Introduction
With the popularity of mobile communications, people want to make a call anytime, anywhere,
so the coverage requirement of communication network is higher and higher, but the reality is
not so, sometimes mobile phone signal is not very good, you want to make a smooth call, even in
some places cell phone cannot dial out. in this cases, cell phone signal booster can solve this
problem in a certain extent.
Features
■ AGC(Automatic Gain Control): When the downlink output signal is too strong or self- oscillated,
the uplink and downlink can automatically reduce the gain and reduce the interference signal
■ Self- Oscillation elimination: The system detects self- Oscillation, first reduces the link
gain, then detects the loop, and finds that the self- oscillation is eliminated, the system returns
to normal working state, otherwise, the power is turned off to prevent interference signal.
■ Inactivity Mode: When no user calls, the device is in standby mode, the uplink power amplifier
is switched off, and the static power is decreased by 30%, so as to achieve the purpose of energy
saving.
