The EMTS Triple-Band Digital Mini Repeater is a compact, high-performance signal enhancement solution supporting 4G (LTE) and 5G technologies. It covers 700 MHz (Band 28, FDD), 1800 MHz (Band 3, FDD), and 2600 MHz (Band 41, TDD) frequency bands, making it ideal for improving 4G and 5G coverage in indoor environments. Engineered for intelligent coverage extension, the repeater delivers reliable indoor signal distribution across up to 1500 square meters, efficiently supporting both voice and high-speed data services in low-signal environments such as buildings, underground areas, and commercial zones. This solution is cost-effective, quick to install, and designed to meet modern carrier-grade demands for quality of service and network reliability.
EMTS Telecom Services Ltd. offers a comprehensive portfolio of enhanced coverage solutions for Wireless Networks, in-building coverage. Regardless of the technology or frequency, EMTS can provide customized coverage solutions that address any combination of unique and complex network needs for Wireless Networks.
Key Features
