A new strategic white paper from Alcatel-Lucent points out that "there is no one-size-fits-all solution to the indoor [wireless] deployment challenge," and that [currently] "available Distributed Antenna System (DAS), Distributed Radio System (DRS) and small cell architectures each have strengths and weaknesses, which must be assessed and balanced against network objectives, the limitations of the indoor environment, future capacity requirements, and cost."
The paper provides an explanation of the basic in-building architectures that are available to wireless operators, and assesses the strengths and weaknesses of each.
