1.6 2.4/5 GHz MU-MIMO
The 802.11ac standard supports only downlink traffic on the 5 GHz band while 802.11ax supports both
downlink and uplink connectivity on the 2.4GHz and 5GHz bands.
In a Mesh network, a downlink connection means transmitting data from an AP to a WiFi client. The AP
serves as the transmitter and the WiFi client as the receiver. An uplink connection means transmitting
data from a WiFi client to an AP. An Uplink connection means the AP is the receiver and the WiFi client,
the transmitter.
1.7 Multicast (for WX3401-B0 only)
Traditionally, IP packets are transmitted in one of either two ways - Unicast (1 sender to 1 recipient)
or Broadcast (1 sender to everybody on the network). Multicast delivers IP packets to a group of hosts
on the network (1 sender to 1 or more recipients).
