What is the BD502i?

Hytera's BD502i two-way radios are compact and rugged radios that provide professional communication in an easy-to-use package. The BD502i features analog and digital (DMR) operation, 3 Zones, 48 channels, clear digital audio, extended talk range over analog only radios, and based on TDMA technology, the radio can work longer, up to 22 hours in digital mode (2000mAh Battery).

The BD502i is designed and tested to meet Military Standards 810 C, D, E, F and G, including temperature shock, vibration, high/low temperature and humidity. IP54 dust- and water-proof design guarantees the reliability in different environments.

BD502i can support both analog and digital modes on the same radio. You can easily switch between the operational modes which helps you to communicate with analog and digital radios.  With digital encoding and correction technology, human voice is transmitted much clearer without background noise, even from great distances. This is the next generation audio quality experience.
