Microsemi and Virtual Extension Collaborate

April 11, 2013

The two companies have developed a two-chip wireless mesh network chipset and reference design that bring a new level of performance and signal robustness to applications requiring networks with high performance and ultra-low power consumption.

ALISO VIEJO, CA /PRNewswire/ -- Microsemi Corp., a leading provider of semiconductor solutions differentiated by power, security, reliability, and performance, and Virtual Extension, a leading wireless mesh networks company, based in Beit-Dagan, Israel, announced a two-chip wireless mesh network chipset and reference design that bring a new level of performance and signal robustness to applications requiring networks with high performance and ultra-low power consumption. The reference design features Microsemi's ZL70250 chip scale package (CSP) radio frequency (RF) transceiver for industrial, scientific, and medical band applications and Virtual Extension's VE209M wireless mesh controller. The combination provides system engineers with an ultra-low power, high-performance solution to build wireless sensing networks with no single point-of-failure and extremely robust operation. This chipset is designed to be the ultimate choice for energy-harvesting-powered or battery-operated wireless mesh applications.

"Our jointly designed solutions allows network users to have access to the next-generation of wireless mesh networks with ultra-low-power consumption, without a need to trade off important features," said Stephen Swift, senior vice president and business unit manager of the Ultra Low-Power Products Group at Microsemi. "Demand for low power and high performance wireless sensor networks is growing quickly and we will continue to collaborate with industry leaders such as Virtual Extension to deliver leading-edge solutions to meet changing industry needs."

"This reference design provides our customers with a proven path towards high performance, low power consumption and low cost network solutions," said Yariv Oren, CEO of Virtual Extension. "Microsemi brings the ultra-low-power transceivers that, when combined with our 'diversity path mesh' technology, results in networks that are easier to design and build, are much more robust, easier to install and maintain, and can easily use energy harvesting."

The ZL70250 CSP is an ultra low power RF transceiver operating in the unlicensed frequency bands between 795 and 965 MHz and delivers a data rate of 186 Kbps at 2 mA of current required to transmit and receive data, enabling extremely long battery life and miniaturization. These two features are particularly important for applications using energy harvesting and battery-powered wireless sensor networks.

VEmesh networks provide highly reliable bi-directional communication and best-in-class range and coverage for distributed monitoring and data collection of smart metering, smart lighting and wireless sensor networks. The modern synchronized-flooding principle that is used allows for wireless mesh networks with space diversity and eliminates the need for self-forming, self-healing and human involvement. All VEmesh nodes act as end-nodes and as relays, to retransmit data in order to create a mesh modular solution, precluding also the need for dedicated routers. The VE209 family of high-performance mesh controllers serves as the main building blocks of a VEmesh node or gateway.

Key Features of Microsemi-Virtual Extension Ultra-Low-Power Wireless Mesh Solution:

  • Ultra-low-power peak power consumption, ideal for energy harvesting or battery-operation
  • Fully bi-directional
  • Unlimited number of nodes/hops: (practically 1000s/20)
  • Fast response with low and predictable latency
  • Very high robustness, resiliency to interference (no dead spots)
  • Requires little to no maintenance, as nodes can be added and removed without any centralized changes to the network
  • Built-in unicast and broadcast capabilities

Evaluation kits (order code: EVK-ULP) are available immediately from Microsemi and Virtual Extension. Microsemi offers comprehensive design assistance, including field- and factory-based support. Data sheets, volume pricing, and delivery quotes, as well as evaluation kits and samples, are available online. For customized ready-to-use modules based on the chipset, please inquire with Virtual Extension at info@virtual-extension.com.
