- Applications and Uses
Fully compliant with the DVB-RCS2 open standard, the U7920 modem incorporates SpaceBridge’s innovative WaveSwitch™ technology, enabling error-free dynamic switching between TDMA and SCPC return-link waveforms to maximize spectral efficiency and optimize network performance under varying traffic conditions. With support for both Layer 2 and Layer 3 networking, the U7920 provides exceptional deployment flexibility for a wide range of mission-critical and commercial applications, including broadband Internet access, IoT connectivity, homeland security, defense, Enterprise and government communications
The U7920 is a high-performance satellite modem/router designed to deliver reliable broadband connectivity with IP throughput of up to 300 Mbps on the forward link and 20 Mbps on the return link. Supporting the industry-standard OpenAMIP protocol, the U7920 seamlessly integrates with stabilized maritime and mobility antenna systems. Combined with SpaceBridge’s advanced multi-beam mobility and beam-switching technology, compliant with DVB-RCS2 Annex M, the U7920 enables seamless satellite beam transitions while maintaining uninterrupted service. The result is a highly efficient, robust, and secure broadband communications solution for maritime, land-mobile, and other mobility applications operating across HTS and multi-orbit satellite networks.
- 500MHz DVB-S2X Forward Link. Highest spectral efficiency via highly granular MODCOD, low roll off rates and Adaptive Coding and Modulation (ACM)
- EN 301 545-2 V1.2.1 compliant DVB-RCS2 return channels supporting from QPSK to 16QAM and up to 5% roll offs/spacing
- Supports WaveSwitch™, Dynamic Rate/Waveform Assignment (DRA). Automatically generates the return carrier waveform every frame to optimally match user traffic (payload) with either 3D-TDMA or dynamic SCPC while also adjusting block size and MODCOD for maximum spectral efficiency and Hitless (error-free) and dynamic switching between TDMA and dSCPC services every 26.5 msec, conserving satellite bandwidth and power
