Product overview
Guangdong Zhongke Ruitai Intelligent Technology Co., Ltd.’s ZKRT-ZJ01 is a handheld communication terminal integrating relay, base-station and positioning functions. It supports emergency communications in cities, mountainous areas, tunnels and underground spaces where public network access is unavailable. Its decentralized architecture automatically builds multihop links and supports simultaneous voice, data and positioning traffic. Deployment options include carriage by a small UAV, portable backpack use and vehicle-mounted relay operation, while its electrical interface supports communication with UAV and robot ports.
The terminal incorporates a 2400 mAh rechargeable lithium battery, Type-C charging, a 2.0-inch color display, a numeric keypad and an LED status indicator. Weight is ≤350 g including the battery, with IP67 protection and drop resistance. It operates across 120–700 MHz using digital QPSK modulation and supports AES-256 encryption. Line-of-sight distance is ≥100 km at 2–5 W, while operating time is ≥12 hours under the specified high-power transmission 5/90 condition. Operating temperature is limited to -20°C through +55°C.
