N150 Wireless Micro USB Adapter WNA1000M • Streaming HD video requires 10 to 30 Mbps per stream. Because latency and packet loss can disrupt your video, plan to provide at least twice the capacity you need. • Streaming MP3 audio requires less than 1 Mbps per stream and does not strain most modern networks. Like video, however, streaming audio is also sensitive to latency and packet loss, so a congested network or a noisy link can cause problems. • Backing up computers over the network has become popular due to the availability of inexpensive mass storage.
