Project Intro

Broadband Internet access is already being enjoyed in densely populated areas and developed regions, but since some rural and less developed areas still do not have broadband service, some companies have investigated how to provide reliable and cost effective broadband service to these areas. One of the key issues was determining the best technology to use for the last mile of the connection. Since the deployment and use of wired systems in remote areas is usually not feasible due to the high cost, wireless is the best candidate. In this application we describe a pilot project that uses power lines to provide wireless broadband service. The solution combines the power distribution grid with Wi-Fi technology to create reliable, high-capacity, and cost effective network access. The main advantage of BPL (Broadband Power Line) technology is that the last mile of access is achieved using the power grid, eliminating the need to create an additional infrastructure.
 

System Requirements

• All I/O status can be controlled with the SNMP protocol
• Event response control is based on Ethernet communication status
• Support for periodic control
• Download configuration and firmware remotely 

 

Moxa Solution

Providing broadband access to end users through the electric power grid is achieved through a Wi-Fi network. With Wi-Fi technology, LV (low voltage) power lines are not needed. Data packets travel along the power line in the 1 to 34 MHz frequency range together with the electric current, which is transmitted at 50 or 60 Hz. Users can then use Wi-Fi to connect to the BPL communication grid. The BPL network has been installed on two MV (Medium Voltage) lines with a total length of 70 km. The network includes 110 BPL units that are used for monitoring. In addition, Moxa's ioLogik E2210 has been installed in each BPL unit. The system diagram illustrates how the Moxa ioLogik monitors the status of Wi-Fi communication. When communication is lost, the Wi-Fi access point is restarted automatically by the ioLogik. The ioLogik sends out a pulse output to trigger the indicator light on the tower, making it possible to monitor all I/O signals from a central site with SNMP. In addition, users can control the irrigation pumps remotely with SNMP protocol.

 

 

Why Moxa?

Moxa offers an IT-friendly intelligent I/O that combines both IT and IA features, giving IT engineers access to functions not commonly used in the IT world. To save costs, Moxa's ioLogik can be used in the same manner as a small RTU for these kinds of applications, including telecom, power, and transportation.
