U7900 – High-Performance Networking Satellite Modem/Router

Fully compliant with the DVB-RCS2 open standard, the U7900 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 U7900 provides exceptional deployment flexibility for a wide range of mission-critical and commercial applications, homeland security, defense, Enterprise, Cellular Backhaul (CBH) and government communications.

The U7900 is a high-performance L2/L3 satellite modem/router delivering up to 700 Mbps downstream and 50 Mbps upstream throughput. Supporting the OpenAMIP standard and SpaceBridge’s DVB-RCS2 Annex M-compliant multi-beam mobility technology, it enables seamless beam switching and uninterrupted connectivity for maritime, land-mobile, and other mobility applications across HTS and multi-orbit satellite networks. With integrated L2/L3 optimization, the U7900 is ideally suited for VSAT-connected cellular backhaul and enterprise networks, featuring cellular traffic compression, 4G/LTE/5G GTP acceleration, and satellite optimization of IP traffic transported within VLANs and Layer 2 tunnels
