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