Glossary of Terms
Attenuation: the reduction of the RF signal usually measured in dB. Attenuation is the opposite
of Gain. Increasing attenuation has the same effect as turning down the volume control of a
radio or stereo speaker.
Booster: also known as: RF amplifier, repeater or signal enhancer.
dB: short form for decibel. Unit of measure for RF signal gain or attenuation.
Directional antenna: an antenna designed to focus its energy mostly in one direction.
Distribution antenna: internal antenna used to distribute signal to the interior of a
building or structure.
Donor Antenna: outside antenna used to provide signal from outside to inside.
Frequency band: the operational frequency range of the Smoothalker booster and the cellular
network frequencies that are amplified. These are commonly referred to as the ‘Cellular Band’
(824-894 Mhz) and the ‘PCS Band’ (1850-1990 Mhz).
Gain: the increase of the RF signal usually measured in dB. Gain is the opposite of
Attenuation. Increasing gain has the same effect as turning up the volume control of a radio or
stereo speaker.
LED: Light Emitting Diode.
Omni-directional antenna: an antenna designed to radiate its energy equally in all
directions.
Oscillation: term to describe a feedback loop. This occurs when the signal from one
antenna reaches the other antenna and the booster amplifies the signal creating a loop. This is
the same effect as the squeal one hears when a speaker is brought close to a microphone.
RF: Radio Frequency.
RX: ‘receive signal’ originating at a base station or tower.
Splitter/Power Divider: a component with input and output connectors that will allow one
originating signal to be split and distributed to two or more antennas.
TX: ‘transmit signal’ originating from a cellular phone or data device.

FCC Part: §15.21 Information to Users
Warranty
Smoothtalker boosters are warranted against manufacturing defects for a period of one year from the date of purchase.
The original bill of sale is required for any warranty claims.
For warranty claim contact original dealer or smoothtalker.com
“The users manual or instruction manual for an intentional or unintentional radiator shall
caution the user that changes or modifications not expressly approved by the party
responsible for compliance could void the user’s authority to operate the equipment.
In cases where the manual is provided only in a form other than paper, such as on a
computer disk or over the Internet, the information required by this section may be
included in the manual in that alternative form, provided the user can reasonably be
expected to have the capability to access information in that form.”
“This device complies with part 15 of the FCC Rules.
Operation is subject to the following two conditions:
(1) This device may not cause harmful interference, and
(2) this device must accept any interference received, including
interference that may cause undesired operation.”
RF Expousure Warning
This device shoudl be installed with the antenna supplied. The atenna shall be mounted at a suitable location
which is a minimym 16in (40cm) away from the user or nearby persons in order to comply with FCC rules
conscerning MPE safety limits.
