Transfer speeds will vary based on a number of factors including the camera, file format, tethering software, and computer specifications. When using the faster 5 GHz setting on the Air Direct, the average user will see real-world performance of transfer rates in the 4 – 7 MB/s (Megabyte per second) range.
To estimate the average real-world transfer time of your files, you can divide the file size (in Megabytes) by an average transfer rate of 5.5 MB/s. The result is a rough estimate of the time that it will take to transfer the file via the Air Direct when using the 5 GHz setting. See the example below:
If your camera produces files that are roughly 35 MB. Divide the file size by the average transfer speed (5.5 MB/s) to get a rough estimate of the transfer time:
35 / 5.5 = 6.36
The 35 MB file will take approximately 6.4 seconds to transfer via the Air Direct when set to 5 GHz.
Note: Slower processors, limited computer resources and tethering software image processing can further delay the image before it is available for viewing within the tethering software.
2.4 GHz will transfer at a slower rate. To roughly estimate transfer times on the 2.4 setting, you can double the time estimated using the 5 GHz setting.
