For small-to-medium households: The MyRepublic Wi-Fi Hub+ has AC1600 technology and is also dual band, providing good Wi-Fi Coverage and Data Speeds.

Bandwidth

Wireless-AC has wider bandwidth capabilities of 80 MHz (and an optional 160 MHz). By comparison, older N-Series Routers bandwidth was only 20 or 40 MHz. Imagine the MHz as lanes on a highway: 20 MHz represents 2 lanes and 80 MHz represents 8 lanes. The more lanes available, the larger the amount of data that can pass through simultaneously, giving you the maximum performance connection speed.

MU-MIMO allows communication with 4 different devices at the same time where you only used to be able to connect one. No longer is there a queue of connectivity on a router waiting for availability. With Wireless-AC, more devices can connect instantly to a single router, with less interference or disruptions.

Why have 2 bands?

All MyRepublic routers use wireless-AC  with a choice of  the 5 GHz and 2.4 GHz bands. Most people will use the 5GHz frequency most of the time, but if you are on the edge of your Wi-Fi Router reach, use the 2.4 GHz network as it is slower but more stable when you are further away from your connection point.
