Overview

C15F-5B wide band mini Booster is designed with harmonious humanity conception, as a perfect

combination of environmental protection and signal coverage. The C15F-5B products carried with

many features like, low consumption, light weight, high gain, low output power and easy

installation, etc, It provides a rapid and perfect solution to solve and optimize the weak signal of

houses, offices, hotels, elevators, underground parking lots and other small weak signal area.

On the condition that to assure the normal communication, C15F-5B products using the smallest

Rx and Tx power to achieve the link balance among BTS and mobile phone and Boosters,

guaranteed that the least Rx and Tx power from the products, the least harm to environmental

pollution and human body's radiation.

C15F-5B products has ALC function, which offer the product reliability and the coverage stable

signal technically. In addition, the C15F-5B products adds ALC warning directive function to let

users knowing signal quality by the indicator's color.



The system has the automatic gain control function. By comparing the voltage value of the

UL detection tube and the line detection tube with the set value, if the sampling value is

larger than the set value, then increase the attenuation value of the corresponding channel

attenuator until the corresponding detection tube voltage is less than the set value. If the

sampling value is less than the set value, then decrease the attenuation value of the

corresponding channel attenuator until the corresponding detection tube voltage is larger than

the set value or the attenuation value is 0.

The system has the output over power cut off function. When the attenuation value of the UL

or DL attenuator caused by the AGC control is more than or equal to 31dB, the system will

switch off the corresponding channel. Otherwise, when the attenuation value is less than

31dB, turn on the corresponding channel switch.

The system has self-excited detection function. When its UL or DL occurs self-excitation, the

system shuts down the switch and keep 120 seconds, the number of self-excited statistics plus

1. After 120 seconds, turn on the switch of UL and DL, if continue to detect the self-excited

then turn off the switch and keep 120s, the number of self-excited statistics plus 1. If there is

no self-excited, the self-excited statistics are cleared and the system return to normal. If the

self-excited is detected up to 3 times is succession, the switch will be permanently turned off

until the power off and restarted. Any detection results in no self-excited before the

permanent shut-off, the umber of self - excitation statistics will be cleared, and the system

will return to normal.



Booster is a linear amplification of the wireless signal. When the Booster is not installed right

and lead to self-excited situation, the Booster by detecting the linear relationship between

input and output to determine self-excited, if self-excitation it will turn off their own to

prevent Network with itself until troubleshooting.



Inside the detection area of Boosters, if the UL does not occur calls or data exchange in a

long time (about 5 minutes), it will judge this area do not need Booster. At the same time,

Booster will shut down the UL automatically and sleep until it detects its UL activity and
