COFDM 2W Video-Audio-Transceiver mit großer Reichweite für Roboter

Q: Q1: What’s the range of COFDM 2W Long-Range Video Audio Transceiver?

A1: Typically 1–2 km near the ground, and up to 4–8 km in clear LOS conditions (depends on environment and antenna height).

Q: Q2: What is the system delay?

A2: Video + Audio latency: 150–300 ms ; Data latency: ~40 ms .

Q: Q3: Can it support two-way data?

A: Yes. It supports bidirectional RS232/RS485 data and two-way voice intercom simultaneously.

Q: Q4: Can it be made smaller or lower power (2W)?

A: Yes, a compact 2W version (13×10×3.7 cm) is available.

Q: Q5: Why does video blur when moving fast?

A: It’s caused by dynamic video compression — a trade-off to maintain real-time low latency .

Customer Inquiry about COFDM 2W Long-Range Video Audio Transceiver for Robots

“I’m looking for a transmitter and receiver, COFDM mit Zwei-Wege-Audio und Einweg-Video, long range, I think 2W might be fine.”

This is a very typical inquiry from professionals working with Bodenroboter, 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.

Quad Video Transmitter with Data Audio Transceiver for Robot or Mini Remote Operated Vehicle — Quad-Videosender mit Daten-Audio-Transceiver für Roboter oder ferngesteuerte Minifahrzeuge

Understanding the Customer’s Needs

The customer clearly wants:

COFDM-Technologie for robust, anti-interference transmission.
Zwei-Wege-Audio for live communication between operator and robot.
Einwegvideo to send clear, low-latency visuals from robot to operator.
2W transmit power für medium-to-long range Betrieb (1–2km, even close to the ground).

Such a setup is typically used in robot dogs (beim UGV), bomb disposal robots, und inspection vehicles, where maintaining real-time video, Kontrolle, and voice contact is critical.
