Distributed Antenna Systems (DAS)

Distributed Antenna Systems (DAS) provide a wired path for delivering mobile frequencies closer to user devices. Cabling connects macro-networks outdoors to operator RF signal sources indoors (BTS, BDA), inside a common equipment headend in the main equipment room (MER/MDF). Radio frequency signals are 'distributed' into the building core vertically over SMF/MMF fiber links that terminate at multiple remote ends on each floor (in IDF closets). Structured cabling including coaxial cabling (copper) distributes RF signals from remotes to a common antenna grid.

DAS deployments are attractive to wireless service providers that hold RF spectrum licenses across multiple frequency bands and use multiple wireless technologies (as well as wireless service providers that anticipate upgrading to new technologies such as 4G LTE and 5G).
