Hytera BD502i
Rugged Durability. Extended Range. Effortless Operation.
Hytera BD502i Commercial DMR Two-Way Radio
The Hytera BD502i is a powerful, business-grade Digital Mobile Radio (DMR) engineered for demanding environments. Offering higher power output than entry-level models and built to strict military standards, it provides extended coverage and exceptional audio clarity across warehouses, construction sites, and manufacturing floors. With automatic analog-to-digital switching and a rugged, no-nonsense design, the BD502i is the ultimate everyday workhorse for teams that require reliable, long-range communication without the complexity of a screen.
UPGRADE YOUR FLEET WITH RUGGED DIGITAL CLARITY TODAY.
High-Gain Whip Antenna
Voice-Announced Channel Knob
Tactile PTT & Programmable Key
Secure Accessory Connector
Analog & Digital Auto-Detect
Streamline your migration process. The BD502i intelligently listens to the channel and automatically detects whether an incoming transmission is analog or digital, instantly switching modes to receive the call. Your users can seamlessly reply in the same mode simply by pressing the PTT button within the call hang time, ensuring zero missed messages during a mixed-fleet transition.
Extended Range and Power Output
When distance matters, the BD502i delivers. Operating at up to 5 Watts on VHF and 4 Watts on UHF, this device punches through interference to deliver a significantly wider coverage footprint than standard entry-level radios. If your operations expand, the radio fully supports DMR Tier II repeaters, allowing you to easily scale your network and boost signal strength even further.
Advanced Anti-Interference Audio
Loud machinery and heavy equipment are no match for digital error-correction technology. The BD502i utilizes an advanced digital vocoder that aggressively filters out background noise and suppresses channel interference, ensuring your voice is delivered with sharp, professional clarity even in the noisiest industrial environments.
Pseudo Trunking Efficiency
Maximize your radio spectrum. Utilizing Hytera’s virtual trunking feature, the BD502i automatically searches for and utilizes whichever digital time slot is currently free. This dramatically improves frequency efficiency and call connectivity during high-traffic scenarios, ensuring critical messages get through when the channels are busy.

Site Walk & Coverage Testing
Upgrading to higher-wattage equipment changes your operational footprint. Before deployment, we can conduct thorough on-site RF testing.
Our technicians analyze your building materials, check for localized interference, and physically verify that your new BD502i fleet will provide total wall-to-wall coverage across your entire facility.
Fleet Management & Maintenance
Managing a large deployment of rugged equipment in an industrial setting requires organization.
We assist with asset tracking, battery maintenance plans, and multi-unit charging station configurations, ensuring that every shift has fully charged, fully functional equipment ready to go the moment they clock in.
Repeater Integration
If your business has outgrown radio-to-radio (simplex) communication, we can help you take the next step.
Because the BD502i is fully compatible with DMR Tier II repeaters, our engineering team can design, install, and license a central repeater system that doubles your channel capacity and drastically amplifies your talk range.
Worker Safety Programming
The BD502i features essential safety capabilities that need to be expertly configured to be effective.
We customize your codeplugs to establish dedicated emergency broadcast channels, program the one-touch panic buttons, and enable VOX (voice-activated transmit) for workers who need their hands free to operate heavy machinery.
