The latest generation of Wi-Fi signaling is based on the IEEE 802.11ac standard that works in the 5 GHz Wi-Fi band. This standard extends the maximum number of MIMO streams to 8 and provides support for MU-MIMO that allows the multiple streams to be used for different users rather than a set of transmitting and receiving user pair. 802.11ac also offers backward compatibility to 802.11b/g/n and can provide bandwidth up to 1.3 Gbps on the 5 GHz band. 802.11ac also allows the use of 80 MHz channels (mandatory as per specification) and 160 MHz (optional). This increases the data rates available and hence the bandwidth over 802.11ac. The specification also allows the use of bonding two non-contiguous 80 MHz channels to form a single ...
