The EMTS Telecom Services Digital RF Power Repeater boosts LTE coverage for Band 3 (1800 MHz) and Band 7 (2600 MHz) in private and public LTE networks. Designed for large indoor and outdoor sites — industrial campuses, utility facilities, transport corridors, and rural broadband — this dual-band repeater ensures stable, high-quality signal distribution. Advanced DSP independently filters, amplifies, and regenerates uplink and downlink signals while minimizing adjacent-band interference for optimal spectral efficiency and link performance. Housed in a rugged enclosure, onboard microcontrollers continuously monitor gain, temperature, voltage, and faults. Management and remote supervision are available via USB, Wi-Fi app, or optional integrated modem, with full integration into the EMTS Network Management System (NMS) for real-time configuration and alarms. A compliant IMOP algorithm prevents oscillation caused by poor isolation between donor and service antennas, and an optional ICS mechanism enables operation with isolation as low as Gain – 10 dB. EMTS Telecom Services Ltd. offers a comprehensive portfolio of enhanced coverage solutions for the Wireless
