Is it better to use WiFi or fpv for UAV image transmission? What's the difference between them? Their advantages and disadvantages are

It is very good to use FPV for UAV image transmission. The differences, advantages and disadvantages are as follows:

First, the sending method is different.

1, WIFI: data transmission requires the sender and the receiver to establish a communication handshake mechanism first, and then transmit each data packet with a size of 5 12 bytes.

2.FPV: One-way image transmission is used for data transmission, which is similar to the data transmission form of TV broadcast towers located in high places.

Second, the sending requirements are different.

1, WIFI: It is a very fast wireless transmission technology, but the two-way handshake mechanism based on TCP/IP protocol can easily cause WiFi image transmission to be unable to transmit aerial images in real time.

2.FPV: On the premise of high real-time requirement, resending the data packet will make the controller unable to see the real-time picture.

Third, the advantages and disadvantages are different.

1, WIFI: the solution is cheap because the PC market demand is huge, which brings scale effect to chip manufacturers, thus reducing production costs.

2.FPV: When the image is transmitted to the limit distance, stripes and weak signals will appear on the screen. When the signal is insufficient or lost, the pilot can check the remote control to get a reminder, stop flying in time or hover the plane.
