There are now two standards for 5G. One is 5G Non-standalone (NSA). The current networks around the world use this standard in which 5G and 4G technology can be combined. The other is 5G Standalone which of course ensures lower latency.

In 5G NSA, data uploads can use existing 4GLTE advanced network and radio, providing speeds comparable to a 4G phone. Most consumers download more data for which they need higher speeds ( rather than upload).
