Completion of the cycle to IP-centric networking
Only a few years ago, the dominant satellite network equipment technologies, with the related RF chain supporting this equipment, were based on legacy network protocols. With the leading VSAT manufacturers all delivering IP centric equipment today, the service providers and private network architects made significant new investments in 2007, while completing the long-term cycle by discarding the older, less efficient and unreliable (for broadband) products of the past.
Major new technical advancements
Hub Optimized Gateway For both the satellite video and the satellite data networking markets, the long awaited DVB-S2 standard began making serious inroads, with deliverable products in 2007 and phenomenal payback periods for users of the new technologies. Nevertheless, for data networking traffic, DVB-S2 only optimizes the physical layer of the network. When combined with a new generation of acceleration and bandwidth optimization products at the network layer of the link, early adopters and pragmatic buyers were rewarded with drastically lower cost per bit ratios over the last 12 months, despite some increases in satellite capacity costs. Thus, forward-looking customers were quite confident in making large capital investments during 2007 to obtain years of operational paybacks into the future. We expect that trend to continue with increasing amplitude in 2008 and beyond.
Editor’s Note: DVB-S, the original Digital Video Broadcasting forward error coding and modulation standard for SatTV, was accepted back in 1995 and this is used by satellites serving content all over the globe. DVB-S2 is an enhanced spec developed in 2003, ratified by ETIS in March of 2005 and replaces the DVB-S standard. Expectations are that DVB-S2 will be used for all new digital satellite multiplexes in Europe and satellite receivers will be able to decode both of the specifications. DBV-S2’s main use today is for HDTV distribution and the spec development actually coincided with HDTV and H.264 (MPEG-4) video codecs debut!
Emergence of the broadband mobility market
One of the great historical strengths of satellite technology is wide and ubiquitous coverage. For decades this has served the narrowband/MSS equipment manufacturers and service providers extremely well. Now, with the emergence of a common networking protocol and efficient use of spectrum, broadband applications are economically reaching the masses at both fixed (predictable) prices and on a variable price basis. In 2007, this dual dynamic resulted in significantly higher market adoption rates for maritime broadband, aircraft Internet access and military satcom on the move (SOTM). This has led to creative use of the latest satellite equipment technologies and establishment of new service providers that did not compete in broadband access prior to these developments. A good example of this phenomenon is ARINCs (Aeronautical Radio, Inc.) positive emergence in the private aircraft broadband services market using both new types of technologies (i.e. XipLink XE Embedded Acceleration) and a sound economic operating model for delivering these services at a profit.
