PLC Networking of A Three Stars Hotel

Project Intro: 
　　It is a three star hotel and requires broadband internet access for its guestrooms locating on 3 -5 floors. 
　　There is a low voltage distribution room taking charge of  guestroom power supply on each floor of the hotel. 
　　The access point  for internet will be in distribution room on 5th floor. A router and a switch will also be placed here and we will connect PLC bridges (FPC-10MA, locating on each floor) to the switch with category 5 UTP cables. 
　　The hotel requires that internet access must be available in all guestrooms of the three floors.The hotel shouldn't be closed up for networking purpose, and no damage to the existing decorations and disturbance to the guests is allowed

Solution:
　　We placed 3 PLC bridges (FPC-10M) on 3rd, 4th and 5th floor respectively and connected them to the switch on 5th floor with vertical cables. Later we injected signal to the three phase power line with FPC-10M bridge, and the signal will cover the whole floor. 
　　 We finished networking construction without entering any guestroom and any interference to the hotel's business.
　　The hotel broadband usage-based billing system integrates broadband billing component, billing server and billing management system. The billing component is placed between router and switch, and it is parallel connected to a computer as the billing server, in which a billing server software is installed. An end user PC is selected to run billing management system to establishing,  cancel and limit usage-hour of user accounts.
