-Why Choose The Best Brand Callboost Signal Booster Manufacturer Of The World?
-Callboost use Chinese the topest technology on mobile cell phone signal booster repeater to increase cellphone signal received,boost signal strength.
-High power design so that easy to cover indoor coverage area upto 6000-8000㎡,outdoor upto 3-6km.
-Each one motherboard use the topest technology so that Callboost 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.
-Device auto detect isolation after start-up,to avoid self-oscillation.
-Able to increase signal coverage,decrease mobile phone radiation,and increase mobile phone battery lifespan.
-Digital filter technology makes out-of-band rejection more effective.
-Production function description
a) Manual gain control
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 37 dBm, the repeater will automatically activates the ALC function to reduce the downlink gain and keep the downlink output power of the repeater within 37 dBm.
When the uplink received the moble phone signal + uplink gain exceeds 40 dBm,the repeater automatically activates the ALC function to reduce the uplink gain and keep the uplink output power of repeater within 37 dBm
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.
f)Remote mornitoring and maintenance
The repeater has a built-in 4G wireless MODEM. Insert a SIM card to connect to the "Amplitec Helper" cloud platform to realize remote monitoring and set the operating parameters of the repeater.
