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?& rdquo;
เข้าใจความต้องการของลูกค้า
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 เมตร, 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 กิกะเฮิรตซ์หรือ 5.8 GHz—suffer heavy signal attenuation when trees, ความชื้น, and terrain block line of sight. For this type of environment, ก COFDM (การเข้ารหัสการแบ่งความถี่แบบตั้งฉากแบบเข้ารหัส) system provides a far more stable solution.

คำถามที่พบบ่อย
คำถามที่ 1: 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.
คำถามที่ 2: What range can we expect in a dense rainforest?
Typically 1–3 km, depending on antenna type, ความสูง, and frequency band. Lower frequencies achieve better penetration.
ไตรมาสที่ 3: Can I transmit control data along with the video?
ใช่. Our system supports transparent data return channels for bi-directional communication.
ไตรมาสที่ 4: Is the system compatible with my current cameras?
ใช่. It supports HDMI, เอสดีไอ, or AV input and can be adapted for IP cameras.
บทสรุป
For researchers and developers working in challenging environments like rainforests, traditional wireless systems simply cannot provide the stability and range required. ก COFDM-based H.265 low-latency transceiver ensures reliable, เข้ารหัส, and real-time communication — essential for mission success in field robotics and exploration.
