China investment in smart grid tech
Chinese smart meter manufacturer Waison has seen turnover from advanced metering infrastructure increase by 17% since 2013. The AMI division of the electricity and water meter maker brought in RMB1,677.04 million (US$270 million) up to December 2014.
Italian remote advanced metering infrastructure (AMI) company MeterLinq has teamed with US wireless communications solutions provider On-Ramp Wireless to offer enhanced connectivity for critical utility applications.
MeterLinq plans to use the Random Phase Multiple Access (RPMA) as part of MeterLinq’s MeterNet, designed for meter and sensor reading and management, based on UNI TS 11291 standard.
Massimo Cesaro, chief technology officer at MeterLinq, said: “We selected On-Ramp’s RPMA technology in order to provide our customers with secure and reliable communication throughout the network, while reducing their cost of deployment.

“The On-Ramp solution was best suited for MeterLinq’s needs as it offered more coverage and capacity than competitive options and was field-proven with industrial internet of things applications throughout the globe.
He added: “The RPMA technology gives MeterLinq the freedom to design and deliver innovative smart city applications, meeting the most demanding industry requirements such as those of the gas smart metering market in Italy.”

Power distribution networks

MeterNet is used in water, gas and power distribution networks in Italy. It integrates with wired and wireless TLC networks and simplifies the management of AMI for operators and utilities.
On-Ramp’s RPMA network is a wireless system designed from the ground up for low-power, wide-area, machine-to-machine (M2M) communication.
It uses -142 dBm of receive sensitivity, capacity for tens of thousands of devices per infrastructure point and operation in the globally license-free 2.4 GHz IEC band to reach assets in urban, rural or even underground environments.
