Why does TestOut tell me 4G internet is capable of speeds up to 1Gbps?



I’m doing online courses, and a TestOut LabSim video I just watched was going over mobile internet connections. They claim 4G can reach speeds of 1Gbps, though I find that incredibly hard to believe as that would make my cell phone internet speed 20 times faster than my home computer’s. Is this some kind of laboratory conditions theoretical max or are they just wrong?

From the LTE Advanced Wikipedia page

“Three technologies from the LTE-Advanced tool-kit – carrier aggregation, 4×4 MIMO and 256QAM modulation in the downlink – if used together and with sufficient aggregated bandwidth, can deliver maximum peak downlink speeds approaching, or even exceeding, 1 Gbit/s. Such networks are often described as ‘Gigabit LTE networks’ mirroring a term that is also used in the fixed broadband industry”

To my more layperson understanding, that is something along the lines of combining multiple LTE connections into one effectively faster one.

According to the UN agency that makes the rules, [“4G”](https://www.itu.int/en/ITU-R/study-groups/rsg5/rwp5d/imt-adv/Pages/default.aspx) must support 1Gbps if you’re standing still and 100Mbps if you’re moving quickly (on that page, it’s listed in the box on the side). And yes, LTE-A technically can meet that requirement in laboratory conditions. In practice, you’re not going to get anywhere near 1Gpbs.
