Hytera HP68x Series (DMR)
Slim, MIL-spec DMR portable with AI noise cancellation and 30-hour battery — the workhorse radio for airside and terminal staff.
The Hytera HP68X is a compact professional DMR portable radio in the HP6 series, available in UHF (400–527 MHz) and VHF (136–174 MHz) variants with model suffixes HP682, HP685, HP686 and HP688 differentiating keypad, GPS and Bluetooth configurations. The design priority is a long-shift wearable: at 280 g with a 2,000 mAh battery and a 122 × 55 × 31.5 mm profile, it sits comfortably in a chest holster or belt clip through a 12-hour airside shift without the bulk associated with ruggedised portables.
The radio's AI-based noise cancellation algorithm is rated to suppress up to 30 dB of background noise and howling — the kind of continuous broadband noise generated by jet engines at idle, APU exhaust, and baggage conveyor systems. A water-porting speaker design drains water from the cavity after immersion, maintaining audio output after the IP67 / IP68 dunking events that are routine on apron duty. The 3,000 mAh battery option extends runtime to 30 hours under a 5-5-90 duty cycle, covering extended shifts or battery-sharing scenarios.
DMR Tier II support (conventional and some variants support trunked) makes the HP68X compatible with the airport's existing DMR repeater infrastructure without a full TETRA migration. Bluetooth 5.0 connects to wireless earpieces and speaker-microphones, keeping the radio body-worn in high-noise areas. GNSS positioning enables individual tracking in the SmartOne Dispatch system. MIL-STD-810H certification covers a 2-metre drop test — a representative event for a ramp radio dropped from standing height onto tarmac.

Use cases.
- ›Ramp ground-handling staff (marshalling, loading, fuelling) needing a slim, all-shift DMR radio without TETRA network dependency
- ›Terminal operations — check-in supervision, gate coordination, passenger-handling staff in concourse environments
- ›Airport security patrols and access-control teams where Bluetooth wireless earpiece use is required for discreet operation
- ›Maintenance and facilities teams on large airport campuses needing GNSS tracking through the dispatch system
- ›Airlines and ground handlers operating owned DMR repeater infrastructure independent of the airport's core TETRA network
- ›High-temperature ramp environments in the GCC where the −30 °C to +60 °C operating range and sealed speaker handle dust and heat without degradation
