Strike Up The Bandwidth For Intelsat Via Comtech EF Data

Intelsat is going to use Comtech EF Data’s award-winning DoubleTalk Carrier-in-Carrier technology and compression in its service targeted to wireless operators, known as RevLinx. RevLinx leverages Comtech technology and compression from Memotec, a subsidiary of Comtech EF Data, to offer the most efficient satellite capacity in the industry. Carrier-in-Carrier is based on Applied Signal Technology’s DoubleTalk bandwidth compression technology. DoubleTalk uses “Adaptive Cancellation.” This is a patented technology that allows the transmit and receive carriers of a full-duplex satellite link to be transmitted in the same transponder space. DoubleTalk Carrier-in-Carrier is complementary to all advances in modem technology, including advanced forward error correction and modulation techniques. As these technologies approach theoretical limits of power and bandwidth efficiencies, DoubleTalk Carrier-in-Carrier utilizes advanced signal processing techniques to provide a new dimension in bandwidth efficiency. DoubleTalk Carrier-in-Carrier allows satellite users to achieve spectral efficiencies (Mbps/MHz ratio) that cannot be achieved with traditional links. Ideal for regions where satellite capacity is constrained, DoubleTalk Carrier-in-Carrier can be used to save transponder bandwidth and/or transponder power thereby allowing successful deployment in bandwidth-limited and power-limited environments. For mobile telephony applications, RevLinx further reduces the amount of capacity required by leveraging Memotec’s optimization and compression technology. Memotec’s new flagship product, the CX-U Series, combines 2G/3G mobile network access optimization and DCME voice compression features together into one compact, carrier-grade unit. It enables operators to reduce network operating expenses by cutting transmission costs and extending the service capabilities for evolving networks—Tempe, Arizona
