A 5G macro cell using massive MIMO technology and operating as an edge compute site may require up to twice as much power as a 4G site.
While power requirements increase, the corresponding power per bit is lowered due to the tremendous processing power of the 5G site. To meet these processing needs, upgrading the macro cell power infrastructure requires the deployment of more power conversion equipment and energy storage. New powering techniques are also required—power needed at the top of the antenna may originate at the base and be carried via cabling to the top. Similarly, remote radio heads distributed outwardly from the cell site may be powered from the base station using some form of remote power delivery.
EnerSys® is a full-service provider for macro cell upgrades. Our Alpha® DC rectifier systems are compact, high efficiency units with expanded distribution positions for simultaneously powering multiple devices at the site. The power system is managed by an intelligent controller that enables smart site management, monitoring and alarming.
Our Purcell Systems® site support cabinets provide space for radio equipment and power, while battery support cabinets provide additional battery reserve capacity. These GR-487 compliant cabinets feature cutting-edge thermal management systems providing 6000W user thermal capacity.
Our broad suite of batteries includes Valve Regulated Lead Acid (VRLA) and advanced technologies. An ideal solution for macro cell applications is our PowerSafe® SBS XL batteries which use Thin Plate Pure Lead (TPPL) technology for longer life at elevated temperatures.
To complete the process, our services range from site planning and engineering to installation and commissioning. Once the site is turned up, we offer after-market services such as facility management and preventative maintenance.
Our combination of cabinets, power conversion and batteries uniquely positions us to provide solutions that can be tailored to our customers' needs.Nick Durgan, EnerSys Senior Product Manager
