-Callboost use Chinese the topest secret technology on mobile phone signal booster.
-Callboost mobile phone signal boosters have excellent appearance and the most advanced technology material.
-Callboost C20L single band use the newest LCD display.You can see the actual operating parameter.
-Each one motherboard use the topest technology so that Amplitec signal boosters have ALC,MGC and Auto turn-off function.
Auto turn-off in case of excessive self oscillation or over input,and ALC function,auto control of output power for stable coverage.
-Self oscillation elimination, auto degrading of output power in case of insufficient isolation detected.
-Real time isolation check and alarm.
-85dB 33dBm big power easy to cover over 1000-3000m2 indoor building.
-Production function description
a) Manual gain control (MGC)
-When installing and operating the repeater ,engineer can adjust uplink and downlink gain in the range 1-31dB to ensure the repeater work in full output power condition.
b) Automatic gain level control
-When the downlink received signal+ downlink gain exceeds 20 dBm, the repeater will automatically activates the ALC function to reduce the downlink gain and keep the downlink output power of the repeater within 20dBm.
-When the uplink received the moble phone signal +uplink gain exceeds 20dBm,the repeater automatically activates the ALC function to reduce the uplink gain and keep the uplink output power of repeater within 20dBm.
c) Automatic balance of uplink and downlink gain
-When the downlink signal is strengthened during the operation of the repeater and the ALC starts to attenuate the downlink gain, the system simultaneously attenuates the uplink gain to maintain the signal balance between the downlink and uplink.
d)Isolation detection and elimination self-excitation
-The repeater system detects the isolation between the BTS port and the MS port in real time. When the isolation is less than +15dB of the system gain, the system will automatically reduce the gain to prevent the system from self-excitation.
e) Automatic shutdown
-When the repeater system exceeds the gain attenuation range of the system due to too strong received signal level or too low for isolation, the repeater system automatically shuts down the output to prevent the repeater from being burnt because of overload.
f) Uplink idle turn-off
-When there is no end users in the coverage area, the system will automatically turns off the uplink output to minimize interference of the radio wave in the space.
-Callboost CB85B signal booster can solve many signal problems easily.
-Callboost 2g 3g 4g signal booster cover your home signal without blind area easily.Our mobile phone signal boosters all have one year warranty.
