Single-frequency network projects boost DTV signal strength and extends coverage of FM signal, while GatesAir liquid-cooled technology reduces cooling loads and utility costs
GatesAir, a global leader in wireless, over-the-air content delivery solutions for TV and radio broadcasters, has 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 coverage, improving signal quality and integrity across nearly 200 square miles.
Foccus Digital, which worked closely with Sistema Clube across all site planning, installation and commissioning services, opted for GatesAir for operational efficiency benefits and what the company calls “unparalleled” leadership in single-frequency network technology and experience.
The FM rollout comprises two new sites powered by Flexiva™ FM transmitters, including the first installation of a Flexiva FLX liquid-cooled transmitter in Brazil; and one Flexiva FAX air-cooled transmitter. GatesAir Intraplex® SynchroCast® technology seamlessly networks FM content across multiple transmission sites over IP, ensuring all transmitters deliver program content to their specific coverage areas in lockstep.
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 XTE’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.
Robert Houghtaling, business development manager for Foccus Digital, emphasizes that the efficiency gains afforded through GatesAir liquid-cooled technology for TV and radio have been especially impressive.
“The tropical climate of the Sao Paolo region means makes the reduction of air conditioning loads and energy consumption in the RF plant a high priority,” he said. “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.”
Specific to maintenance, Maxiva and Flexiva transmitters adopt a similar modular architecture that allows engineers to easily replace power amplifier modules and power supplies while remaining on the air. The streamlined interior design of these transmitters—based on GatesAir’s PowerSmart® Plus green transmitter architecture with broadband amplification—also means that engineers can share a minimal, common spare parts inventory across all transmitters on the network.
“The unique characteristics of single-frequency network architectures requires a careful balance of network planning and technical implementation to ensure exceptional performance across multiple sites tied to signal integrity and synchronous delivery,” said Bruce Swail, CEO, Gates Air. “Working closely with our Brazilian partner Foccus Digital, these upgrades ensure that Sistema Clube has the latest available technologies to at once improve quality and coverage for local audiences while lowering total cost of ownership across their TV and radio infrastructure.”
