Kopernavraag oor COFDM Wireless Link vir Forest Robot Research.
“Ek is 'n navorser by die Universiteit van São Paulo in Brasilië. Ons ontwikkel 'n grondrobot om die reënwoud te verken en monsters te versamel. Ons gebruik 'n radio van 'n ander vervaardiger om die beeld en opdragte tussen die ontvanger en die sender oor te dra. Maar die probleem waarmee ons te kampe het, is met betrekking tot die transmissieafstand. Wanneer die robot die bos binnegaan, die maksimum afstand wat ons bereik 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?”
Verstaan die kliënt se behoeftes
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 meter, 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, vog, and terrain block line of sight. For this type of environment, a COFDM (Gekodeerde Ortogonale Frekwensie Vermenigvuldiging) system provides a far more stable solution.

H.265 COFDM Wireless Video Transmitter & Ontvanger
This professional-grade wireless link is specifically designed for nie-siglyn (NLOS) applications such as forests, tunnels, and urban areas. Dit ondersteun long-range HD video and data transmission met ultra-lae latensie, ensuring real-time monitoring and reliable robot control.
Belangrike kenmerke
- Frekwensieband: 300 MHz – 900 MHz (aanpasbaar, supports low-frequency penetration)
- Output Power: 1 W – 2 W for extended range
- Benewens hoë kwaliteit video- en klankvereistes van die kamera: Op na 1 - 3 km in dense forest conditions
- Video kompressie: H.265 for efficient and high-quality streaming
- Vertraging: As low as 30 ms
- Data Interface: Ethernet / DVB-T/DVB-T2 COFDM Standaarde module met Diversiteit / RS232 for control signal return
- Enkripsie: AES128 private secure link
- Vormfaktor: Kompak, liggewig, and rugged – ideal for field robotics
Tipiese toepassings
- Forest and environmental research robots
- Rescue or inspection ground robots
- UAV or UGV video links
- Defense and reconnaissance systems
- Remote wildlife observation or monitoring
Vrae
V1: Hoekom COFDM in plaas van Wi-Fi of analoog radio?
COFDM provides strong anti-interference and multi-path resistance, die handhawing van 'n stabiele beeld selfs onder NLOS-toestande waar Wi-Fi misluk.
V2: Watter reeks kan ons verwag in 'n digte reënwoud?
Tipies 1–3 km, afhangende van die tipe antenna, hoogte, en frekwensieband. Laer frekwensies bereik beter penetrasie.
V3: Kan ek beheerdata saam met die video oordra?
Ja. Ons stelsel ondersteun deursigtige data-terugsendingkanale vir tweerigtingkommunikasie.
V4: Is die stelsel versoenbaar met my huidige kameras?
Ja. Dit ondersteun HDMI, SDI, of AV-invoer en kan aangepas word vir IP-kameras.
Konklusie
Vir navorsers en ontwikkelaars wat in uitdagende omgewings soos reënwoude, tradisionele draadlose stelsels kan eenvoudig nie die stabiliteit en omvang verskaf wat benodig word nie. A COFDM-gebaseerde H.265 lae-latency-senderontvanger verseker betroubaar, geïnkripteer, en intydse kommunikasie - noodsaaklik vir missiesukses in veldrobotika en eksplorasie.
