What a difference a year makes, especially for 5G. The new mobile network tech, which seemed almost futuristic a year ago, is widely available today, especially in big cities where the 5G rollout has been prioritized. As such, the AT&T 5G network has expanded and covers more than 14,000 cities and towns throughout the U.S. (see our 5G coverage map for details). If you have 5G coverage, it's likely on a sub-6 network, which is more available right now. Sub-6 relies on lower frequencies to deliver a larger wireless network, but with a tradeoff in speed, which may be only marginally faster than 4G. Another 5G variant called mmWave (millimeter wave), differs in that the network's radio waves are much faster than sub-6 networks, offering multi-gigabit speeds at various points. It relies on frequencies that can travel short distances but cannot penetrate obstacles like walls or windows. Sub-6 frequencies travel further, sometimes a distance of miles, but the connections can't reach the same speeds as mmWave. AT&T's network is largely comprised of Sub-6. Depending on your location, the carrier's Sub-6 5G may be slower than 4G networks because AT&T doesn't have adequate spectrum to deploy to both networks simultaneously. In… Read full this story
