Hytera HM652
HM652 DMR Mobile Radio
The Hytera HM652 is a compact UHF DMR mobile built for fleet work in trucks, vans, and heavy equipment. It features AI noise cancellation, high receive sensitivity, a remote-control head, and analog and digital modes for clear calls.
Overview Description of the Hytera HM652:
The Hytera HM652 is designed for remote workers and fleet operations that require reliable voice and data connectivity on the road. The compact chassis is lightweight and easy to install, and the handheld control head keeps key actions close to the driver. The HM652 includes three programmable buttons for quick tasks such as power, channel, or contact changes, as well as volume control.
Crystal-Clear Communication in Any Environment
Audio performance is engineered specifically for loud vehicles and high-traffic environments. To ensure you are heard the first time, every time, the HM652 features:
-
AI-Based Noise Cancellation: Using advanced deep-learning algorithms, the radio filters out distracting background sounds like engine roar, wind, and road noise in real-time. This ensures that only clear human speech is transmitted to your team.
-
Automatic Gain Control (AGC): No more “blasting” or “whispering” on the air. AGC automatically adjusts the microphone sensitivity so that whether a user speaks softly or is shouting over a loud engine, the output volume remains steady and natural for the listener.
-
Howling Suppression: This prevents the high-pitched feedback “screech” that often occurs when two radios are used close together in the same cab.
-
High RX Sensitivity: Helps keep calls stable and clear even when you are operating in weak-signal areas.
Flexible Migration and Trunking
This Hytera HM652 model supports both analog and digital modes, making it easy to migrate from legacy analog systems to DMR with minimal disruption. It supports DMR Tier II and, with a license, adds Hytera XPT trunking for multi-site setups, plus roaming between repeater sites. For calling, it supports individual, group, unaddressed group, and all-calls.
Enhanced Safety and Data
For safety, the Hytera HM652 includes a dedicated emergency call button. The Lone Worker feature can be set to prompt check-ins at specific intervals. With a license, Priority Interrupt allows a dispatcher to override an active call with urgent information, and dispatch can also remotely enable or disable units for security.
Beyond voice, the HM652 supports:
-
Data Features: Text messaging, emergency alarms, and GPS reporting (on GPS-enabled models).
-
Gateway Options: Back-to-Back bridging (linking analog/digital signals or different frequencies).
-
Clarity Transmission: A wireless data path between remote devices and a management center.
