Product overview
The Xingkai MIMO Mesh Network XK-m503e carries voice, data and imagery through a distributed wireless network without a central node. Its MN-MIMO architecture supports point-to-point links, multipoint connections and relay paths, allowing star, line, mesh and hybrid arrangements. The hardware is an airborne communications radio for UAV integration. The described configuration provides two 2W RF outputs, with selectable single-band 2T2R or dual-band 1T2R operation, adaptive modulation and frequency-hopping functions for mobile networking.
The black radio measures 12.5×10.5×3.5cm and weighs 520g in the 2Watts×2 airborne configuration, with four mounting holes. Integration requires a 12-26VDC supply and connections through SMA RF, Ethernet and serial interfaces. Operating current is 1-2.5A at 16.8V, with 0.3-0.5A in standby. Protection is IP55, while IP67/IP68 requires customization. Link planning must account for the specified distance conditions: 100-200 KM under visible conditions and 1-30 KM in urban areas. The 20MHz bandwidth option also determines the quoted average 7mS single-hop delay.
