INTRODUCTION

What is DUAL-BAND?

Dual-band transmission technology allows it to stream video via 2.4GHz and 5GHz Wi-Fi at the same time. The receiver can then intelligently identify interference and combine the two streams to form the complete audio and video stream.

ENHANCED TRANSMISSION

Understanding DUAL-BAND

Unlike other competing systems, Accsoon transmits two identical copies of your camera’s video output on both 2.4GHz and 5GHz frequencies at the same time. When these signals arrive at the RX unit they are instantly combined as needed to create the final high-quality video feed. Because Dual-Band transmission technology utilizes both frequencies at the same time it is inherently more stable than its rivals – ensuring a robust signal that excels in combatting interference and navigating around or through objects. Super robust, near real-time transmission of HD video and audio that can reach the length of a football field and is not plagued with drop-outs and black screens.

  • Figure1-a: The original image will be transmitted
  • Figure1-b:The image data lost during transmission
  • Figure1-c: The image received and output via the receiver

The receiver can’t restore the image to the original once the video data is lost during transmission.

Are there any solutions to solve this? The answer is no if the manufacturer keeps using 5~5.8GHz WiFi. But the Accsoon R&D team developed the dual-band technology to solve this, we use both 2.4GHz and 5~5.8GHz WiFi and use the two WiFi to transmit the same video & audio data at the same time. With innovative 2.4GHz+5.8GHz Dual-Band Transmission technology, it can intelligently identify interference during transmission, and then combine the data from these two streams to form the complete audio and video signal, greatly improving its stability and anti-interference capability.

Here are some figures to show how the dual-band works.

  • Figure2-b:The image data lost during transmission
  • Figure2-c: The image received and output via the receiver

As the Figure 2, the transmission still lost some data if there is interference.

  • Figure3-b:The image data lost during transmission
  • Figure3-c: The image received and output via the receiver

As the Figure 3, the transmission still lost some data if there is interference.

What will happen if we combine Figure 2-c and Figure 3-c? Yes, an image the same as the original will get and that’s what dual-band is used for. The build algorithm will identify which data was lost via 2.4GHz and 5GHz transmission separately and combine the received data together, then restore and generate an image the same as the original.

Maybe you have a question, what will happen if the lost data is the same on 2.4GHz and 5GHz? This will happen but is almost not possible, why? According to the wireless communication theory, an interference source usually can only generate a specific frequency so it can only interfere with one frequency, plus the time needed to transmit a frame of video is very short, so the chance that loss same data on 2.4GHz and 5GHz is very low and we can ignore that.
