Core Viewpoint - Huawei's Mate 80 series has launched the industry's first 700MHz emergency communication feature, enhancing communication capabilities in disaster scenarios and positioning itself as a leader in integrated communication functions [2][18]. Summary by Sections 1. Introduction of 700MHz Emergency Communication - Huawei announced the Mate 80 series featuring 700MHz emergency communication, capable of penetrating three floors and covering over 13 kilometers, aimed at providing communication during disasters [2][18]. 2. Understanding "No Network Communication" - "No network communication" refers to the ability to communicate without traditional network infrastructure, relying on direct, decentralized connections between devices [2][4]. - This technology has gained attention due to its potential to maintain communication in extreme environments where traditional networks fail [3][21]. 3. Technical Mechanisms - The core principles of no network communication include direct device-to-device (D2D) communication and mesh networking, allowing devices to form ad-hoc networks for data transmission [5][6]. - Devices can communicate directly using protocols like Bluetooth and Wi-Fi Direct, bypassing traditional network infrastructure [5][6]. 4. Market Trends and User Demand - The rise of no network communication is driven by market saturation in traditional hardware features, prompting manufacturers to seek new selling points that enhance user experience [8]. - Increasing outdoor activities and the need for reliable communication in weak network areas have made no network communication a critical feature for consumers [8][21]. 5. Competitor Developments - Other manufacturers like OPPO and Vivo have also introduced their versions of no network communication, showcasing various capabilities such as long-distance communication and emergency SOS features [9][12][14]. - Xiaomi's "Starry No Network Communication" system utilizes a distributed network approach, allowing devices to act as signal relay nodes, enhancing communication stability [14][17]. 6. Future Prospects - The future of no network communication lies in its ability to complement existing cellular networks, providing reliable communication in areas where traditional networks are inadequate [20][22]. - This technology is expected to evolve into a secondary communication channel, ensuring connectivity in extreme conditions and enhancing safety in various applications [21][22].
