3. Introduction
Our 10dBm~15dBm Booster is the perfect solution for providing a wireless improvement in the cellular reception
of a home, office, restaurant, VIP Room, apartment, building or shopping mall, in the quickest time possibly. One
Booster covers 300 to 3000 square meters.
This Booster has Manual Gain Control (MGC) feature that enables engineers to reduce the gain of the Booster
manually if oscillation is detected or too strong input power level during installation, which will help to get the
best coverage effect without any interference back to mobile network.
And in order to maintain safe and specific output signal levels, this Booster has built-in signal oscillation
detection circuit to adjust the gain automatically so as to avoid interference to the cellular network, also it gets
color changing LED’s indicating its environmental status: the Alarm LED’s located on the front of the unit will
change color from green to orange or red, (depending on the input power level) if the system detects signal
oscillation in either band or, if the input signal is beyond a safe limit.
Our Boosters also feature a Network Safe / MUTE feature that automatically shuts off the Booster to protect the
cellular network if no adjustments are made to eliminate alarm readings on the Booster’s LED’s. You will want to
make sure the LED’s remain green at all times for optimum system performance. (This function is not available
for some specific models for which we will specify when you purchase)
Below diagram shows how simple and fast 10dBm~15dBm Booster system is installed and works effectively
One Yagi antenna, as donor antenna, is installed at the top of the roof to pick up good mobile signals from
outside, and send through 5D-FB cable to 10dBm~15dBm Booster to amplify the signals significantly, then the
output signals are divided into two signals by 2way splitter, sent to two indoor omni antennas and finally
transmitted into area. Very clear phone call or high speed mobile data are immediately achieved within the area.
