What do i really need?
Music streaming >
You should have no problem streaming music around your home. Songs from the iTunes Store and Apple Music use around 256Kbps (Kilobits per second), while higher quality Apple Lossless tracks – an option for importing your own CDs – use more bandwidth.
Video streaming >
Video can be intensive on bandwidth. Netflix suggests download speeds of 3Mbps for SD video, 5Mbps for 720p HD video and 25Mbps for Ultra HD per stream. How smoothly video streams also depends who else is using your network and your setup.
Video conferencing >
If you love chatting face-toface, count on using similar bandwidth as for streaming video. Skype, for example, recommends 300Kbps for video calling, 500Kbps for higher quality, and 1.5Mbps for HD video. FaceTime needs 1Mbps for HD video.
