2025年华为园区网络星闪SLE物联数采技术白皮书-华为

Core Insights - The article introduces Huawei's Sparklink Low Energy (SLE) technology, which aims to provide efficient and reliable wireless data collection solutions for IoT scenarios, addressing the limitations of traditional short-range communication technologies in terms of connection density, bandwidth, latency, and power consumption [1][13]. Group 1: Technology Overview - SLE technology is designed to meet the diverse data collection needs in various IoT applications, including smart homes, smart manufacturing, and the power industry [1][3]. - The SLE technology architecture consists of three layers: access layer, basic service layer, and basic application layer, supporting various communication scenarios [1][15]. - The access layer supports multiple communication scenarios, including G-T node communication, G-G node communication, and T-T node relay communication, utilizing modulation methods such as GFSK, QPSK, and 8PSK [1][19]. Group 2: Advantages and Comparisons - Compared to traditional technologies like Wi-Fi, BLE, and LoRa, SLE offers significant advantages, including an air interface rate of 12 Mbps, which is six times that of BLE, and an 8 dB improvement in coverage capability [2][10]. - SLE supports up to 20 concurrent connections and employs dual authentication and national encryption algorithms (SM4/AES), enhancing security while maintaining comparable power consumption to similar technologies [2][10]. Group 3: Application Scenarios - A typical application focuses on data collection in the power industry, providing a unified access solution that meets the low-power access needs of narrowband sensors while supporting high-bandwidth terminals for data transmission [3][11]. - The SLE technology is positioned as an efficient domestic solution for IoT data collection, with potential applications in smart manufacturing and smart cities [3][11].
