Line Amplifier 40dBm DCS1800MHz WCDMA2100MHz High Power Dual Band Mobile Phone Signal Repeater
Model: GW-40DW-LA
Line Amplifier Product Description:
The Dual Band Trunk Amplifier is designed to provide a more cost-effective solution than adding a new Base Transceiver Station (BTS) to extend signal coverage and to improve communication quality in triple system. And its easy installation and maintenance can help carrier get fast return.
The Trunk Amplifier is working as a relay between the BTS and distributed antennas. It receives the low-power signal from Trunk line of indoor distribution system via the coupler, linearly amplifies the signal and then retransmits it via the cables to the antenna distribution system. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction.
Line Amplifier Features:
Line Amplifier Applications:
To expand signal coverage or fill signal blind area where signal is weak or unavailable.
Indoor: Hotels, exhibition centers, basements, shopping malls, offices, parking lots, …
