System principle outlined
1.
This product is suitable for WCDMA、CDMA and GSM type of network
。
2.
Cell phone signal amplifier (and amplifier for synonyms hereinafter referred to as the amplifier),
amplifiers, feeder, antenna etc

The amplifier's working principle is descending amplifier through the installation in the OUTDOOR
antenna base station downline weak signal, and then through the rf feeder will signal is introduced
into equipment. Amplifier to the introduction of the weak base station downside signal filter and
amplification, and through the INDOOR antenna will enlarge the signal after launch out to meet
antenna base station downline weak signal, and then through the rf feeder will signal is introduced

Uplink working principle: the amplifier INDOOR antenna to mobile terminal of the uplink signal,
through the rf feeder introduced to the equipment. Equipment will be up for filter and amplification
signal, and then through the rf feeder connected to the OUTDOOR antenna, the signal will launch out.
