Customer Inquiry about COFDM 2W Long-Range Video Audio Transceiver for Robots
“I’m looking for a transmitter and receiver, COFDM z dwukierunkowym dźwiękiem i jednokierunkowym wideo, duży zasięg, I think 2W might be fine.”
This is a very typical inquiry from professionals working with ground robots, remote vehicles, and mobile command systems, where reliable long-range video and audio communication is essential. Let’s break down the requirements and the perfect product that fits them.

Understanding the Customer’s Needs
The customer clearly wants:
- Technologia COFDM for robust, anti-interference transmission.
- Dwukierunkowe audio for live communication between operator and robot.
- Wideo w jedną stronę to send clear, low-latency visuals from robot to operator.
- 2W transmit power Do medium-to-long range działanie (1–2 km, even close to the ground).
Such a setup is typically used in psy-roboty (w UGV), bomb disposal robots, i inspection vehicles, where maintaining real-time video, kontrola, and voice contact is critical.
