Company Profile
Shanghai Quanray Electronics Co., Ltd. An innovative enterprise focused on passive IoT technology.
Driven by the vision of “Green Connectivity, AI Empowerment,” we leverage battery-free sensing RFID chips and tags to build zero-carbon, low-cost IoT data infrastructure. By transmitting item identity, status, and trajectory information to the cloud via 4G/5G networks, we provide sustainable and massive data streams for AI systems, enabling enterprises to achieve intelligent and low-carbon asset management cycles.
Main Business
Quanray is an innovative provider of Green Passive IoT solutions. The company specializes in designing, manufacturing, and supplying battery-free, ultra-low-power RFID chips, tags, readers, and hardware solutions. Our primary focus is on building pervasive, sustainable, and cost-effective data acquisition infrastructure for the Internet of Things (IoT) by leveraging three core passive technologies: Near-field Passive IoT: Advanced RFID+ chips and tags (UHF/HF/LF/DF) that integrate sensing capabilities (e.g., temperature, tilt) for identification and close-range monitoring. Local-area Passive IoT: Battery-free Bluetooth AoA (Angle of Arrival) systems for centimeter-level precision indoor positioning and asset tracking without batteries. Wide-area Passive IoT: Ambient IoT (AIOT) solutions that utilize ambient energy (e.g., via 5G-A networks) for long-distance, massive-scale device connectivity without traditional power sources.
Battery-free ePaper Tag
Description:
The battery-free ePaper tag is designed base on Quanray’s UHF chip. It features RF energy harvesting to power ePaper updates without batteries.
BT01 (Battery-free BLE Beacon) Description: This passive BLE 5.3 beacon achieves a broadcast range of up to 120 meters in open areas and operates solely on solar power, requiring no battery replacement. Designed to resist metal interference, it can be mounted directly on metal surfaces. Its beacon data, received by Bluetooth AoA gateways, enables asset inventory, location tracking, and access management for applications in automated warehousing and mobile equipment tracking. Application: Auto Inventory: Bluetooth gateways enable contactless warehouse stock counting. Mobile Tracking: Provides zone-level positioning for movable assets. Smart Logistics: Passive beacon simplify inbound/outbound management without RFID’s angle/distance limits.
