en.Wedoany.com Reported - Liberty Costa Rica and Ericsson are deploying a 5G network using Ericsson's latest Radio System portfolio, based on next-generation radio access network equipment, designed to enhance performance while reducing energy consumption and carbon dioxide emissions for more sustainable operations.

Liberty's deployment of the Ericsson Radio System portfolio includes three core devices: the AIR 3255 Massive MIMO radio unit in the 3.5GHz band, an ultra-light and highly sustainable unit that reduces energy consumption by approximately 30% and embodied carbon emissions by 20% compared to previous generations; the Radio 4432 B28 in the 700MHz band, optimized for high efficiency and wide coverage, suitable for extending 5G to rural and hard-to-reach areas; and the RAN Processor 6655, a next-generation baseband processor with enhanced AI capabilities, higher capacity, and energy efficiency, integrating more network functions into fewer hardware components to reduce site-level energy consumption.

These solutions are driven by Ericsson Silicon system-on-chips (SoCs) and advanced features such as Massive MIMO, beamforming, and dynamic shutdown, which direct radio power only to active users and automatically adjust energy consumption in real time, reducing energy waste. Ericsson adopts a lifecycle perspective when addressing embodied carbon emissions, focusing on the entire value chain from manufacturing and transportation to installation, reducing overall carbon emissions through measures such as minimizing material usage, increasing technology integration, optimizing logistics, and extending product lifespan via software upgrades.

According to Ericsson's latest Sustainability Statement, the company achieved its target six months ahead of schedule: by the end of 2025, the average energy consumption of new typical radio base station sites was reduced by 40% compared to the 2021 baseline. Ericsson is now moving toward a new goal of reducing both energy consumption and embodied carbon emissions of new radio base station sites by 50% compared to 2021 levels by 2027.

The deployment of Liberty Costa Rica's 5G network also supports its own climate strategy, which aims to reduce Scope 1 and Scope 2 emissions by 30% compared to 2021 by 2027, while decreasing Scope 3 emission intensity per million colones of added value by 39%.

Wendy Madriz, Liberty's Communications Manager, stated that the 5G network the company is building for Costa Rica delivers faster speeds and greater capacity while being implemented more efficiently and environmentally friendly. She emphasized that Liberty is committed to connecting communities while protecting the environment.

Sean Cryan, Head of Ericsson's Customer Unit for Latin America North and the Caribbean, noted that this 5G deployment demonstrates the measurable role the telecommunications industry can play in transitioning to a more sustainable future, and expressed hope to expand this impact across a wider range in Latin America.
