Tausync’s ViuLinx FX Series provides long-range UAV communications in 2W, 5W, and 10W configurations. Operating at 1.4 GHz, the family supports point-to-point and point-to-multipoint networks, with specified communication distances of 50 km or 100 km for the 2W model, 150 km for the 5W model, and 200 km for the 10W model.
All three models combine OFDM modulation, 10 MHz bandwidth, TDD duplexing, and LDPC forward error correction. BPSK, QPSK, and 16QAM constellation modes support downlink throughput of 2–8 Mbps, alongside a 600 kbps uplink.
The 2W and 5W models feature receiving diversity, dynamic antenna switching, and adaptive modulation and coding. The 10W model provides a bidirectional TDD link for video, telemetry, and RC data. Encryption specifications list DES56 and optional AES-256 across the series, with FPGA-based AES-256 implementation also specified for the 5W and 10W models.
Model-dependent interfaces include Ethernet, serial, TTL/RS232, S.BUS, PPM, and power connections. Active- and passive-cooling options are available for the 2W and 10W models, providing a choice of size, weight, and operating temperature to suit different UAV integration requirements.
