size in a data segmentation communication scheme. The base transceiver is responsive to information contained within transmissions received from the mobile transceiver units in establishing data packet sizes as well as to the transmissions themselves. The base transceiver is also responsive to the quality of transmissions received from the mobile transceiver units in determining whether to modify current data packet sizes.
