4G LTE:
The original idea was that it represented a "Long-Term Evolution" toward the 4G standard. What clever marketers figured out was that they could present it as something greater than that standard if they simply added "4G" before it. Hence, "4G LTE."
To qualify for true 4G, your wireless network has to be able to download at a minimum of 100 Mbps. Some carriers have dubbed this 4G LTE-A (Verizon), 5Ge (AT&T), or 4G LTE+ to separate it from 4G LTE.
5G:
To be considered true 5G, the standard has a minimum requirement of 1 Gbps with 1 millisecond of latency.
5G+, 5GUW, and 5GUC:
When connected to low-band frequencies, AT&T, Verizon, and T-Mobile devices display the standard 5G icon. The icon changes to 5G+ for AT&T, 5G UW (Ultra-Wideband) for Verizon, or 5G UC (Ultra-Capacity) for T-Mobile when connected to the mid-band or high-band spectrum. These will be the 5G networks closest to true 5G.
I just ran a speed test on my phone while it was displaying the standard 5G icon. Latency was 56ms (about 1/20 of 1 second), upload 1.08 Mbps, download 46.7Mbps. I have AT&T.
