High Power pickup Repeater (BDA) In 19″ Enclosure
The EMTS TETRA Band selective Power Repeaters (BDA) provide an excellent solution for in-building
applications for poor signal coverage or outdoor coverage extension. Typical applications are Airports,
Tourism regions, tunnels, factories, mining districts, villages, Hotels, exhibition centers, basements, shopping
malls, offices, parking lots, and others. With the Repeater, the TETRA or TETRAPOL operator can quickly
expand a base station's service area by filling in coverage holes caused by terrain, buildings, or tunnels. The
Repeater amplifies the TETRA or TETRAPOL handset signals and base stations and can be used in dead
areas where service is poor. The Repeater is connected to an outdoor 'donor' antenna using a coaxial cable.
The donor antenna transmits signals from mobile phones and receives signals from the BTS. Easy installation,
lightweight design, and very friendly GUI make our Repeater easy to use and install.
Key Features
- 19-inch enclosure for rack mounting installation (optional IP65 outdoor enclosure)
- Bidirectional Amplifier configuration for off-air compliance with TETRA & CE standards
- Support Band or Channel Selective for TETRA or DMR networks
- Provide quick RF coverage extension to TETRA Base-Station using fiber or coax DAS
- Metal cavity filter technology allows wider receiving/transmitting separation, higher stability, and lower noise figure
- Intelligent design, with a built-in ALC function, provides auto amplitude compensation
- USB port for local supervision, the built-in 3G/4G modem to communicate for remote management and configuration, and WIFI connectivity for local settings via mobile app
