A Digital DAS converts each carrier’s signal to zeros and ones before combining them and transmitting over fiber optic or ethernet cable. This conversion and combination process is computationally expensive, which makes digital DAS systems considerably more expensive than their analog counterparts.
One of the biggest benefits of deploying a Digital DAS is that they are much less susceptible to interference, and thus more performant. A second benefit is that Digital DAS platforms allow the capacity of the signal sources to be directed to different areas of a venue. This is particularly important when the capacity of a building shifts dynamically – think for example of a large cafeteria or event space on a school, university, or office space.
If both the signal source and Digital DAS platform support the “Common Public Radio Interface” (CPRI) specification, it’s possible for a signal source’s Baseband Unit (BBU) to communicate directly with the DAS master unit and through to the remote units without any conversion to an analog RF signal.
DAS systems are widely used in offices, suburbs, stadiums, & other venues where the coverage or network capacity of a specific service provider is required to be enhanced.
Genesis Technology Services provide full end-to-end survey, design, build & maintenance of DAS systems for its customers.
