In contrast, a broadband signal is a signal which does not occupy the lowest range, but instead a higher range, 1MHz to 3MHz, for example. A wire may have only one baseband signal, but it may hold any number of broadband signals, because they can occur anywhere in the spectrum.
Single band routers transmit signals on a 2.4 GHz band. A dual band router transmits on a 5 GHz band and a 2.4 GHz band. Because some Wi-Fi equipment only supports the slower band, the router transmits data at a slower speed for those devices. Many cell phones use dual band transmitters for faster access and better roaming service. How Dual Band Routers Function
