'DVB-S2 is so powerful that in the course of our lifetime, we will never need to design another system' - Barry Tew (DVB)
The ViaSat® Star Nova S2 system is a two-way, bandwidth-on-demand broadband VSAT system designed around the DVB-RCS standard for service providers, ISPs, and corporate networks. Star Nova S2 brings more efficiency and higher data rates to the market than other TDMA systems. The Star Nova S2 Broadband VSAT System combines broadband access and a high-speed return channel to satisfy bandwidth-intensive applications using IP data over any fixed satellite.
Since their introduction, LinkStar® VSATs have been built on a foundation of open standard DVB technology, including a DVB-S or DVB-S2 forward link and DVB-RCS return link. A LinkStar-S2 terminal can operate in either of two over-the-air downloadable software personalities. The DVB-RCS software enables interoperability with other manufacturers. The standard LinkStar e-ATM software includes additional advanced features not included in the DVB-RCS standard.
The Star Nova S2 system compliant technology includes advanced LDPC (Low Density Parity Check) coding for ultra-low Eb/No performance near Shannon's theoretical limit along with 8PSK coding for bandwidth reductions up to 30% below traditional values. t offers satellite link speeds up to 81 Mbps on the outbound channel and up to 4.2 Mbps on the inbound channels to the hub. With this high inbound channel capacity, remote sites can be server locations, content providers, multimedia sources, video teleconferencing participants, and corporate headquarters.
KEY POINTS:
Multiple inbound access schemes to support a wide range of applications
Bandwidth on Demand (BoD)
Committed Information Rate (CIR)
Application-triggered BoD/CIR
CIR reallocation
Slotted Aloha
Frequency hopping across carriers
Acceleration and compression to improve link efficiency and user experience
TCP Acceleration
HTTP Acceleration (optional appliance)
Header compression for VoIP traffic
What this means to WAFA and its customers
Many satellite broadband providers see the projected 30% saving in satellite capacity as potentially 30% more profits. We at WAFA plan to invest back into the network the extra capacity gained through the implementation of DVB S2.

This means that for every 20Mbps that WAFA purchase off the satellite operator we can place 25.8 Mbps on the network at the same costs as the original DVBS platform.
This means:
Extra capacity on the network
Faster downloads & browsing
Lower contention rates on the forward channel
Much higher daily download quotas with more frequent resets

These include:
Packet shaping and traffic profiling
Enterprise caching system storing and delivering content direct from the teleport hub
Content Filtering (where required)
Intrusion detection reports to facilitate site managers to identify viruses and spyware.
Totally transparent volume reports placed on our website
The ability to purchase extra monthly volumes of data without stepping up to the next subscription package
24/7 support ticketing system
Site 7 day usage reports if required
Web located knowledge base to help in installation and troubleshooting
Tried and tested SIP VOIP solutions with online account checking
NEW!!!!
On the Star Nova S2 system, we will also provide web based reports where customers can enter their site code and review up to 20 reports on usage, traffic rates, connection etc.
Upgrades and Swapouts
As stated above, S2 technology will redefine the satellite broadband market. We would like to invite you to join the S2 revolution.
By simply swapping out your modem, you can start to reap the benefits of faster downloads, higher throughput and improved performance.
WAFA and its agents have fantastic deals on swap outs and upgrades please contact WAFA or your local agent for details.
If you have any friends on other networks or someone who is considering buying a broadband VSAT, please inform them of this new service.
