ABOUT US

DMR858M is a cost-effective 5W full-function digital walkie-talkie module developed by our company. It is compatible with analog walkie-talkie commonly used in the market and features the DMR Tier II digital walkie-talkie functionality. The module comes with an integrated Moto AMBE++ vocoder. Inside the module, components such as the microcontroller, digital walkie-talkie chip, RF power amplifier, and audio amplifier are all integrated.

it integrates 5W transmission power, dual-mode support for both DMR digital and analog communication protocols, -122 dBm high receiving sensitivity, and a full range of intercom features including relay, SMS, and low power consumption. This highly integrated, high-performance-density design offers a practical solution for devices that are space-constrained but require robust communication capabilities.

DMR818S-5W module supports the DMR Tier II standard and integrates the Moto AMBE++ vocoder, delivering clear and natural voice quality across various communication scenarios.

LoRa1120 supports Sub-GHz, 2.4GHz, and S-band frequencies, making it suitable for global IoT communications. The Sub-GHz band offers excellent long-range transmission with receiver sensitivity reaching up to -144 dBm, significantly enhancing weak signal reception.

LoRa spread spectrum technology effectively combines low power consumption with long-distance communication. Thanks to its strong anti-interference capability, high reception sensitivity, and robust coverage, this technology has been widely applied in IoT scenarios such as smart cities, industrial automation, and agricultural monitoring.
