Product overview
The Xingkai 2*2W Airborne MIMO Mesh Radio XK-F355 provides a communications subsystem for airborne, ground and maritime networks, carrying voice, data and video between distributed nodes. Its decentralized architecture supports dynamic routing and multihop relaying across star, linear, mesh and hybrid arrangements. Nodes can discover and connect with one another without a central controller. For procurement, the product is an airborne radio rather than a flight platform or airframe kit; its role is to connect equipment within a mobile broadband network.
The black radio measures 110 × 62 × 20 mm and weighs 160 g, providing a compact package for installation where space and mass matter. Integration connections include two TNC RF interfaces, Ethernet, serial communication, WiFi AP, GPS/BeiDou and DC input. It requires DC 9–28V power. Configuration choices affect capability: 40MHz bandwidth, carrier aggregation and encryption are optional, while IP67/IP68 protection requires customization beyond the listed IP66 rating. Communication distance depends on surroundings, with separate intervisibility and urban ranges; the listed transmission speeds also depend on channel bandwidth.
