GE Ensures Distributed Antenna Systems and Small-Cell Networks Stay Connected for Mobile Users at Stadiums, Campuses and High-Cell-Traffic Locations
DALLAS — Sept. 24, 2014 — Creating a first-of-its-kind solution to deliver consistent and reliable power to dozens of cellular communications nodes spread across heavily populated venues, such as a stadium or campus, GE (NYSE: GE) today introduced its new Power Express Remote Combiner. GE’s Remote Combiner and line of Power Express “Class 2¹” distribution systems improve wireless capacity and service by ensuring that even the most remote small-cellular (“small-cell”) communications node on the network receives enough power to handle peak voice and data requirements.
As part of GE’s Power Express system, the new Remote Combiner provides power to non-Class 2 loads on the network by combining up to eight discrete Class 2 power circuits to deliver reliable, bulk -48-volt DC power. This approach also ensures power circuits are not connected in parallel, conforming to National Electric Code (NEC) requirements for Class 2 power systems.
Small-Cell/Distributed Antenna System (DAS) Networks
Conventional approaches to providing wireless service are not effective at providing high-bandwidth data services in densely populated yet small venues such as office buildings, convention centers, campuses or sports facilities. By deploying a DAS or small-cell overlay in the venue, telecommunications carriers are able to expand the bandwidth capacity of the network, enhancing users’ experience on-site.
Small-cell/DAS communications nodes, which send and receive wireless signals, can be powered by low-voltage NEC Class 2 100-volt-ampere circuits. The cabling for Class 2 power circuits, similar to Class 2 data circuits for large area networks (LANs) or USB cables, can be deployed in a data-cable raceway instead of a separate electrical conduit, reducing material and installation times and costs. This means that if a hybrid/fiber power cable is deployed, power and data can be delivered in one step, speeding deployment of the high-bandwidth network. See GE’s “Toolbox of DAS and Small-Cell Power Solutions
” white paper for a more comprehensive look at these technologies.
“The challenge is that some remote nodes cannot accommodate Class 2 power because they need more power or the nodes are not configured to handle multiple, discrete Class 2 power feeds,” said Terrell Moorer, product line manager, GE’s Critical Power business. “The Power Express Remote Combiner can bundle up to eight Class 2 power circuits to deliver a reliable, bulk -48-volt DC power on any small-cell/DAS node regardless of location or power requirement.”
As part of its end-to-end solution for small-cell/DAS solutions, GE’s Critical Power business also provides a complete DC power system portfolio and AC uninterruptible power supply units with both battery backup and remote monitoring capabilities.
GE’s Critical Power business provides mission-critical applications with end-to-end power product and service solutions that maximize uptime and power efficiency. The solutions add to GE’s broader Industrial Solutions portfolio of leading technologies designed for the delivery, management and optimization of electrical power for customers across multiple industries.
