Latin American satellite operator Agencia Boliviana Espacial
(ABE, Bolivian Space Agency) and Newtec, a specialist in
designing, developing and manufacturing equipment and
technologies for satellite communications, today announced the
successful completion of a trial campaign – which transmitted
more than 500Mbps over 120MHz on Ka-band.
The Ka-band tests demonstrated three main use-case scenarios,
showing the versatility of Newtec’s MDM6000 series, which as
well as being capable to transmit up to 425Mbps
bi-directionally, can also operate at much lower rates as
required for multicarrier applications. The modems also support
different standards, including DVB-S2X, and feature Newtec’s
Clean Channel Technology®.
Major results include transmitting 2Mbps over 1MHz bandwidth
from the remote to the hub station in Amachuma (located in the
La Paz department on the western side of Bolivia at an elevation
of higher than 4,000m above sea level) using a 1.2m antenna and
4W, ideal for applications like mobile backhaul. Meanwhile,
153Mbps was transmitted over 36MHz from the hub to the remote
station using a 1.2m antenna and 4W, as well as a 9m, 200W hub,
in a set-up typical of VSAT operators. The hub to hub (9m and
200W to 9m) test recorded a result of 257Mbps into 60MHz, an
arrangement appropriate for IP Trunking and optical fiber
restoration or back-up.
“The tests with Newtec demonstrated the outstanding
performance of the company’s equipment for a variety of
applications, and the high quality of our satellite services”
said Iván Zambrana, General Executive Director of ABE. “The
testing was conducted successfully and showed support for
different standards (including DVB-S, DVB-S2 and DVB-S2X) and
higher spectral efficiency levels with modulation schemes from
QPSK to 256APSK. Advanced coding and bandwidth optimization was
also achieved through reduced roll-off factors and Newtec’s
Clean Channel Technology.”
Newtec’s Clean Channel Technology improves satellite
efficiency by up to 15% compared to the DVB-S2 standard. DVB-S2X
boosts the satellite link up to 20% in Direct-To-Home (DTH)
networks and up to 51% in other professional applications
compared to DVB-S2.
Newtec’s CEO Serge Van Herck added: “The results of these
tests are very relevant for the Latin American market and
demonstrate that our equipment is suitable for use by the
majority of applications in the Satcom market, delivering not
only the highest efficiency but also future-proof technology and
reliable solutions.”
The test results, which were achieved over two months, have
now been officially certified by ABE.
