Everyone is talking about 5g, but do they really know what it is? More than four out of five Americans have no idea what 5G is, according to a new survey of 2,500 US consumers done exclusively by PCMag.com. Carriers are not doing a very good job at explaining 5g. Some already think they have it on their phones, but as of right now no phones have 5g. Also, only a few homes have 5g in four small cities.
