The revolutionary SkyWire™ MDX420 is one of the most innovative satellite products. The system combines the throughput and robustness of a single channel per carrier (SCPC) system with the bandwidth savings of a time division multiple access (TDMA) system.
The SkyWire MDX420 leverages the benefits of each to provide the ultimate in satellite network performance.
The SkyWire MDX420 is the first TDMA broadband satellite system to eliminate the need for high stability references or an expensive central hub with complicated system software. With its revolutionary single hop bandwidth-on-demand capability, the SkyWire MDX420 minimizes system response time to changes in traffic flow. The small efficient burst sizes and ultra low overhead allow the SkyWire MDX420 to provide unprecedented bandwidth efficiency and increased network throughput.
The SkyWire MDX420 system is easy to configure and the auto-everything 10/100/1000 terrestrial data ports provide instant connectivity for any IP application.
Whether you need a TRUE full mesh, a hub and spoke, or a hybrid combination, the SkyWire MDX420 system provides the most cost-effective, easy to use, bandwidth efficient solution available today. And, the system is packaged in a single, secure, one rack unit box.
The published specifications reflect the maximum SkyWire MDX420 performance. Each SkyWire MDX420 can be configured to customer requirements via hardware / software options applied at the factory or in the field.
