Many People are still confused about 5GHz Wi-Fi and 5G. This is the best descriptions of the differences between the two that I have seen!

” Despite the similarity in title, they are not the same. 5GHz refers to a frequency band currently used in Wi-Fi networks. 5G stands for the 5th generation standard for broadband cellular networking technology. 5GHz Wi-Fi is operating in a higher frequency band than Wi-Fi in the 2.4 GHz band (earlier Wi-Fi technology, which shares that spectrum band with other wireless technologies like Bluetooth), and offers more bandwidth, translating to faster speeds and more capacity. Note, with Wi-Fi 6E, there is also the 6GHz frequency band with even more bandwidth. Wi-Fi on 5GHz and 6GHz are great for high-bandwidth and low-latency activities such as streaming and gaming. 5G cellular network is the newest generation of broadband cellular network services. 5G is used to upload and download information from your smartphone when not connected to a Wi-Fi network.”
