I have two questions:
1- If I want to transfer a photo via bluetooth, how should I find how long it takes to transfer? I mean the formula between the image size, bluetooth bandwidth and time.
2- If I want to transfer video in real time, how should I calculate the bandwidth is needed to transfer the video via bluetooth/WiFi? What's the formula between video resolution(VGA,2K,4K,etc) and transferring bandwidth if we want to do it in real-time?
For example: If I have 1920*1080*30(fps) video, I think I should multiply it by 3 or 4(respect to colored image type) then I have about 180~240 million bytes to transfer per second. So it means I need about 200MBps bit-rate! And I only should use 802.11n protocol for that!
Did I calculate the things right?
EDIT: I found this calculator that I am not sure but I think it's the thing I was looking for (https://www.cctvcalculator.net/en/calculations/bandwidth-calculator/). what do you think about this? Why does it calculate local bandwidth bigger than network bandwidth? it's strange for me!
