世界上超过 80% 的人口（即 66.48 亿人）拥有智能手机，所有这些手机都发出低水平的射频 (RF) 辐射。特别是 5G 手机，为满足对更可靠连接和更大带宽的需求，它们在设计上采用了高性能射频器件并配置有更多天线。
5G
从智能手机和笔记本电脑，到自动取款机和在线购物，数据一直在流动。随着消费技术和行业创新的进步，预计到 2025 年，全球数据创建量将增长到 175 泽字节 (ZB)。其中近 53ZB 的数据将被实时消耗——相当于一次流式传输 5830 亿个 4K 视频的数据——这将使当前的网络基础设施不堪重负。
信号完整性是每个数字平台的核心支柱，因此光解决方案对于连接和推动数字时代至关重要。每当有人打开网页或使用已连接的器件时，数据都会从 A 点移动到 B 点（通常是通过光纤）。随着行业和消费者对高质量互联网、快速上传与下载的需求不断增加，现在光纤上网用户已占固定宽带用户的 32%，在过去十年中增长了 20%。支持数据使用和云计算的数据中心和企业网络公司需要高性能的光互连技术，以便在不牺牲效率和速度的情况下最大限度地减少成本和功耗。
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.

我们已经进入 2020 年，5G 网络的前景将继续引领整个无线行业的对话。但随着 5G 部署的增加，我们也看到替代低功耗技术的兴起，为这些所谓的大规模物联网 (IoT) 部署提供灵活、低功耗和低带宽选项。特别值得注意的是，市场对基于 Semtech 的 LoRa® 器件和 LoRaWAN® 协议的解决方案的需求不断增加，包括那些有助于对抗全球新冠爆发的解决方案。很明显，随着 4G 和 5G 在不久的将来侧重于低延迟和高吞吐量应用，基于 LoRa 和 LoRaWAN 的应用将占据由移动运营商、免授权频谱运营商和私人推广企业主导的庞大物联网空间的更大部分。市场正朝着利用互补标准（包括 4G、5G、LoRaWAN 和 Wi-Fi 6 等其他标准）的多无线电接入网络 (Multi-RAN) 战略迈进。

There can be no doubt that Wi-Fi and LoRaWAN® are very different networking protocols. Wi-Fi’s technology excels at short to medium range, high throughput and low latency communication, while LoRaWAN-based networks serve long range communication with small amounts of data. Despite these differences, these two networking protocols share some very similar characteristics, address largely complementary use cases and are often used in very collaborative ways.

There is little doubt that 5G will play a major role in our society’s future. As a veteran of the telecommunications industry who has developed generations of hardware and software, I have a deep appreciation for what 3rd Generation Partnership Project (3GPP) is doing with 5G, and am excited to see how it will change lives in the years to come.

I have just returned from Mobile World Congress (MWC), the most anticipated mobile industry event of the year with 109,000 visitors from 198 countries, and I’m in awe of the pace of innovation in the Internet of Things (IoT) market, as well as the speed at which technologies are rapidly evolving to market-ready solutions. This observation could not be more true for Semtech’s LoRa® devices and wireless radio frequency technology (LoRa Technology).
