Amazon’s Sidewalk Unmasks Hidden Value Of Mesh Networks
The benefits of having devices that are nearly always connected has never been more obvious than it is today. In that regard, cellular networks and technologies like 5G have proven to be incredibly valuable. At the same time, there’s no denying that integrating cellular connectivity into every connected device we own isn’t a reasonable option for both practical and economic reasons. It’s simply too expensive and too challenging to do that. Various flavors of WiFi and even Bluetooth, of course, have also become an essential part of the connectivity fabric and are a great solution for many devices and applications. Read more
Satellite connectivity bridges gap to underserved IoT markets
尽管 LoRaWAN® 物联网地面专用和公共网络已在 160 多个国家/地区大规模推出，但许多地区仍没有连接，并且 LoRaWAN 网络服务提供商在这些偏远地区投资的经济回报很低或没有。卫星运行 LoRaWAN，还具有 Semtech 的长距离跳频扩频 (LR-FHSS) 新数据速率。该技术已于 2020 年底获得 LoRa Alliance 的认可，为地面和星 LoRaWAN 网络提供独特的合作机会，带来无处不在的覆盖。阅读更多
瑞士邮政使用 SmartButton 器件转变邮政服务
瑞士邮政正在改变其为偏远村庄的家庭提供邮政服务的方式。在这些地方设立邮局很不划算，瑞士邮政推出了 100,000 个使用 Semtech LoRa 的 SmartButton，方便人们一键按需订购邮政服务。阅读更多
利用 LoRa® 实现卫星通信
Low-cost and low-power satellite connectivity technology built directly with smart sensors will kick-start a second IoT revolution. With LoRa®, a device-to-Cloud platform built for applications requiring long range, low power, incorporated into satellites, smart sensors can enable two-way communications to and from satellites in Low Earth Orbit (LEO). LoRa can run on Very High Frequency (VHF) frequencies for uplink and downlink to satellites from the ground. Read more
