1. the equipment (130) configuring network in the LAN wiring in building, this LAN wiring carries base band simultaneouslyBaseband signal in frequency band (41), this network carries numerical data based on wireless technology letter in digital data frequency band (43)Number, this equipment includes:

  • A LAN adapter (36) of described LAN wiring can be connected;

    High pass filter (32), this high pass filter (32) is coupled with a described LAN adapter, is used for transmitting numerical dataSignal in frequency band also refuses the signal in service signal frequency band (41,42);

    Antenna (22);

    Coupleding to the modem (17,37) based on wireless technology of described high pass filter, described modem is by structureMake and conduct the first digital data signal for being routed in digital data frequency band based on described LAN, with perform two-way based on pointThe digital data communications of group;

    The data connector (33) of data cell can be connected;

    WithThe transceiver (12) being coupling between described data connector and described modem, described transceiver is constructedFor carrying out packet-based numerical data two-way communication with described data cell;

    Up/down changer (31), this up/down changer (31) is coupled with described high pass filter (32), the RF signal of receptionBy this up/down changer (31) to downshift and by a LAN adapter (36) and high pass filter (32) feed-in LAN clothLine, and the signal based on wireless technology of LAN wiring carrying received and is upwards transformed to RF, and is subsequently fed to antenna(22);

    Described first digital data signal is OFDM modulation or the wireless signal of up/down frequency transformation, or described modulationDemodulator at least includes a part for radio modem (14,15).
