Introduction
In the film shooting industry, traditional wired video transmission systems are increasingly unable to meet the demands for flexibility and efficiency in modern film production due to issues such as complex cabling and limited mobility. For instance, in scenarios involving dynamic scene shooting, drone aerial photography, or multi-camera coordination, wired transmission often results in restricted shooting angles, difficulties in equipment movement, and potential delays caused by cable failures.
Additionally, traditional wireless transmission technologies (e.g., microwave) suffer from poor image quality, high latency, and weak anti-interference capabilities, making them unsuitable for high-definition shooting and real-time monitoring.

Background
In this context, the IWAVE's wireless video transmission module has emerged as an innovative solution for the film shooting industry, thanks to its non-line-of-sight (NLOS) communication capabilities, high bandwidth, and low latency. This module is particularly well-suited for long-distance real-time video transmission in complex environments, such as large outdoor scene shooting, drone aerial photography, and multi-camera live broadcasting.
Project Plan
1.Application Scenarios and Requirements
Multi-Camera Coordination Shooting:
In large-scale film or TV show productions, multiple mobile cameras need to transmit high-definition footage back to the control room in real time, allowing directors to adjust shots instantly.
Drone Aerial Photography：
When drones are equipped with cameras for high-altitude or long-distance shooting, they require stable transmission of 4K/8K footage with low-latency control command feedback.
Outdoor Complex Environment Shooting
In non-line-of-sight scenarios such as mountains, forests, or densely populated urban areas, signal obstruction issues must be overcome.
2. System Architecture Design
Hardware Deployment:
The FDM-66MN transmitter module is integrated into the camera, supporting IP interface input and, if necessary, HDMI/SDI, making it compatible with mainstream cinema-grade cameras (e.g., ARRI Alexa, RED Komodo).
The receiver is deployed in the broadcast van or post-production center, with multi-channel receiving devices enabling signal aggregation and synchronization.
Cascaded transmission (e.g., relay nodes) is supported, extending the transmission distance to over 10 kilometers.
Network Configuration:
The module employs dynamic spectrum allocation technology to avoid interference with other wireless devices on-site (e.g., WiFi, walkie-talkies).
Encryption protocols ensure video data security, preventing content leaks.
3. Application Cases
Case 1: Large-Scale Outdoor Reality Show Shooting
During the shooting of a reality show in mountainous areas, the FDM-66MN module was used for signal transmission between multiple mobile cameras and drones. Relay nodes enabled signal coverage in non-line-of-sight environments, achieving a transmission distance of 8 kilometers, with a latency of less than 50ms and support for 4K/60fps real-time monitoring.
Case 2: War Scene Shooting for a Movie
In a battlefield scene with intensive explosion effects, the module's anti-interference capabilities ensured stable transmission of multi-camera footage, while its encryption feature protected unreleased content.
Advantages
1. Technical Parameters and Performance Highlights
Transmission Distance: Supports over 10 kilometers in line-of-sight conditions and 1-3 kilometers per hop in non-line-of-sight environments.
Bandwidth and Resolution: Supports up to 8K/30fps or 4K/60fps, with adjustable bitrates (10-30Mbps), and is compatible with H.265 encoding to reduce data volume.
Latency Control:End-to-end transmission latency is ≤50ms, meeting the requirements for real-time monitoring and synchronized editing.
Anti-Interference Capability: Utilizes MIMO-OFDM technology and dynamic frequency hopping to adapt to complex interference environments.
Security: Supports AES-128 encryption, complying with the film industry's content confidentiality requirements.
2. Breakthroughs Compared to Traditional Solutions
Non-Line-of-Sight Transmission: Through intelligent signal reflection and relay technology, it overcomes the limitations of traditional wireless devices that rely on line-of-sight transmission, making it suitable for urban or natural terrain-obstructed scenarios.
High Compatibility: The modular design allows for quick integration into various shooting equipment (e.g., gimbals, drones, handheld stabilizers), reducing modification costs.
Low Power Consumption and Lightweight: With a power consumption of less than 5W and a weight of only 50g, it is ideal for small drones or portable devices.
Value and Future Prospects
The application of the IWAVE's wireless video transmitter significantly enhances the flexibility and efficiency of film shooting, particularly in on-location shooting and special effects production. Its high reliability and low latency provide directors with greater creative freedom. In the future, with the integration of 5G and AI technologies, the module could be further optimized into an intelligent transmission network, enabling adaptive bitrate adjustment and intelligent fault diagnosis, thereby driving the film production industry toward fully wireless and intelligent solutions.
