5G, the global standard as set by the 3GPP aka the real 5G, is expected to launch in 2020. Until then, carriers like AT&T are pre-building their 5G networks and in the interim calling their pre-5G services as 5Ge. Although it is technically LTE-advanced, it's peak speed does get into the low end of 5G territory. So it is 5G-ish.
