High Quality Waterproof 800MHz 900MHz B20 B8 Dual-Band Bandwidth Adjustable Digital Repeater

 

Product Description

Model: SRD-33DRLG

The Digital Repeater is designed to provide a more cost-effective solution than adding a new Base Transceiver Station (BTS) to improve signal coverage and communication quality in mobile communication system. And its easy installation and maintenance can help carrier get fast return.

The repeater is working as a relay between the BTS and mobiles. It receives the low-power signal from BTS via the Donor Antenna, linearly amplifies the signal and then retransmits it via the Coverage Antenna to the weak/blind coverage area. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction.


Features:

1. Aluminum-alloy casing with IP65 protection has high resistance to dust, water and corrosion
2. DSP Module supporting up to 3 sub-bands adjustable in each frequency band
3. Low interference to BTS by adopting linear amplifier with high gain and low noise
4. Adopting filter with highly selectivity and low insertion loss eliminates interference between uplink and downlink
5. USB port provides a link to a notebook for local supervision or IP Based NMS (Network Management System) that can remotely supervise repeater's working status and download operational parameters to the repeater via Ethernet.

Application:

To expand signal coverage or fill signal blind area where signal is weak or unavailable.

 

Outdoor:	Airports, tourism regions, golf courses, tunnels, factories, mining districts, villages, …
Indoor:	Hotels, exhibition centers, basements, shopping malls, offices, parking lots, …
