Hello, I have two buildings 30 meters apart. I do  a lot of streaming and video uploading will a pair of CPE510 do the job and give me a good performance. kind regards Doug W.

Maximum WiFi speed for CPE510 is 300 Mbps, protocol overhead in 802.11n is ~30%, so WiFi speed is effectively ~210 Mbps half-duplex. This allows ~100 Mbps full-duplex data speed in an ideal environment, which yields ~80-90 Mbps real throughput in practice. Of course, actual throughput depends on many environmental parameters such as interferences, fresnel zone clearance etc. and a good antenna alignment. See this story for more information.
