ELI5: What is the difference between 3G, 4G, and 4G LTE?
gpt
That's gonna depend on what part of the world you're in. 2G, 3G and 4G relate to specification of each wireless standard for GSM technology. They indicate generations "G" of the wireless standard. 2G was essential EDGE data and 3G included HSPA and HSUPA, and so forth. However in the USA some carriers, think it was T-Mobile, started marketing 3G HSUPA as 4G for marketing reasons... So when they started rolling out actual 4G technology they had to call it something new... That's where terms like 4G LTE come from.
