...expand an existing Advantech Wireless VSAT Hub for a major communications firm in the mid-western USA. This contract has enhanced their ability to offer web-based proof of performance to their customers in hundreds of digital display locations throughout the USA.

Advantech Wireless has provided this redundant forward link by adding DVB-RCS VSAT hub equipment that includes AMT-75 DVB-S2 ACM modulators, IPe-422 IP Encapsulators, ACM adaption units and RF switches. Advantech Wireless also provided the powerful NetManger tool for network optimization, remote monitoring and control. Additionally, Net QoS software was installed. It will improve bandwidth management for their mixed-media traffic.

The customer has migrated from DVB-S to DVB-S2 CCM and now to DVB-S2 ACM since first purchasing their VSAT hub from Advantech Wireless in 2004. The customer’s hub now supports three outbound transport streams (one TS—DVB-S, one TS—DVB-S2 CCM, one TS—DVB-S2 ACM) with all inbound carriers being supported on a single card Advantech MCD (MultiCarrier Demodulator). This configuration is unique in the industry. A major advantage is that the configuration enables the terminals associated with all three TS to statistically share the one pool of inbound carriers among all the terminals. Other systems would have a minimum of three separate pools of satellite bandwidth making the scheduling of the bandwidth significantly less efficient. This feature also enables easy movement of terminals between the different TS without any loss in inbound efficiency. This mechanism allows customers to migrate legacy terminals running DVB-S to DVB-S2 at their own pace without any concern for loss of inbound bandwidth efficiencies.
