我们将持续介绍 LoRaWAN® 协议以及如何转变基于 5G 的下一代网络应用，这是系列博文中的第四篇。该系列博文与 Semtech 的“5G 事实与虚构，以及 LoRaWAN 如何发挥作用”网络研讨会一脉相承。该研讨会的与会者包括 Charter Communications、MultiTech 和 Orange，由 Beecham Research 主持。文章将探讨在网络研讨会的问答环节中观众提出的一些紧迫话题。第一部分中介绍新系列，第二部分访谈 MultiTech 并探索大型 LoRaWAN 网络，第三部分有 Orange 的见解。
This is the third blog in an ongoing series about LoRa® devices and the LoRaWAN® protocol, and its capabilities to transform next-generation networking applications built on 5G. This blog series follows Semtech’s “5G Fact vs. Fiction, and How LoRaWAN Plays a Role” webinar, featuring Charter Communications, MultiTech and Orange, and moderated by Beecham Research, and addresses some of the pressing topics offered by the audience during the webinar’s Q&A. Read the introduction to the new series in part one, and explore large scale LoRaWAN networks in part two, featuring MultiTech.
In part three below, Ronan Le Bras, Head of Technology Strategy at Orange, and Rémi Lorrain, Director of LoRaWAN Networks for Semtech, discuss Cellular devices, network management, regional deployment differences, and roaming/satellite communication.
A year ago, the number of worker-focused proximity alert solutions could be counted on one hand. The need was not particularly great and the use case was very specific. The construction industry is one such area where the safety benefits are compelling. For over a decade, construction companies have been using forms of proximity detection as a means to interrupt at-risk behavior, with one such example being worker-worn systems to detect infrequent unsafe interactions between workers and equipment.
Following its origin 20 years ago, the Device Language Message Specification (DLMS) has become a universal standard for utilities. With a hundred million smart meters using DLMS installed worldwide, it is currently one of the most used smart metering standards today. On June 26, 2020, Semtech was approved by vote to join the board of the DLMS User Association during its recent general assembly.
我们将持续介绍 LoRa® 器件和 LoRaWAN® 协议以及如何转变基于 5G 的下一代网络应用，这是系列博文中的第二篇。该系列博文与 Semtech 的“5G 事实与虚构，以及 LoRaWAN 如何发挥作用”网络研讨会一脉相承。该研讨会的与会者包括 Orange、Charter Communications 和 MultiTech，由 Beecham Research 主持，并解答了网络研讨会问答期间观众提出的一些紧迫话题。在第一部分中阅读新系列简介。
在 LoRa Alliance® 主办、Semtech 主持的网络研讨会中，DLMS（设备语言报文规范）用户协会主席宣布未来将发布用于 LoRaWAN® 协议的第一个 DLMS 配置文件。DLMS 用户协会和 LoRa Alliance 已合作两年多，共同定义一种安全可靠的方式来支持 LoRaWAN 网络上的 DLMS 协议。这种新的配置文件在 2018 年的多次演示中证明了自身可行性，并在 2019 年欧洲公用事业周和 2020 年印度智能公用事业周成功展示。这是通讯方式的一大关键成就，未来将在实施基于 LoRaWAN 的 DLMS 的过程中提供可靠性和互操作性。
We’re well into 2020, and the promise of 5G networking is continuing to lead conversations across the wireless industry. However, as 5G deployments increase, we also see a rise in alternative low power technologies to offer flexible, cost effective power and low bandwidth options for these so-called massive Internet of Things (IoT) deployments. In particular, market demand for solutions based on Semtech’s LoRa® devices and the LoRaWAN® protocol is continuing to increase, including those helping to combat the global COVID-19 outbreak. It has become clear that as 4G and 5G will target low latency and high throughput applications in the near future, LoRa and LoRaWAN-based applications will make up a larger portion of the massive IoT space, led by mobile operators, unlicensed spectrum operators and enterprises across private rollouts. The market is heading toward a Multi-Radio Access Network (Multi-RAN) strategy leveraging complementary standards, including 4G, 5G, LoRaWAN, and others such as Wi-Fi 6.
The LoRaWAN® protocol is especially optimized for low power, wide area networks (LPWANs). It supports secure, bi-directional communication for IoT applications which scale to connect millions of potential devices. As security is a fundamental need in all IoT applications, the LoRaWAN protocol was designed with security in mind, with authentication and encryption built into the specification itself. However, a secure network protocol is only one half of the equation. Deploying a LoRaWAN-based application requires correct implementation of the protocol and a close adherence to recommended practices.
Semtech 的 LoRa® 器件和 LoRaWAN® 开放协议在全球的部署量与日俱增。领先的行业分析公司 IHS Markit 预测，到 2023 年*，预计所有基于低功耗广域网 (LPWAN) 的物联网 (IoT) 应用中将有 43％ 基于 LoRa 设备和/或 LoRaWAN 网络。如今，基于 LoRa 的网关的部署量预计已超过 50 万，它们构成的连接可支持多达二十亿台潜在终端设备**。此外，预计到 2020 年初**，基于 LoRa 的终端节点的部署总量已达到 1.35 亿**，可支持几乎无限的创新用例数量。
Every year, major stakeholders in the North American agricultural network meet at World Ag Expo, one of the continent’s largest annual agriculture events. This year, the event will take place February 11 – 13 in Tulare, one hour south of Fresno in the heart of California’s Central Valley, where farmers produce more than one fourth of all U.S. food and one fifth of all U.S. dairy products.
