| 摘要 |
The present invention includes installing a computer network ( 51 ) in a building ( 24 ) by coupling together a hub ( 50, 350 ) and a number of network adapters ( 100, 400 ) together with previously installed cabling. Data signals are transmitted from the adapters ( 100, 400 ) to the hub ( 50, 350 ) within a first frequency range and converted to frequency-converted data signals within a second frequency range for transmission back to the adapters ( 100, 400 ). The network ( 51 ) interfaces to an ethernet bus ( 37 ) through each of the adapters ( 100, 400 ).
