COFDM HD wireless video transmission system specifications and performance
14 years old. Gear and prices may have changed since.
What the thread found
- A COFDM HD wireless system operates with 2 frames end-to-end latency using 10 watts power consumption and 500mW RF output across 2.4GHz, 5.8GHz, or L band frequencies.
- The system supports multiple video formats including 720p, 1080i, 1080p, and 1080Psf with automatic format detection and operates without cooling fans.
- Diversity antenna reception with dual antennas can be separated by over 100 feet to improve signal reliability.
- COFDM signal penetration achieves ranges up to 40 miles on 2.4GHz with appropriate panel antennas, and penetrates multiple building walls with omnidirectional antennas achieving 0.5 mile range through 10 or more walls.
- The receiver measures 1U and supports optional HDMI output, encryption, and battery mounting plates for UAV applications with transmitter weight around 160-222 grams.
- System pricing is approximately $18000 for a complete standard configuration, with separate receiver and transmitter units priced at $8300 and $9700 respectively.
Depends on
- This was a product introduction in 2012 with preliminary specifications not yet finalized.
- Performance claims regarding range and wall penetration depend on antenna selection and placement configurations.
- One user noted an existing competing system offered lower latency at lower cost, suggesting this system's advantages may be application-specific rather than universal.
- Specifications and pricing were subject to change prior to production release.
