In terms of standards, Tenda AC9 works with all mainstream wireless standards, including 802.11ac and 802.11n. It is a dual band wireless network with a total maximum bandwidth of 300 Mbps for the 2.4 GHz frequency and 867 Mbps for the 5 GHz frequency. This means a total of 1167 Mbps. Another aspect that is not clear from the official specifications is whether this router offers 2x2 MU-MIMO, as we have seen speculated on some online forums. However, considering the real-life performance that we obtained when testing it, this speculation might be true.
