GatesAir, along with Sonotec, has transitioned private broadcaster ATB Bolivia to ISDB-Tb digital television, in the cities of Cochabamba and La Paz. GatesAir supplied its Maxiva ULXTE liquid-cooled transmitters to support the transition, which enabled Sonotec to install and commission both systems in advance of the June deadline.
The DTV systems transmit one ISDB-Tb HD channel and one mobile channel to populations within and near the city limits, with satellite relay to TV service providers in rural areas. ATB anticipates that a third DTV channel will be added to the network shortly, noting that the ULXTE’s bandwidth will help to maximize ISDB-Tb spectrum.
“Cochabamba and La Paz sites were challenging as we needed new transmitters that could work with the existing RF infrastructure. The size and modularity of these transmitters simplified the installation logistics, which was important due to the timeline for this phase of the DTV transition,” said Javier Fernandez, CTO, ATB. The design lowers air conditioning usage, reducing overall energy consumption. To ensure a smooth installation and commissioning process, regional GatesAir sales engineers held local training seminars, followed by on-site visits.
“The performance of our Maxiva transmitters and ULXTE liquid-cooled architecture will reap benefits for ATB Bolivia for years to come, at once reducing labour and expenses for both organisations, while also enabling new DTV services for the Bolivian population,” said Rich Redmond, president and MD – International, GatesAir.
