Creating a monitoring system for utilities can be a big challenge, particularly since it is often necessary to install the latest remote management equipment at both mobile and fixed locations. One of the main difficulties is that the wiring for such a system can be both difficult and expensive.
One of the ways around this problem is to use a cellular solution. Moxa's own industrial-grade IP modems have dual power inputs, and a relay that can be used to send alerts if one of the power sources fails. The IP modems allow you to create a secure TCP/IP connection to essentially all of your remote sites and devices. Since customers only pay for the data they actually send over a cellular connection, this type of solution can be even less expensive than the more traditional landlines.
IP modems use high speed, wireless GSM/GPRS/EDGE technologies, giving utilities the ability to create a Wireless WAN (WWAN) connection to remote sites for real-time 2-way communication with RTUs, meters, FTUs, and other equipment. GSM/GPRS/EDGE provides excellent coverage in both metropolitan and rural areas, making this technology even more beneficial to utilities that have assets scattered over a wide area.
The “always-on” technology of high speed IP modems is ideal for utilities, and since customers only pay when data is transmitted, monthly operating costs can be kept at a minimum.
Security IP modems provide a high level of advanced data encryption and authentication technologies to make the TCP/IP connections secure. Customer do not need to modify existing software applications, and consequently can set up their connections easily.
