Expanding Cell Coverage with DAS

The proliferation of smart devices in high-density urban areas like high-rises, sports arenas and university campuses is creating challenges to provide coverage to all users.

To expand wireless coverage and reduce infrastructure costs, Mobile Network Operators (MNO) are working with Neutral Host providers and facility owners to deploy Heterogeneous Networks (HetNet) that include Femto cells, Pico cells, Metro cells and Distributed Antenna Systems (DAS).  “Black holes” and “Not Spots” inside buildings and outside of cell tower coverage areas can be served with these small cells and DAS.

Neutral Host operators can establish a DAS head end at a central location in the campus for connectivity to multiple MNOs, or deploy multiple head ends in each DAS location.  The wireless services are distributed from the DAS head end to different indoor and outdoor DAS locations.

The slideshow below illustrates how indoor and outdoor DAS can supplement cell tower coverage in a university campus.
