Beijing, China-August 8, 2013- Silicon Labs (NASDAQ: SLAB), a leading manufacturer of high-performance analog and mixed-signal ICs, today announced the provision of sub-GHz wireless interconnection technology for Robulink. Robulink is a leading provider of advanced metering infrastructure (AMI) solutions for public utility companies in China, Southeast Asia and Australia. Combined with Silicon Labs ’advanced EZRadioPRO® transceiver, Robulink ’s AMI solution helps utility companies quickly and cost-effectively implement the next generation of smart meters, and communicate wirelessly through smart mesh networks.

Public utility companies adopt new AMI technology for smart grids, and wireless mesh networks are a viable option. Many companies are looking for a two-way communication metering system that goes beyond traditional metering products and can configure time-sensitive services and needs remotely. Sophisticated smart meter networks have many requirements, such as reliability, adaptability, scalability, real-time response, and lower product cycle costs. Robulink's RobuNet â„¢ intelligent mesh network products can provide cost-effective, plug-and-play solutions that can meet the needs of AMI and can reliably adapt to different environments.

To help public utility companies implement a comprehensive AMI system, Robulink provides a three-tier system architecture, including wireless smart meters, wireless concentrators, and back-end energy management systems. Robulink's RobuNet solution is based on an open interface and allows seamless connection to smart meters and concentrators from other manufacturers. It can also be seamlessly connected to any home energy management system and smart appliances. In addition, RobuNet uses the multi-channel frequency hopping technology based on the FCC Part 15.247 specification, which is widely used internationally to enhance noise isolation and reduce interference.

RobuNet mesh network products, such as RDDMRE4 meter communication unit and RCJP242R wireless data collector, integrate Silicon Labs' EZRadioPRO transceiver. In the AMI network, for smart meters, data collectors and data concentrators that enable multiple data communications, advanced RobuNet products will provide reliable RF links and intelligent mesh network routing.

Li Chunhui, President of Robulink, said: "Silicon Labs' EZRadioPRO series products reduce the design complexity of RobuNet mesh network products, increase product competitiveness and accelerate time to market. EZRadioPRO transceivers have RF link budget and adjacent channel suppression capabilities It provides extremely high performance, which is especially critical for the implementation of frequency hopping and ad hoc network technology in AMI and wireless sensor network applications. "

Diwakar Vishakhadatta, vice president of Silicon Labs and general manager of the embedded systems business, said: "As a leading smart meter manufacturer in China, Robulink is a pioneer in developing smart mesh network solutions for AMI. Our EZRadioPRO transceiver is ideal for Robulink The RobuNet product portfolio enables it to develop highly reliable, scalable and flexible wireless smart metering products for China ’s rapidly emerging smart grid and export markets. "

About EZRadioPRO transceiver

The EZRadioPRO series utilizes the industry's highest performance, lowest power sub-GHz transceivers, transmitters and receivers, and is designed to provide maximum transmission range and battery life for power-sensitive wireless systems. It provides 119MHz-1050MHz frequency coverage, and industry-leading RF performance to extend the wireless transmission range, while meeting the industry's most stringent specifications. EZRadioPRO transceiver provides the best sensitivity (-126dBm), transmit output power (+ 20dBm), link budget (146dB) and adjacent channel suppression (58dB). The EZRadioPRO transceiver achieves 50nA sleep / standby current (while maintaining register contents), which can be reduced by 75% compared to current in sleep mode of similar products. This superior energy efficiency brings fewer battery replacements and / or smaller battery sizes for wireless network applications.
