    • PROBLEM TO BE SOLVED: To provide a system having a LAN service unit (LANSU) backplane extender which provides an inexpensive way to increase a LANSU backplane bandwidth so that performance degradation that may otherwise be caused can be avoided. SOLUTION: A system having an increased LANSU bandwidth comprises: a backplane including a plurality of data traffic (DT) communication connections operable to communicate DT, a Line Unit including a WAN interface (I/F) and a DT communications (I/F) to the data traffic communication connections, a LANSU including a LAN (I/F), a DT (I/F) to a Bandwidth Extender, and DT communication (I/F) to the data traffic communication connections, and the Bandwidth Extender including DT communication (I/F) to the LANSU, and DT communication (I/F) to the data traffic communications connections, the Bandwidth Extender operable to communicate DT between the DT communications (I/F) to the LANSU and the DT communications (I/F) to the traffic communications connections.

    • PROBLEM TO BE SOLVED: To automatically revise a wireless LAN communication mode in matching with a wireless specification of each country.
      SOLUTION: A computer apparatus 10 has a current position data output unit 13 and an area data output unit 14 responsive to current position data from the current position data output unit 13 for outputting specific country data representative of a specific country including a current position. A wireless LAN connecting unit 12 is preliminarily given a plurality of wireless communication modes corresponding to a plurality of country data. Upon receipt of the specific country data, the wireless LAN connecting unit automatically sets, as a selected communication mode, one of the wireless LAN communication modes which corresponds to the specific country data and carries out transmission/reception via a wireless LAN 11 in the selected communication mode. Each of the wireless LAN communication modes is determined by a radio frequency channel and a transmit power level used in a country represented by the country data. The wireless LAN connecting unit 12 carries out transmission / reception by the radio frequency channel and the transmit power level deciding the selected communication mode.
