Flexible, Modular and Universal Power Conversion for Small Cell Stations in Distributed Systems

Inhalt:
This article lays out power system architecture for Small Cell and Distributed Antenna Systems applications. The exponential increase in mobile data traffic forces the mobile telecom infrastructure to be distributed within diverse coverage areas ranging from heavily urbanized environments to rural settings. At the same time, high level of availability that is provided by classic landlines is expected from the mobile network, which in turns raise the question of how reliable and resilient is the power system that supplies energy to a large number of small, distributed base-stations. Guidelines and benefit analysis of a modular, power component based, distribution and conversion approach are introduced along with implementation results.
