Signal Booster Description:
You are probably wondering what a cell phone signal booster
actually is. This is a common reaction that people have, and we are
taking a moment to explain it to you. In the current age of mobile
technologies, where the personal devices are wireless and private,
every device is backed by a “backbone” wireless network carrier,
which could be one of the many major carriers in the country, such
as Vodafone. Over the years, the carriers have developed their
infrastructure well and have been able to cover most of the
country. But there are large parts of the country where the signal
coverage is weak or reaches sparingly. This is where the cell phone
repeater comes into play. They resolve calls data and LTE reception
mainly. In terminology, we call correspondingly 2G 3G and 4G
signal.
A cell phone booster is a device that gathers the signal
from the air, usually through an outdoor unit (such as an antenna),
and “conveys” this signal to an indoor unit that is supposed to
boost the signal. This conveying is done through a wired connection
between the outdoor antenna and the indoor unit. The indoor cell
phone booster, in turn, is provided with external power through a
power outlet and has a complex circuitry that allows it to amplify
the weak signal that has been received by the outdoor antenna. The
indoor unit then sends the electrical signal to the indoor antenna
that is directly connected to the unit, and the antenna converts
the electrical signal to waves of the same frequency as were
received by the outdoor unit. This, the frequency range of the
waves does not change, and the cell phones do not notice any
difference, except for a dramatic increase in the signal power that
they are receiving.
Thus, as we can see, cell phone signal boosters are devices
that literally boost the cell phone signal that you are receiving.
This is done through some complex circuitry that works through the
use of external power and boosts the signal to usable levels.
