 The Linksys MR8300 is a MU-MIMO Tri-Band WiFi router, which has one 2.4GHz and two 5GHz WiFi Interfaces, making it an interesting choice for wireless backhaul or repeater applications. The radios support MCS 0-9 (up through 256 QAM) for devices and paths that are compatible with those high-density modulations. The Linksys MR8300 is a MU-MIMO Tri-Band WiFi router, which has one 2.4GHz and two 5GHz WiFi Interfaces, making it an interesting choice for wireless backhaul or repeater applications.
