And because of the way current 5G phones work, it often reduces performance."ĪT&T's 4G network benefits from the aggregation of channels from different frequencies. The counterintuitive result doesn't reveal much about the actual differences between 4G and 5G technology. Instead, it's reflective of how AT&T has used its spectrum to deploy 5G so far. As PCMag explained, "AT&T's 5G slices off a narrow bit of the old 850MHz cellular band and assigns it to 5G, to give phones a valid 5G icon without increasing performance. Instead, the disappointing result on PCMag's test has to do with how today's 5G phones work and with how AT&T allocates spectrum. Of course, AT&T 5G should be faster than 4G in the long run-this isn't another case of AT&T misleadingly labeling its 4G network as a type of 5G. PCMag concluded that "AT&T 5G right now appears to be essentially worthless," though AT&T's average download speed of 103.1Mbps was nearly as good as Verizon's thanks to a strong 4G performance. In PCMag's annual mobile-network testing, released today, 5G phones connected to AT&T got slower speeds than 4G phones in 21 out of 22 cities.
