Dual band is a computing term that refers to the operational capacity of the different bands. In telephony, it is known as roaming, which is intended to allow the same telephone service to be combined outside the area where the service is usually used. If a person wants to access the internet from the comfort of their home or in their business, they must have a wireless router, this will allow the transmission of the internet signal to various devices, that is why when buying a router you should opt for the dual band one, as this will provide you with better communication performance, it is much faster, especially in those tasks that require high demand, such as sending videos and sharing files within the network.
A dual band router (for example 2.4- and 5-GHz) gives the user the possibility to divide the broadband tasks, for example in the transmission of high definition movies. Users have the benefit of being able to surf the internet with an optimal level in the 2.4-GHz band, meanwhile they can transfer multimedia content simultaneously in the 5-GHz band, that is, the power to transmit in the band of the 5-GHz (which is less congested) could achieve a high speed in the sharing of several channels, thus reducing all the interruptions and noise that could spoil the efficiency of the wireless network.
