原标题:联合厂商Quandic推出基于Semtech SX1276 LoRa之Beacon追踪器方案

  

  第三方Quandic 基于Semtech SX1276 LoRa架构下之Beacon 追踪器方案是快意科技致力于 RFID (无线射频辨识)与LoRa技术的研发与制造,目前主要应用于物联网(IoT)领域上来提供各种不同的领域如物流仓储、医疗、零售、制造、交通运输、农业…等提供更便利、更有效率、或更安全的环境。此产品之工作原理为使用布建于需要监控范围内定点的快意科技Beacon信标产品QIB100提供坐标信号传送至配置于受监测人员上之追踪器QIT100后再经LoRa收发器之长距离且抗噪声之通讯特性发送坐标及数据至双信道LoRa 接收读取器QIR100。而此接收器在将所接收到的节点信息送至后台供追踪知道人员之位置状态及状态,并可藉此远程定位系统迅速找到人员。故此产品可以大大减少如看护中心或是学校工厂等环境监控的人力及时间。

  【SX1276】

  137MHz to 1020MHz Long Range Low Power Transceiver

  The SX1276/77/78/79 transceivers feature the LoRa® long range modem that provides ultra-long range spread spectrum communication and high interference immunity whilst minimising current consumption.

  Using Semtech’s patented LoRa modulation technique SX1276/77/78/79 can achieve a sensitivity of over -148dBm using a low cost crystal and bill of materials. The high sensitivity combined with the integrated +20dBm power amplifier yields industry leading link budget making it optimal for any application requiring range or robustness. LoRa also provides significant advantages in both blocking and selectivity over conventional modulation techniques, solving the traditional design compromise between range, interference immunity and energy consumption.
