物聯網裝置有限的使用壽命和相應的維護成本，一直是普及使用的障礙。無線傳輸對於大規模物聯網部署至關重要，但無線電通常是無線感測器節點最耗電的零組件。HaiLa 將這些裝置中的無線電以HaiLa 反射晶片取代，解決了低功耗物聯網感測器的電池壽命和維護問題。 HaiLa 的零無線電技術使數據能夠使用現有的環境無線信號「搭便車」，獨立在協議之外，對主要無線網絡頻道的干擾最低，最後降低了擁有成本和電力消耗，因此減少了廣泛部署物聯網的整體碳足跡。 The limited lifetime and corresponding maintenance costs of IoT devices remains a challenge to widespread adoption. Wireless transmission is essential for scaled IoT deployment, yet wireless radios are commonly the most power consuming components of wireless sensor nodes. HaiLa has solved the issue of battery life and maintenance in low- powered IoT sensors by replacing the radio in these devices with a HaiLa reflecting chip. HaiLa’s radioless technology enables data to “catch a ride” onto the existing ambient wireless signals, independent of protocol with minimal interference to the primary wireless network channel. Ultimately, this reduces the cost of ownership, energy consumption thus reducing the overall carbon footprint for widely deployed IoT. 🌟 Learn more Garage+ Must-see Startups: https://www.garageplus.asia/2022_mustsee
