Semtech releases chip for Wireless Smart Lighting Applications

  • May 30, 2010

May 30, 2010 - Semtech announced a two-chip wireless mesh network chipset that brings a new level of performance and signal robustness to smart lighting applications.The chipset pairs Semtech’s SX1211 transceiver for industrial applications with Virtual Extension’s VE209S wireless mesh controller. Smart lighting designers now have a low-power, high-performance solution for building a wireless sensing network with no single point of failure and very robust signal processing. This low-power chipset is also perfectly adapted to battery-operated applications with a 10-year operating lifetime.The SX1211 is part of Semtech’s complete platform of ISM-band transceivers and is optimized for asynchronous sensor network designs in unlicensed ISM frequency bands (868-870 MHz and 902-928 MHz). The device features the industry’s lowest receiver current consumption (<3mA) for increased battery life. All of the transceiver’s major RF communication parameters are programmable and can be configured dynamically, with RF output power programmable up to +12.5 dBm.The VE209 family of high-performance mesh controllers serves as the main building blocks of a VEmesh unit, either a gateway or a node. These mesh controllers have the necessary internal elements for performing all the interfaces and network management. VEmesh units provide highly reliable bi-directional communication and best-in-class range and coverage for distributed monitoring and data collection of sensor and metering systems. All VEmesh nodes also act as relays to retransmit data from other units in order to create a modular solution with no practical limitation to the number of nodes or size of coverage area. Key Features of the Semtech - Virtual Extension ISM Wireless Mesh Solution

  • Fully bi-directional
  • Built-in unicast and broadcast capabilities
  • Farthest range in class
  • Fastest response in class – lowest and most predictable latency
  • Secure (frequency diversity) and resistant (space diversity) to multipath fading and propagation changes
  • No-knowledge, no-training installation and maintenance
  • No need for managing software
  • Instant addition and removal of nodes, with no network downtime
  • Practically unlimited number of hops, thousands of nodes per network
  • Highly scalable: robustness and network range increase when the network expands.
  • AvailabilityEvaluation kits (order code: SX1211MESH-868 and SX1211MESH-915) are available immediately from Semtech. Semtech 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.
