Article recommends holding until 2020 for 5G to spread more so & for innovations over the initial products this year.

You may want to hold off buying a 5G phone until 2020.  We know that 5G will officially launch in 2019, but the first 5G phones to hit the market this year could be quickly outshone by 5G devices launched towards the end of 2019 and into 2020. Smartphone chipset maker Qualcomm has announced its second generation 5G modem, the Snapdragon X55, which it claims is the world’s first capable of 7Gbps.  What does that mean for you? Even faster internet speeds, allowing you to download movies, apps, TV shows, games and music in seconds, although you’re unlikely to see that top-end 7Gbps speed instantly as networks continue to develop their 5G experience.
