Small Cells, DAS & Het-Nets

AC/DC Power Solutions: The Forgotten Small Cell Requirement

The demand for high quality data services on LTE networks continues to grow as mobile subscribers increasingly use their smartphones and tablets to watch mobile video, stream audio and update social media sites. As this usage increases, mobile operators are evolving their radio access network (RAN) to augment the coverage and capacity of their networks. These dense heterogeneous networks (het-nets) include many types of small cells – indoor small cells (picocells), Wi-Fi, outdoor small cells (metrocells and microcells), Distributed Antenna Systems (DAS), and Remote Radio Heads (RRHs).

Mobile operators must consider many factors when determining the location of the small cells in their het-net. As part of these considerations, the mobile operator must ensure that a steady power source is available and must answer several questions regarding power. Does the small cell require AC or DC power? How much power is required? What power is available at the site? Will backup power be required?

This market study provides an analysis of the power requirements of various small cells, details the types of power systems that are available, and discusses the issues considered when choosing a power source.
