List of Four Stream Hardware

802.11n supports up to four spatial streams but very few four-stream 802.11n-only devices were ever released.

Only examples currently exist in the database. These are mostly media bridge type devices provided
 * by cable and satellite TV providers to provide service to set-top boxes located throughout the home.

Two four-stream 802.11n-only adapters exist but they are using 802.11ac
 * hardware without 5GHz 802.11ac support implemented.
 * Compex WLE1200V2-22, Zcomax AC-921

802.11ac supports up to 8 spatial streams. Four-stream implementations
 * are becoming more common in the latest 802.11ac hardware.
