The Pentatranspack Solution

The current investment in VSAT networks is based on the DVB-S transmission standard that is now facing obsolescence. The new-generation DVB-S2 technology delivers significantly enhanced network efficiency, with about a 30% savings from improved satellite space segment utilization.   Rather than replacing the VSAT itself, a simple and cost-effective upgrade can solve the DVB-S2 compliance requirement.  The new pentatranspack trans-modulation solution from PentaStream enables a smooth, quick, economical migration path to improve existing VSAT assets.

Minimal logistic efforts are required to implement the PENTATRANSPACK upgrade, and the quick ROI payback is estimated at 5-7 months.  

The PentaStream PENTATRANSPACK is a unique trans-modulation device designed as a practical and trouble-free way to migrate existing VSAT networks to DVB-S2.  The PENTATRANSPACK is an indoor unit simply installed by the end user between the LNB and the VSAT. 

The PENTATRANSPACK operates as a transparent and integral upgrade to the network. The PENTATRANSPACK makes it simple and cost effective to migrate to the more efficient DVB-S2 standard, thus leveraging the current investment in the VSAT network.

Why DVB-S2 ?

DVB-S2 is the second-generation standard for satellite broadcasting, which is now widely adopted. The new specification benefits from recent developments in channel coding (LDPC codes) combined with a variety of modulation formats (QPSK, 8PSK, 16APSK and 32APSK). This more efficient technology yields  increased transmission capacity along with an approximately 30% improvement in space segment utilization.
