To maintain the resilience of the link, the system uses Dynamic Frequency Selection (DFS) to automatically choose the best available WiFi channel. Beamforming Technology is also utilised between the transmitter and receiver, limiting interference from other 5GHz users. In addition, Adaptive Variable Bit Rate prevents sudden ‘black screen’ disconnection. Altogether, it’s a unique combination that means that the CW-F25 delivers greater reliability than any other wireless system using WiFi channels.

The system provides license-free operation and is certified for use in Europe. It releases camera operators from having to use expensive licensed channel or cable systems, providing creative flexibility through a cost-effective solution.

Enhancements and user-friendly features
The new CW-F25 uses worldwide standard 802.11n technology. To mix seamlessly with wired camera systems, 4 x 4MIMO channels are utilized with ODFM/64QAM modulation achieving a maximum data rate of 300Mbps. This supports H.264/25 Mbps high profile video with 4 channels of high quality embedded PCM audio.

To ensure the camera operator feels part of the production team, return video, intercom, tally and RS-422 remote control are supported over the link. Ethernet I/O at both Tx and Rx creates a wireless bridge to support an IP camera feed, remote controller or other data link.
