Product overview
The Xingkai Broadband Handheld MIMO MESH RADIO XK-F357 provides mobile IP communications for voice, data and video, including air-to-air, air-to-ground and unmanned-vehicle applications. Its distributed architecture forms a network without a central node, using same-frequency networking and multi-hop relays. Point-to-point, multipoint and hybrid arrangements accommodate moving nodes and changing topology. Spatial multiplexing, space-time coding, diversity and transmit/receive beam forming support the radio architecture, while spectrum scanning and optional frequency-selection, hopping and roaming functions provide channel-management choices.
The handheld configuration measures 19×6.8×3.8cm and weighs 0.769kg with an 11.1V/6.8AH battery, or 22×6.8×3.8cm and 0.982kg with an 11.1V/10.2AH battery. The OEM module occupies 10.1×5.4×1.9cm and weighs 123.5g, with an SMP RF connector. Integration provisions include four mounting holes, Ethernet, serial connectivity, USB and push-to-talk connections; power comes from a twist-lock battery or main cable. IP66 protection is specified, with IP67/IP68 available through customization. Communication distance depends on visibility and urban conditions, and 40MHz bandwidth is optional.
