Interference between different radio frequencies can be a time-consuming issue for camera crews. The ARRI Wireless Video System eliminates this issue because it works harmoniously with ALEXA SXT W’s other radio-based offerings: the WiFi and the ECS, ARRI’s proprietary camera and lens control system. Since ARRI now fulfills all wireless requirements, crews can be sure there won’t be any problems on set. The high-quality video feeds from the ALEXA SXT W and stand-alone transmitters are long-range, uncompressed, and encrypted for safety. Audio, timecode, and REC flag are included in the zero-delay signal, and up to four receivers can be used per transmitter.

Interesting about: Audio, timecode, and REC flag are included in the zero-delay signal, and up to four receivers can be used per transmitter.
NAB is coming. If anyone can ask which frequencies works and audio / timecode; will be great.
