Band 3 + n78 1800/3500MHz 20dBm Digital Mini Repeater
The EMTS Telecom Services dual-band 1800/3500MHz Digital Mini Repeaters (DMR) offer an excellent solution for addressing poor signal coverage and is suitable for both coverage extension and indoor applications.
This product line repeaters are designed to support dual-band 1800MHz FDD and 3500MHz TDD frequencies, accommodating both LTE and 5G technologies.
Equipped with an intelligent algorithm, the DMR minimizes potential uplink interference and includes an isolation detection function to alert users when the distance between donor and service antennas is insufficient. Its easy installation and friendly GUI make the DMR an outstanding choice for enhancing signal strength, thereby improving the coverage and capacity of LTE/5G networks.
The EMTS DMR enhances mobile network capacity and data coverage in areas with weak signals. It provides a cost-effective solution for indoor signal issues caused by architectural obstacles and signal attenuation. The simplicity of installation and maintenance ensures a quick return on investment for carriers.
The DMR employs advanced digital technology, accessible via EMTS Mobile Apps or a direct USB connection. It features cutting-edge RF technology and digital modules to reduce power consumption and increase the MTBF's reliability, incorporating an IMOP algorithm to prevent self-oscillation, ensuring stable and reliable performance.
EMTS Telecom Services Ltd. offers a comprehensive portfolio of enhanced coverage solutions for the Wireless Wireless Networks.
