Satellite Operator ABE In Bolivia Completes Trial Campaign With Newtec Technology


[SatNews] Latin American satellite operator Agencia Boliviana Espacial (ABE, Bolivian Space Agency) and Newtec have successfully completed a trial campaign which transmitted more than 500 Mbps over 120 MHz on Ka-band.


The Amachuma teleport, located in the La Paz department on the western side of Bolivia at an elevation of higher than 4,000 meters above sea level.

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 2 Mbps over 1 MHz 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 1.2 meter antenna and 4W, ideal for applications, such as mobile backhaul. Meanwhile, 153 Mbps was transmitted over 36 MHz from the hub to the remote station using a 1.2 meter antenna and 4W, as well as a 9 meter, 200W hub, in a set-up typical of VSAT operators. The hub to hub (9 meters and 200W to 9 meters) test recorded a result of 257 Mbps into 60 MHz, an arrangement appropriate for IP Trunking and optical fiber restoration or back-up.

The test results, which were achieved over two months, have now been officially certified by ABE.

Newtec’s Clean Channel Technology improves satellite efficiency by up to 15 percent compared to the DVB-S2 standard. DVB-S2X boosts the satellite link up to 20 percent in DTH networks and up to 51% in other professional applications compared to DVB-S2.

Executive Comment

Iván Zambrana, General Executive Director, ABE. said, “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 CEO, Serge Van Herck, said, “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.”
