EMC Satcom’s carrier overlapping technology saves full transponder in Asia

10 May 2010

EMC Satcom Technologies GmbH established a new landmark in satellite link optimization by achieving a symmetrical 155/155Mbps circuit inside a single transponder and in turn liberating a full 72MHz transponder. 

The existing STM-1 in Asia-Pacific was utilizing a 72MHz transponder of the outbound carrier 155Mbps and another 72MHz for the inbound carrier 155Mbps.  By placing EMC Satcom’s NRS Bandwidth Booster at each end of the link a full 72MHz has been cancelled allowing the existing symmetrical 155/155Mbps STM-1 to operate within one transponder only. 

“The implementation of the NRS in the customer’s network was seamless with the technical knowledge and expertise of our engineers allowing us to be on top of every aspect of the implementation.  The final result was a perfect match to our pre-installation theoretical analysis”, highlights Federico Fawzi, Head of Engineering. 

This optimization and releasing of satellite capacity equates to over $2million a year in savings for the customer. 

“With the cost of satellite capacity higher than ever our customer was keen to reduce their opex and we were able to achieve that with a minimum outage and minimal change to the link architecture”, explains EMC Satcom’s Managing Director, Clemens Wolbers. “There are many other satellite STM-1s ready to benefit from the NRS’s cost reduction capabilities.” 

The NRS Bandwidth Booster is available for satellite MHz bandwidth cancellation at 12MHz, 25MHz, 36MHz and 72MHz and is completely modulation agnostic being able to work with all satellite modems.  In addition to SCPC links, the NRS works with all brands of TDMA hubs allowing the MHz currently allocated to the inbound channels to be saved.  As a hub only installation the NRS achieves these savings without any physical changes to the remotes making it ideal for networks large or small.
