Elster has introduced a new version of its REXUniversal meter designed to enhance the product line’s interoperability and interchangeability with other smart grid vendors. According to Elster, “This version incorporates point-to-point cellular communications technology which greatly expands the number of rural and remote residential utility customers who can be served by smart meters and modern smart grid systems.”
By adding cellular support, the REXUniversal meter can now operate on both cellular and mesh advanced metering infrastructure (AMI) networks. Verizon (CDMA) and AT&T (GSM) cellular networks are supported with this release. Elster also plans to expand support for third-party communications technologies.
Elster Solutions president Mark Fronmuller adds: “There are multiple benefits of the REXUniversal meter. It is a big step toward our goal of giving our customers new opportunities to save time and money via networks that interoperate as a single, integrated AMI. Our vision is a world where utilities have the ultimate in flexibility, security, and cost savings through the ability to switch between mesh, cellular and multiple head ends as their needs, budgets and smart grid plans evolve.”
Atmel Corporation has also introduced a new solution: a power line communication system-on-chip (SoC) solution designed for smart metering applications.
Atmel reports the SAM4CP16B “is an extension of Atmel’s SAM4Cx smart energy platform built on a dual-core 32-bit ARM Cortex-M4 architecture..”
Andres Munoz, Atmel’s marketing manager of smart energy communications, says, “We continue to build on the success of our industry leading SAM4Cx platform and offer best-in-class embedded connectivity, flexibility and cost structure for high-volume smart metering deployments. Furthermore, additional enhancements developed to meet PRIME standard specifications provide unprecedented performance in rigorous environments.”
The solution features integrated low-power driver, advanced cryptography, 1Mbytes of embedded Flash, 152Kbytes of SRAM, low-power RTC, and LCD controller.
