Radio Frequency Systems (RFS), a global designer and manufacturer of cable, antenna and tower systems providing total-package solutions for wireless and broadcast infrastructure, today announced the availability of its new lithium-ion battery solution using NMC technology. The batteries can be used at RAN/C-RAN sites to ensure RRH operation and network availability during power grid outages; at independent, self-sustaining sites sourced by renewable energies; and for powering of temporary sites without connectivity to a power grid or fuel generators.

The modular RFS battery solution includes battery cells, a charging circuit, algorithm, and software for remote access. It can be used in many different scenarios requiring stable performance in high working temperatures –for example, an un-air-conditioned outdoor cabinet– and remote monitoring management.

RFS’ compact, eco-friendly Li-ion batteries reduce volume by up to 50% and installation weight by 20% over traditional acid batteries, while increasing capacity and eliminating the need for additional cooling to maintain operational temperatures.

"This evolution from acid to Li-ion batteries supports CAPEX and OPEX savings in RAN and C-RAN network deployments by reducing space requirements and rent cost, lowering energy consumption and carbon footprint, and improving safety and monitoring management," said Dietmar Brunsch, chief engineer / product manager ISR, RFS. "The addition of the new battery supports our broader global strategy to provide a comprehensive product portfolio – including CPRI panels, power cables, fiber jumpers, DC wires and more – that meet all of our mobile network customers’ needs."

The easy-to-install batteries are designed for a 19 inch rack and feature a Battery Management System (BMS) for remote access to battery parameters and hot plugging functionality, allowing for upgrades without requiring shutting down the site.
