As the leader in distributed antenna systems (DAS), CommScope has visibility into what’s
going on in all areas of the wireless RF path, especially indoors. Sharing our
view on in-building wireless is what we try to accomplish in the “Wrestling with the Data Tsunami Indoors” infographic that I blogged about recently. That infographic generated some interest from RCR
Wireless, who recorded a 20-minute video interview with me where we dug
a little deeper into the details.
CommScope’s experience in the field confirms two points
made by RCR’s Martha DeGrasse in her recent DAS article:
- There is increased demand for DAS and other “small cell” solutions
- There is a lack of RF engineers who know how to deploy them
I touch on these points in the RCR video as well as broader
trends and drivers.
When discussing in-building wireless solutions, we must
consider three important numbers--1.5, 30 billion and 2. The rate of wireless
data consumption doubles about every 1.5 years. That’s the data tsunami.
Additionally there are 30 billion square meters of commercial real estate
globally. But only about two percent of it has a dedicated in-building wireless
solution for licensed spectrum.
As a former RF engineer, those three numbers stand out as a
huge opportunity for placing sites to densify the cellular network; however, we
must consider who is managing technology and communications inside commercial
buildings. That would be IT professionals. The RF installers typically handled
the outdoor macro network. There is a subgroup that specializes in DAS, but
there is not enough of them to support the full data tsunami indoors. That’s
why solutions that simplify design, installation and maintenance for
in-building wireless systems need to be tailored to the realities of who will
be doing the work.
Check out Martha’s article and my video for more details. What do you think? Is the industry lacking in RF
engineers? When it comes to deploying in-building wireless systems in
enterprises, how do we solve this issue?
