speaker Mic for Radioworx G9 4g poc radio

Specially designed for the Radioworx G9 Radio, with internal rechargeable battery via a type "C” connection on the Mic.

Please note: These Mics are not available anywhere else.

Why 4G Radio Speaker Mics Require Battery Power:

Unlike traditional RF (radio frequency) radios, which rely on analogue or direct RF communication, 4G radios operate on advanced digital networks using cellular or IP-based technology. This fundamental difference in design and functionality creates the need for battery-powered speaker microphones. Here’s why:

Digital Signal Processing (DSP):
4G radios use complex digital signal processing to transmit and receive audio over cellular networks. The speaker Mic must encode and decode these signals, a process requiring dedicated electronic components that consume power.

Independent Microprocessor Functionality:
Many 4G speaker Mics are equipped with their own microprocessors for advanced features like noise cancellation, push-to-talk (PTT) over IP, and enhanced audio quality. These processors cannot draw power directly from the radio and require an independent power source.

Two-Way Communication Architecture:
Traditional RF radios typically use the connected mic as a passive accessory, whereas 4G radios often treat the speaker Mic as an active peripheral. For seamless communication and additional features, the speaker Mic must actively participate in the communication process, necessitating its own power.

Advanced Features in Modern Mics:
Many 4G-compatible speaker mics offer added functionality, such as integrated Bluetooth, GPS, or LED indicators for connectivity and status. These features demand a reliable and dedicated power supply, which a separate battery provides.

Energy Demands of 4G Technology:
The digital nature of 4G communication requires more power compared to traditional RF signals. The Mic needs to operate autonomously to handle these requirements, which would otherwise strain the radio's internal power supply.

Battery Life Optimization for the Radio:
By using a separate battery for the Mic, the radio’s main battery is conserved for its core communication functions, ensuring longer operational time in critical scenarios.

This battery-powered design ensures optimal performance, reliability, and the inclusion of advanced features that enhance the user experience. It's a necessary evolution to align with the complex and powerful capabilities of 4G communication systems.
