DC Small Cell Power Systems

With an inconspicuous profile and small footprint, DongAh Elecomm’s Cheshire™ Series power systems are perfect for DAS and small cell 4G/LTE wireless/telecom base stations where aesthetics are important­. Cheshire™ systems are designed to withstand all types of weather conditions and harsh environments for reliable power anywhere on the planet. With more than 300,000 deployed, their proven reliability gets attention.

Our Cheshire™ Series of power supplies is designed to support expansive growth in small cell 4G/LTE wireless/telecom base stations and network equipment. Small cells (pico cells, femto cells, micro cells, carrier wi-fi, etc.) are primarily added to increase capacity in hot spots with high user demand and to fill in areas not covered by the macro network – both outdoors and indoors. They also improve network performance and service quality by offloading from the large macro-cells. End users benefit from more reliable data connections and higher data throughput. Mobile broadband connections are growing at a rate faster than the Earth’s population, with industry experts predicting 1000x growth in traffic volumes by the end of 2020.
