Sample Implementation of PLC in a Hotel

A hotel wants to be fitted with a multi-purpose computer network for the various

services it proposes to its customers and decides to install a PLC network.

Figure 11.12 illustrates the hotel network architecture with two buildings sup-

plied by a meter and two circuit breaker panels (one for each building).

Within these two buildings, the hotel manager wants the following services:

•

Building A:

•

Internet access with data confidentiality in each bedroom.

•

Internet access and connection of the restaurant cash registers to the hotel

information system.

•

Building B:

•

Meeting room 1, which proposes an Ethernet local area network over PLC

in order to allow exchanges between connected computers and a protected

Internet access.

•

Meeting room 2, which proposes the same services as meeting room 1 but

with compliance with the confidentiality of the data exchanged between

the networks of both rooms.

•

Two rooms with public Internet access open to the hotel customers.

•

Conference room with IP videoconferencing solution via the PLC network.

Network Implementation

Implementing this network requires the correct display of all the logical networks

connected to each other or not in the two buildings.
