ABB than for electricity, in that the value proposition of add-on applications (like GE Cisco Cooper Industries Itron Current Group Eaton Landis+Gyr* RuggedCom* GE Sensus Silver Spring Networks Schneider Electric Echelon SmartSynch* Siemens demand response) is low and the meter circuits must operate from batteries since they do not have access to electricity. This further complicates the product strategy of a major meter supplier. Communications More Attractive to Majors No single technology solution exists for meter communications. The layout of electric distribution networks generally favors wireless communications in North America and power-line carrier communications in EMEA. Optimal communications technology also depends on the geographic density of meters. A utility may have widely different densities within its service area, often consisting of urban, suburban, and rural regions. Older AMR meters have limited one-way communications and were designed to communicate only with readers supplied by the same manufacturer. Suppliers used this technology as a differentiator and as a means of customer lockup. Limited communications capability (combined with the extremely long life expectancy of meters and their high cost of installation)
