Buyer inquiry about COFDM Wireless Link for Forest Robot Research.
“I am a researcher at the University of São Paulo in Brazil. We are developing a ground robot to explore the rainforest and collect samples. We are using a radio from another manufacturer to transmit the image and commands between the receiver and the transmitter. But the problem we are facing is regarding the transmission distance. When the robot enters the forest, the maximum distance we are achieving is 100 meters between transmitter and receiver, but we need much more than that. I was looking at your communication solutions here and I thought if you didn’t have a product that could help me?”
Comprender las necesidades del cliente
This inquiry comes from a research team developing a forest exploration robot for environmental sampling and data collection. Their main challenge lies in wireless communication through dense rainforest vegetation. Using a standard radio link, their transmission range is limited to around 100 metros, which is insufficient for field operations that demand reliable video and control links over several hundred meters or even kilometers.
The root of the issue is that conventional radios—often operating at 2.4 GHz or 5.8 GHz—suffer heavy signal attenuation when trees, humedad, and terrain block line of sight. For this type of environment, a COFDM (Multiplexación de división de frecuencia ortogonal codificada) system provides a far more stable solution.

Preguntas más frecuentes
Q1: Why COFDM instead of Wi-Fi or analog radio?
COFDM provides strong anti-interference and multi-path resistance, maintaining a stable image even under NLOS conditions where Wi-Fi fails.
Q2: What range can we expect in a dense rainforest?
Typically 1–3 km, depending on antenna type, altura, and frequency band. Lower frequencies achieve better penetration.
Q3: Can I transmit control data along with the video?
si. Our system supports transparent data return channels for bi-directional communication.
Q4: Is the system compatible with my current cameras?
si. It supports HDMI, IDE, or AV input and can be adapted for IP cameras.
Conclusión
For researchers and developers working in challenging environments like rainforests, traditional wireless systems simply cannot provide the stability and range required. UNA COFDM-based H.265 low-latency transceiver ensures reliable, cifrado, and real-time communication — essential for mission success in field robotics and exploration.
