SpaceBridge U7400 ASAT MF-TDMA/SCPC Satellite Modem

SpaceBridge U7400 ASAT MF-TDMA/SCPC Satellite Modem

The SpaceBridge U7400 is a rackmount VSAT satellite modem for broadband trunking, cellular backhaul, enterprise connectivity and mobile communications. Supporting download and upload speeds up to 100 Mbps, it operates in hub-less point-to-point SCPC links or ASAT hub-spoke networks. WaveSwitch™ technology automatically switches between MF-TDMA and SCPC return links as traffic demand changes, while built-in acceleration, compression and QoS improve satellite bandwidth efficiency.
