Product overview
The Xingkai XK-F358 Drone SDR Airborne 2*10W MIMO MESH Radio Communication Module provides airborne broadband links for voice, data and imagery. Its distributed, centerless architecture supports point-to-point, point-to-multipoint and multipoint-to-multipoint communication, with dynamic routing and multi-hop relay. The radio combines two 10W RF outputs with MN-MIMO, space-time coding, spatial diversity, beamforming and spatial multiplexing. Channel bandwidth options are 1.25/2.5/5/10MHz, with adaptive data rates of 1–70Mbps at 10MHz. Single-hop communication distance is 100–300 KM under visible conditions and 1–30 KM in urban areas.
The 10Watts×2 airborne configuration measures 12.7 × 11.0 × 3.3cm, weighs 635g and has four mounting holes. Its integration connections include two TNC RF interfaces, one to three RJ45 Ethernet interfaces, WiFi AP, serial connections and push-to-talk auxiliaries. Power can be supplied by a twist-lock battery or main cable. The supply rating is 18–36VDC; operating current of 3–6A and standby current of 0.7–0.9A are specified at 16.8V. Protection is IP66, with customized IP67/IP68 options, and the operating temperature range is −40°C to +80°C.
Network expansion through public network routing/4G LTE, WB-NB integration, fiber or satellite is optional. Optional video extensions provide low-delay HDMI/SDI/CVBS interfaces with 4K/2K/1080P/720P/D1 formats. Web-based management, a development API and SNMP support integration and control, while separate indicators show network status and link quality. Local and remote management covers radio settings, spectrum scanning, network topology, traffic and temperature/voltage/jamming monitoring. Remote silence and wake-up are optional. Average single-hop delay is 7mS at 20MHz bandwidth, a measurement condition distinct from the listed channel bandwidth options.
