智能家居以长距离、低功耗技术连接室内和室外

Posted by Marc Pégulu on 03 August 2021


The market for smart home technology continues to grow at a rapid pace. Research from Statista shows that revenue in the European smart home market is projected to reach £18,504m in 2021, growing to £31,682m by 2025, by which time there will be over 97m smart home users.

Across the board, from home automation to smart kitchen appliances and voice assistant-enabled lighting, consumer electronics companies are using the Internet of Things (IoT) to connect everyday devices to the cloud, bringing new opportunities and control for consumers.

The global pandemic has added to this growing trend, causing people to spend more time at home and think afresh about how their home is used and controlled. An April 2021 report by International Data Corporation (IDC) shows that video entertainment, smart speakers and security and monitoring were the top categories in smart home technology in 2020 as householders sought to improve their homes.

As the technology and market has developed, users’ expectations have changed. At first, users were attracted to gimmicky applications but are now more concerned with real world uses that bring actual benefits to their lives. Moving forward, the smart home market will start to see more products that can have a significant impact on the consumer’s day to day life. This wide range of products includes technology and applications such as pet geofencing, which can set boundaries for a pet and warn the owner when it strays outside this area. Other examples could be connected pest traps, telling householders when the trap has been activated.

Consumer-oriented LiDAR Solution Expands Use Cases

Posted by Evaluation Engineering on 27 July 2021

Commercializing advanced technologies is a rising tide that lifts all boats, as any given tech is only as good as the ability to apply it to a purpose. Every advanced tech, from the laser to DSPs, started out as stand-alone products before convergence brought them into more advanced integrated systems. Only by having high levels of integration can an advanced solution, for any application, offer the performance and functionality now expected in the marketplace.

How the IoT Is Shaping Asset Management Solutions

Posted by Marc Pégulu on 22 July 2021



Asset tracking is one of the most widely deployed Internet of Things (IoT) applications. According to Juniper Research, there will be a 27% increase in asset tracking usage over the next five years, growing from 90 million in 2020 to 114 million by 2025. With this increase, IoT solutions need to enable the efficient and reliable monitoring of assets as they move through the production cycle, and often throughout large warehouses and campuses. Having access to reliable location data is increasingly valuable to production managers, reducing the potential for assets to be misplaced or lost entirely during their journey.

许多行业都在投资智能技术,用自动化资产管理解决方案取代传统系统。传统资产管理系统通常耗电大,需要来自众多供应商的多种器件、软件和服务,导致复杂性和成本更高。

At the same time, IoT solutions can be expensive or impractical to implement because of the vast area the asset needs to travel. The main difficulty is linking remote sensors wirelessly to the internet across a variety of sites, both indoors and outdoors – even across different countries – in a seamless manner. The ideal wireless solution should be cost efficient, low power and secure, with the ability to work over long distances. By coupling those features with a low cost and lightweight solution with a standardized infrastructure, the result is a reliable tracking solution that allows logistics operators to reduce downtime during transportation.

众人欢呼:用于体育场馆的 BlueRiver®

Posted by Gareth Heywood on 20 July 2021

当新冠疫情于 2020 年初爆发时,人们普遍认为这一切将在六个月内结束。很少有人预料到全球的现场活动和职业体育赛事会因此而关闭。随着疫情的影响持续到今年,无数音乐会巡回演出被推迟,体育场馆空无一人。我已经买了票去看 2020 年 9 月的 My Chemical Romance 重组巡演,以庆祝我儿子 Max 的 18 岁生日。但它已经两度延期,或许我要等儿子 20 岁生日才能看上这场演出!很多国家正开始开放职业体育赛事,很多像我这样的人都渴望去音乐会看我们喜欢的乐队、喜剧演员和戏剧作品,再次沉浸在观众的集体欢呼和掌声中。用已故巨星 Freddie Mercury 的不朽名言来说,“演出必须继续!”

BlueRiver 和 Audio Over IP

Posted by Gareth Heywood on 08 July 2021

自从 90 年代初至中期在 Dolby Laboratories 开始我的职业生涯以来,我经常被称为“音频专家”。实际上我职业生涯的大部分时间都在研究视频技术,最初是串行数字接口 (SDI),最近则在研究基于 Semtech 屡获殊荣的 BlueRiver® Pro AV 技术的以太网传输软件定义视频 (SDVoE™)。不过我仍对各种音频情有独钟,并特别重视我的产品系列的音频功能,因为这些往往被忽视。

如果 TLP 分析不能保证符合 ESD 标准,为什么它很重要?

Posted by Zhen Li on 07 July 2021

在我加入 Semtech 的九年里,传输线脉冲 (TLP) 基础知识一直是新员工和客户最重要的培训主题之一。许多人问我们为什么总是强调 TLP 分析的重要性并广泛依赖它为我们的客户提供最佳解决方案。TLP 测试无法提供与行业标准(如 IEC 61000-4-2 或 ESDA/JEDEC JS-001)的规定完全相同的波形。它不保证 IC 或系统能通过所需静电放电 (ESD) 测试级别的抗扰性测试。始终建议在 TLP 测试完成后使用 ESD 发生器验证所有结果。那么,为什么我们不直接全部用 ESD 发生器进行测试?毕竟大多数工程师更熟悉和普遍接受 ESD 发生器。要回答这个问题,我认为务必要理解 TLP 不是 IEC 测试的替代或升级,而是作为一种分析工具对 ESD 枪测试进行补充。ESD 枪测试能告诉我们行或不行,但 TLP 可以帮助我们了解为什么和怎样优化。
