Field Report: Sao Paolo’s Sistema Clube Gets Major GatesAir Upgrade

Single-frequency networks boost DTV signal strength while GatesAir liquid-cooled technology reduces tropical climate cooling loads and utility costs.

GatesAir partnered with Foccus Digital in Brazil to upgrade Sistema Clube’s over-the-air broadcast infrastructure in the greater Sao Paolo region. Using GatesAir liquid and air-cooled transmitters to power single-frequency networks, the project upgrades existing ISDB-Tb digital TV infrastructure and expands FM radio coverage. The result is improved signal quality and reliability across nearly 200 square miles.

Foccus Digital worked closely with Sistema Clube for site planning, installation and commissioning services. The broadcaster selected GatesAir transmitters based on operational efficiency benefits and what the company calls “unparalleled” leadership in single-frequency network technology and experience.

Liquid-cooled Maxiva ULXTE UHF transmitters were prominent among replacements.

Liquid-cooled Maxiva ULXTE UHF transmitters were prominent among replacements.

The TV project replaces existing transmitters with 13 Maxiva high-efficiency UHF transmitters—a mix of ULXTE liquid-cooled and UAXTE air-cooled models—which integrate GatesAir’s next-generation Maxiva XTE exciter. The exciter's advanced signal processing power and real-time adaptive correction software delivers a more robust signal to strengthen signal quality and integrity across the entire coverage area, which spans from congested urban neighborhoods to rural and coastal regions.

The FM rollout comprises two new sites powered by Flexiva FM transmitters, including the first Flexiva FLX liquid-cooled transmitter installation in Brazil.

Robert Houghtaling, business development manager for Foccus Digital said about the transmitter efficiency, "The tropical climate of the Sao Paolo region makes the reduction of air conditioning loads and energy consumption in the RF plant a high priority.  GatesAir’s liquid-cooled architecture cleanly transfers heat from inside the plant to the outside, which substantially lowers cooling and electricity costs for Sistema Clube. The modular design of all GatesAir transmitters also brings efficiency gains through simplicity of installation and ongoing maintenance, the latter of which amounts to long-term monetary savings tied to reduced labor and spare parts management.”

“The unique characteristics of single-frequency network architectures requires a careful balance of network planning and technical implementation to ensure exceptional performance. Also important is reliable synchronous delivery to multiple sites," said Bruce Swail, GatesAir CEO. The company worked closely with local partner, Foccus Digital to complete the installations. The upgrades ensure that Sistema Clube can provide an improved service using the latest technologies, while also lowering TCO across the broadcaster's entire TV and radio infrastructure.”
