Microsemi and Virtual Extension teamed on a two-chip wireless mesh network chipset and reference design. The reference design features Microsemi’s ZL70250 chip scale package (CSP) radio frequency (RF) transceiver for industrial, scientific and medical (ISM) band applications and Virtual Extension’s VE209M wireless mesh controller. Evaluation kits are available immediately from both Microsemi and Virtual Extension.
The ultra-low-power wireless mesh solution 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. The chipset is ideal for energy-harvesting powered or battery-operated wireless mesh applications.
The jointly designed solutions gives network users access to the next-generation of wireless mesh networks with ultra-low-power consumption, without a need to trade off important features.
The Microsemi ZL70250 CSP is an ultra low power RF transceiver operating in the unlicensed frequency bands between 795 and 965 megahertz (MHz). It features a data rate of 186 kilobits per second (kbps) at 2 milliamps (mA) of current to transmit and receive data. The device enables extremely long battery life and miniaturization.
The Virtual Extension VE209M high-performance mesh controllers serves as the main building blocks of a VEmesh node or gateway. 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. 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.
