GE sol'n powers high-volume small cell networks

GE has developed what it says is 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. The Power Express Remote Combiner and line of Power Express "Class 21" distribution systems improve wireless capacity and service by ensuring that even the most remote small-cell communications node on the network receives enough power to handle peak voice and data requirements, the company stated.

As part of GE's Power Express system, the Remote Combiner claims to provide power to non-Class 2 loads on the network by combining up to eight discrete Class 2 power circuits to deliver reliable, bulk -48VDC power. This approach also ensures power circuits are not connected in parallel, conforming to National Electric Code (NEC) requirements for Class 2 power systems.

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 centres, 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 100V-A 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/fibre power cable is deployed, power and data can be delivered in one step, speeding deployment of the high-bandwidth network.

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.
