DAS Part Two: Where Did DAS Come From?

Part Two of Minuteman’s Series: All About DAS

DAS ThumbnailIn February, we began a series of blog posts that explores distributed antenna systems (DAS) in-depth, relating how Minuteman plays a role in the growing marketplace.  In our first post, Samantha discussed the basics of DAS, explaining it as a network of antennas strategically placed and connected to a common source that allows for better wireless service across geographical areas and larger buildings, such as stadiums, hospitals, and campuses.  So how did DAS emerge in the Telecom industry?  Today we are going to dive into the origin of DAS and how it has grown into an increasingly common way to deal with isolated spots of poor coverage.

 What Did People Use Before DAS?

While they both allowed two-may mobile communication, tunnel transmitters and leaky feeders have a number of deficiencies, including a limited range and a limited line of sight, coupled with their transmission’s inability to pass through solid objects like rock.

From Niche to Necessity: Why DAS is Important

But due to skyrocketing mobile data demands, operators have turned to DAS as a much-needed boost to the added capacity and requirement for better, more consistent signal coverage.

DAS and Minuteman

Boosted wireless connection is essential in today’s digital commotion.  But if those systems go down, the connection goes down as well. Thus, as with any system that employs utility power, DAS needs power protection.  Minuteman’s line of UPS systems provide DAS antennas with backup power and protection for everything from blackouts and brownouts,to surges and spikes.
