Power over Ethernet adds efficiency, flexibility to wireless solar for SCADA: Carlson Wireless Technologies
Carlson Wireless Technologies used Power over Ethernet (PoE) to help increase system efficiency of solar-powered wireless products by up to 45%, eliminate inverters, and expand allowable cable length.
Carlson Wireless Technologies, provider of energy efficient wireless communications for rural and remote applications, integrated a new Power over Ethernet (PoE) device into its solar-powered wireless products, adding flexibility and efficiency. The new PoE unit increases system efficiency by up to 45%, allowing for greater solar system run times, the company says. Other benefits include reductions in required solar panel size and elimination of costly inverters. Carlson Wireless engineers also note that the new PoE allows a significant increase in powered cable length, expanding site configuration options for SCADA (supervisory control and data acquisition) applications.
Designed for remote locations, Carlson’s LongHaul (see photo) and Trailblazer microwave backhaul radios integrate with their solar power kits-directly monitoring radio and solar equipment via data throughput, temperature and voltage readings; sending e-mail alerts at customer-set thresholds to communicate problems before failure occurs.
"For over a decade we have been designing and manufacturing solar powered wireless voice and data links for very last mile," says Jim Carlson, CEO of Carlson Wireless. Adding the PoE design, he suggests, continues improvements in microwave communications systems. Other features include wireline quality, ultra-low latency, long distance TDM/IP voice and broadband data including POTS, 4-wire (E&M) to T1/E1s and Ethernet for telecoms, cellular backhaul, utilities (including Smart Grid) and public safety. Carlson offers North America frequency plans including unlicensed 900MHz, 2.4 GHz, 5.x GHz and licensed public safety 4.9 GHz frequencies as well as International frequency plans for 700 MHz and 3.5 GHz. www.carlsonwireless.com/products/LongHaul5x.php
