The DVB-S2/SCPC (DVB-S2 SCPC) is an excellent technology for satellite Internet connection with 100% guaranteed bandwidth
The provision of a satellite internet has existed for many years. The new standard, DVB-S2, provides opportunities to improve the performance of IP networks via satellite.
Advanced error correction receiving IP packets functions are available on the DVB-S2 SCPC, thereby increasing the available bandwidth.
Thus, a conventional transponder can now offer higher bandwidth 130Mbps IN DVB-S2 SCPC against 40Mbps before.
The forms of modulation become more sophisticated with the DVB-S2. The support of VCM and ACM give us the tools to optimize the use of space segment
> VCM optimizes internet via C-band satellite by assigning different FEC different VSAT based on their position on the coverage area of the satellite
> ACM optimizes internet via Ku-band satellite dynamically defining MODCO VSAT
> IP encapsulation in MPEG-TS has been optimized by the introduction of Generic Streams brings increased efficiency when used on Internet connections, satellite DVB-S2
DVB-S2/SCPC means that the technology used in the reception of DVB-S2 and the technology used in the show is SCPC bandwidth of this type of service is 100% guaranteed.
The +
> price lower bandwidth SCPC / SCPC traditional
> excellent performance of the reception thanks to the many improvements made by the DVB-S2
> greater link availability Ku-band in the rain through the ACM (Adaptive Coding Modulation) present in the DVB-S2
The -
> only available bandwidth 100% guarantee and therefore fairly upscale
> the price of modems can be significant enough in terms of their performance even if we offer all in one modems in some of our services
> latency Internet satellite link DVB-S2/SCPC is less stable than a SCPC / SCPC link as optimizations can vary latency
In conclusion, the Internet services via DVB-S2 SCPC (DVB-S2/SCPC) satellite are perfect for a client who wishes to have a 100% bandwidth guarantee whose principal use is the Web, email and file transfers.
VoIP will work well with the implementation of QoS rules, but it is recommended to take a DVB-S2/SCPC link if the use is 100% VoIP for the use of certain boxes compression is tricky. Highly sensitive to latency transactional applications work better with SCPC / SCPC link even if they work well with DVB-S2/SCPC link.
Links running DVB-S2/SCPC (DVB-S2 SCPC) are more and more replacing SCPC / SCPC links as they offer the best quality / price ratio for Internet connections via satellite bandwidth 100% guaranteed.
