Sometimes language changes slowly and inadvertently. The meaning of words can change over time as language evolves. That’s how many semantic environments become polluted: little by little. But sometimes change happens abruptly and purposefully. This past weekend, AT&T gave us an excellent example of how to pollute a semantic environment in one blow.

Today’s mobile phone networks work on what’s known as 4G technology. It’s a standard that’s widely adopted by the mobile communications industry. When your smartphone connects to a 4G network, you see a little icon on your phone’s screen that says either 4G or LTE. These 4G networks are plenty fast for most uses today.

However, the industry is working on the next generation network technology called — you guessed it — 5G. The first 5G devices are already appearing on the market. That said, widespread rollout won’t be immediate: the new technology requires new hardware on phones, changes to cell towers, and a host of other changes. It’ll likely be a couple of years before the new standard becomes mainstream.

Despite these technical hurdles, last weekend AT&T started issuing updates to some Android phones in their network that change the network label to 5G. Nothing else is different about these devices; their hardware is still the same and they still connect using the same network technology. So what’s the reason for the change? AT&T has decided to label some advanced current-generation technologies “5G E.” When the real 5G comes around, they’ll call that “5G+.”

This seems like an effort to make the AT&T network look more advanced than those of its competitors. The result, of course, is that this change confuses what 5G means. It erodes the usefulness of the term; afterward, it’ll be harder for nontechnical AT&T customers to know what technology they’re using. It’s a bold example of how to co-opt language at the expense of clarity and understanding.
