Thought cat5e cannot transmit full HD movie of 1080p.
I wonder where you get this information? Cat5e are able to go at 1000Mbps max length 100meter. That is the reason it called Cat 5e (enhance)
Say using 100Mbps speed data transmission, assuming conventional house PC equipments able to handle such high bandwidth
- 100Mbps / 8 = 12.5MBps (Mega Bytes per sec),
- 12.5Mbps - 20% (Max overhead) = 10MBps
- 10MBps x 60 = 600 Megabytes per min
- 600MB / min x 60 = 36,000 MB / hours
So you think 36 Gig per hours enough for Full HD? Even run at 1/2 the speed you get full HD for one movie.
FYI, technically Full HD is 1920x1080, = 2,073,600 Pixels , using 2bytes per pixels 32bits color , you get 4,147,200 Bytes / sec. Voice will not be that much maybe 1MB / sec. Which add up to about 5MB per sec maybe 6MB per sec. This are all without compression, and most transmission come with video and voice compression which will reduce the size.
So you think Cat5e enough? even at 100MBps is already enough. Most important, use good quality cable.
Cat 6a is rate to go up to 10Gbps (theoretically)
In some of my office, we run Cat 5e with 1Gbps without any problem.
