The Shadowing Effect of Femtocells
What are Femtocells?
By Definition: A Femtocell is the smallest as well as a minimum
type of cell which is used to enlarge cellular network connectivity within a
targeted geographical area (typically a small, undersized, single location).
Femtocells are used as a wireless access point
that improves cellular reception inside home data traffic or office building.
This device communicates with the mobile phone and converts your voice calls
into voice over IP (VoIP) packets. The packets are then transmitted over a
broadband connection to the mobile operator's servers.
While it is the smallest although smartest in the family of
small cell technologies, Femtocells uses the smallest quantity of power; as
such, they don’t offer as much of an impact when attempting to expand network
connectivity. Matter of a fact is that, by differentiating other varieties of small
cells, such as picocells and microcells; femtocell presents the slightest
amount of additional bandwidth, so that it could be only deployed in specific circumstances.
Note: Femtocells are compatible with
CDMA2000, WiMAX or UMTS mobile telephony technologies, using the provider's own
licensed spectrum to operate. Typically, consumer-based femtocells will support
only four active users, while enterprise-grade femtocells can support up to 16
active users.

The Shadowing Effect
Even though Femtocell network range and capacity are relatively limited, it’s their low powered nature that often makes them the small cell geographic choice. Before deployment of a small cell network begins, the targeted space must be analyzed for certain limiting factors that might cause interference to the network signals, and the result of the analysis often provide restrictions for the use of larger small cell technologies due to the probable signal interference.
Firstly of all, for all small cell
systems, there is a “shadowing effect” with the signal that must be taken into
consideration when designing the small cell network. For some small cells, such
as microcells, the broadcasted signal is strong enough that if placed too close
to another transmitting microcell, the two signals can interfere with one
another and cause signal degradation.
This
shadowing effect can cause serious problems for the targeted location if it
just so happens to be filled with signal interfering obstacles. For example,
let’s say your office space is arranged in such a manner that there is a
combination of cubicles and smaller enclosed spaces used for meetings. These
areas are separated by glass, concrete, and other building materials that can
disrupt the traveling signal of the microcell.
But what’s even bad, is that
sometimes adding extra microcells to the office will only cause the signals to corrupt
further, but here’s where Femtocells truly outclass others. Because of its tiny
footprints, Femtocell designs allows for the placement of multiple antennas
around the space, providing the necessary network connectivity without distracting
the Femtocell network signal and simultaneously negating the effects of
interfering obstacles.
In
this situation, Femtocells can be tactically positioned close to and around the
workspaces, as well as each indoor meeting room in order to provide a steady
cellular connectivity, and avoiding the shadowing effect.
For Future Generations
For
smaller locations, or locations that attribute many signal blockages, Femtocell
technology will maintain the popularity to be a stable network solution. The low
budget, low power-driven nature makes them a smart alternative even to the
larger, and costlier small cell solutions, especially when the need for network
connectivity only covers a few individual users at any given time.
However
for casual customer at home, the future of Femtocells is quite lacking
confidence. Even though Femtocell networks are undersized, low power-driven,
and easy to deploy, cellular providers are fluently taking up the facility by
offering Wi-Fi calling, which directly competes with Femtocell potentiality.
Also, as popular messaging applications move more users away from traditional
SMS text messaging, the need for a reliable cellular connection in the home is
likely to continue to decrease in priority.
