Wireless technology has become the
primarycommunications method in public
venues and commercial buildings for
both personal communication and first
responder services. As wireless penetration
rates approach and exceed 100 percent,
users demand that their wireless-connected
electronic devices work just as effectively
indoors as they do outdoors. First responders
require reliable, ubiquitous radio coverage
to ensure the safety of the public as well
as themselves in emergency situations.
CommScope’s In-Building Wireless (IBW)
Solutions provide the products and services to
address the mostcomplex mobile challenges.
CommScope’s IBW Solutions include
repeaters (or bi-directional amplifiers)
and Distributed Antenna System (DAS)
infrastructure. All of CommScope’s products
are modulation agnostic and broadband,
ensuring a future-ready solution. A DAS is
a network of spatially separated antennas
connected by coaxial cable and fiber that
provides wireless service within a building.
A DAS can be driven by a radio base
station directly or off-air using a repeater or
a combination of the two depending on the
needs of the wireless service providers (WSP)
or public safety system managers.
There are two types of DAS infrastructure:
passive and active. In a passive DAS,
coaxial cable distributes the Radio Frequency
(RF) signals from a base station or repeater.
Splitters are then used to divert a fraction of
the RF energy along the horizontal floors of
the building via coaxial cabling. An active
DAS is similar to a passive system, but uses
fiber-optics to move the signals long distances
before going into coaxial cable for the final
transmission. This type of system (often called
a hybrid-fiber-coax DAS) is broadband,
scalable and extremely flexible.
Every DAS infrastructure used in an IBW
Solution requires a signal source. WSPs play
an influential role in the DAS infrastructure
requirements to ensure the solution matches
the operator’s voice and data needs.
Working closely with the WSPs is required,
as they own the spectrum that is used by the
IBW Solutions and it makes the optimization
and operation of the system easier and
more efficient.
