What’s the difference between the Bridge, the Hub, and the Receiver?

The Bridge works just like two Hubs or a Hub and Receiver, except the Bridge does not provide a WiFi signal for laptops, tablets, smartphones, etc. to connect to, and the Bridge can cover more distance than the WiFi devices. Hubs can be up to 2.5 miles apart, the Receiver can be up to 2 miles from the Hub, and the Bridge radios can be as much as 5 miles apart.

The Bridge also operates in the 5.8 GHz. band, while the Hub and Receiver operate in the 2.4 GHz. band.
