Product overview
Sprintlink PTMP combines image, data and control transmission in a wireless system supporting one-to-many and many-to-one operation. Its channels provide one-way image transmission, two-way data exchange and one-way remote control. Video capabilities include 4K support, H265/H264 compression and 200ms screen-to-screen latency. The star network accommodates one master node with up to six slave nodes at 20MHz bandwidth, or two slave nodes at 10MHz bandwidth. Ethernet provides the video interface, with serial and USB interfaces also available.
Built around software-defined radio, Sprintlink PTMP uses OFDM modulation, LDPC forward error correction and a proprietary protocol optimized for video transmission. Adaptive retransmission operates at the underlying communication layer. Continuous channel monitoring enables automatic switching to the least-interfered channel when interference affects operation, while adjustable time slots allocate capacity according to terminal traffic. Both ground and air units measure 77.8 × 47.3 × 23.5mm; the air unit weighs 97g. Operating requirements are 6V ~ 16V and -20°C~55°C.
