Have you noticed some routers have 2 signals?

They are called SSID and each signal serves a purpose. One is for speed, and the other, for coverage. Not all devices can see both signals because the 5 Ghz signal is a newer technology, but all of them use the 2.4 Ghz signal.

The 2.4 Ghz technology has been used for years. Before its use for wireless internet it has been used for cordless phones, microphones, CB radios, microwaves, and Bluetooth devices, among others, which makes it the most used frequency. 2.4 Ghz reaches a long range, but it receives lots of inference.

 

The 5 Ghz frequency is better because it has not been used as much and is currently dedicated mostly for Wi-Fi internet, though its caveat is a limited range. 

A new technology called Wi-Fi 6 is set to launch this year (2019). Wi-Fi 6 uses both bands, 2.4ghz and 5ghz, and cramps more channels in each band, which allows for faster speed and an expanded range.

Wi-Fi 6 is supposed to be up to three times faster than what we are used to, which will allow us to get the most out of our internet connection. Wi-Fi 6 also comes with new security protocols, resulting in a more secure connection for users.
