The GLOHE GMD9000 is a professional DMR digital repeater designed to extend reliable two-way radio coverage for commercial and industrial communication systems. Available in VHF 136–174MHz or UHF 400–470MHz versions, it supports analog and digital operation, two-slot TDMA and selectable 5W, 10W, 30W or 50W transmit power.
The GLOHE GMD9000 is a professional DMR digital repeater developed to improve signal coverage and communication reliability across commercial buildings, factories, warehouses, campuses, transportation facilities and other demanding radio communication environments.
Available in VHF 136–174MHz or UHF 400–470MHz versions, the D9000 supports both analog and digital communication, allowing organizations to upgrade an existing analog radio system to DMR digital communication more easily. Its 16-channel capacity, 12.5kHz/25kHz channel spacing and selectable 5W, 10W, 30W or 50W transmit power provide the flexibility required for different coverage areas and system configurations.
The two-slot TDMA system allows digital channels to support two voice streams, improving frequency efficiency. A large HD display provides clear operating information, while adjustable volume, colour code switching, external microphone support and external duplexer compatibility simplify system operation and installation.
Designed with effective thermal management and support for optional IP interconnection, the D9000 is a practical repeater solution for distributors, system integrators and professional communication network projects.
