Abstract
A shared data communications system includes a network file server and two routers, each with its own address. A first router provides wireless access to a first part of the system. A second router provides wireless access to a second part of the same, shared system via the technique known as broadband-over-power line (BPL). In the second part, a first BPL unit is carried by the proximal end of an electrical conductor for receiving and sending signals between it and distal, second BPL unit on the same electrical conductor. The use of separate routers with different addresses and a power line to transmit and receive data to confine the wireless portion of the second part of the system to a smaller area increase the physical security of wireless communications with the second part, making it less likely data communications taking place in the second part will be accessed by others.
