Large service providers as well as venue owners (for example, stadiums, casinos, and malls) have been using distributed antenna systems (DAS) for the past two decades to improve network coverage in venues where the traditional macrocell approach does not work.
As mobile networks migrate from 2G to 3G and 3G to LTE, DAS architectures have evolved from passive to active, in which repeaters are replaced with low-power remote radio heads connected through fiber optic cable to the DAS hub, resembling today’s C-RAN macro architectures.
This white paper discusses one of the key components of HetNets namely active DAS and the challenges, opportunities, and the streamlined deployment process for DAS.
