Multi-user MIMO Routers Announced

Asus’s new 802.11ac router, the RT-AC87U, is the first commercial router that supports Wave 2 802.11ac, using a chip from Quadtenna.

Wave 2 uses multi-user multiple-input-multiple-output, or MU-MIMO. While MIMO can transmit multiple parallel streams of data over the same spectrum, until now those paralled streams couldn’t go to multiple people simultaneously.
