什么是 LoRa®?

LoRa(long range 的缩写)采用的扩频调制技术源于啁啾扩频 (CSS) 技术。Semtech 的 LoRa 是一种长距离、低功耗无线平台,是事实上的物联网 (IoT) 无线平台。LoRa 器件和网络(如 LoRaWAN®)使得智能物联网应用能够帮助解决地球面临的能源管理、自然资源减少、污染控制、基础设施效率、防灾等艰巨挑战。Semtech 的 LoRa 器件已在智慧城市、家居和建筑、社区、计量、供应链和物流、农业等领域实现了数百个成功应用案例。LoRa 网络已覆盖 100 多个国家/地区的数亿台器件,致力于打造一个更智慧的地球。

Semtech 的 LoRa 技术应用

Technology Ecosystem

LoRa devices and the LoRaWAN standard offer compelling features for IoT applications including long range, low power consumption and secure data transmission. The technology is utilized by public, private or hybrid networks and provides greater range than Cellular networks. Deployments can easily integrate into existing infrastructure and enable low-cost battery-operated IoT applications. Semtech's LoRa chipsets are incorporated into devices manufactured by a large ecosystem of IoT solution providers, and connected to networks around the globe. Simply stated, LoRa connects devices to the Cloud, providing a "voice" to things — making the world a better place to live, work and play. 

LoRa 和 LoRaWAN 的区别

LoRa 和 LoRaWAN®

LoRa is the silicon developed by Semtech, and LoRaWAN® is a standard for interoperability managed by the LoRa Alliance®, a non-profit technology alliance of which Semtech is a founding member and board sponsor. While most IoT use cases can be solved by the vast LoRaWAN ecosystem, customers may consider LoRa PHY with a proprietary network implementation on top. An example of this is the Amazon Sidewalk network for smart home and community applications. With over 208 million end nodes deployed, there are use cases for LoRa in nearly every vertical market. 

LoRa 器件:连接无所不在

LoRa 器件专为物联网通信而设计,可实现远程终端节点和低功耗广域网 (LPWAN) 之间的连接,交付数据给分析应用程序。

设备

LoRa 调制:LoRa 技术是物理 (PHY) 硅层或无线调制,用于创建远距离通信链路。

收发器和终端节点:配备 LoRa 器件的收发器可嵌入到终端节点或传感器设备中,适用于众多行业应用。

Picocells & Gateways: Sensors capture and transmit data to gateways over distances near and far, indoor and outdoor, with minimal power requirement.

网络

Network Server: Gateways send information via Wi-Fi, Ethernet or Cellular to the network server, which is responsible for network management functions like over-the-air activation, data de-duplication, dynamic frame routing, adaptive rate control, traffic management, and administration.

应用

Application Servers & Cloud IoT Services: Applications interpret the data collected by sensors, applying techniques like machine learning and artificial intelligence to solve business problems for a smarter planet.

LoRa 云服务

LoRa Cloud™ Services

Semtech 的 LoRa Cloud 服务提供易于使用的“成分”,解决方案提供商可以利用这些“成分”以更少的开发开销更快地创造价值。此服务方便开发者快速构建物联网解决方案。开发者可利用多模式定位功能(包括基于 Wi-Fi、GNSS 和 LoRaWAN 地理定位),无需从头开始构建解决方案,开发更简单。LoRa Cloud 服务的设计初衷就是支持灵活部署、经济实惠、易用。
