Like Zoom, Skype also provides a support page to explain their bandwidth details. Now, let us boil down all those kilobits into a language you can understand: Type of Call Quality Bits per second Bytes per minute Total per Hour 1:1 Standard 600kbps 9 MBs 540 MBs 1:1 720p HD 1.2Mbps 16 MBs 1.08 GB 1:1 1080p HD 3.8 Mbps 50 MBs 3 GB Group Standard 1.0 Mbps/600 Kbps 10.5 MBs 630 MBs Group 720p HD 2.6/1.8 mbps 29 MBs 1.7 GB Group 1080p HD 3.8/3.0 Mbps 68 MBs 4 GB Group Gallery 2.0/4.0 Mbps 30 MBs 1.8 GB
Gallery viewing: 25 views = 2.0 Mbps, 49 views = 4.0 Mbps Standard quality: up/down of 1.0 Mbps/600 KbpsĢ. 720p HD quality: to 1.2 Mbps (megabits per second)ģ. Standard quality: 600kbps (kilobits per second)Ģ.
