LoRa

Semtech 通过创造创新技术来推动全球变革，努力推动更智能、更清洁和更互联的地球。具体而言，利用 Semtech 的 LoRa® 器件和 LoRaWAN® 标准的物联网 (IoT) 应用支持广泛的解决方案，以提高效率并减少浪费。

自然灾害往往没有预警，并会造成难以估量的后果。在发生飓风、龙卷风、地震、洪水或野火等灾害后，社区需要资金援助来清除碎片、提供救生紧急保护措施和恢复公共基础设施。最近通过的《2021 年美国救助计划法案》正是响应了社区的需求。该法案为联邦紧急事务管理局 (FEMA) 的救灾基金拨款 500 亿美元，以帮助州和地方政府应对重大灾难或紧急情况并灾后重建。

IotaComm, TEKTELIC and Semtech recently announced a product development and licensing agreement to develop a gateway based on the LoRaWAN® standard and Semtech’s LoRa® chipset.

After more than a year of lockdown, schools are now reopening and faced with the difficult challenge of ensuring a safe learning environment, or risk returning to remote learning.

LoRa Cloud™ services enhance Semtech’s LoRa® devices by simplifying secure device onboarding with the LoRaWAN® standard, modem management and power optimized geolocation. The Internet of Things (IoT) is about connecting devices to the internet and LoRa Cloud services makes that process much easier and more cost-effective.

When it comes to connecting Internet of Things (IoT) devices, there is no one-size-fits-all protocol to address all use cases. Each connectivity option has trade-offs between power consumption, bandwidth and range.

随着物联网（IoT）技术和信息物理系统 (CPS) 的快速发展，机器人已在众多行业中得到广泛应用。工业机器人不仅常见于电子、汽车、化工等行业，也越来越多地用于家庭、酒店、餐厅等环境中的服务功能。近年来，全球服务机器人技术取得了长足的进步和发展，在家庭、教育、公共服务、医疗等领域实现了一系列突破性的应用，为创造更好的生活和进一步提高生产效率奠定了基础。

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.

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.

让地理定位技术成为任何类型的联网设备都能提供的本地服务，何乐而不为？如果有一种解决方案，能让电池寿命超过现有蜂窝网络解决方案的 10 倍，并且客户能仅在需要时付费使用地理定位服务，岂不妙哉？地理定位的未来已经到来。
