* [[Timeline of 5G]]: I added some section headers and made a slight update to the sample questions. A few further requests:

** Add Wikipedia Views data: across devices at https://wikipediaviews.org/displayviewsformultiplemonths.php?page=5G&allmonths=allmonths&language=en&drilldown=human and maybe also a comparison of generations: <pre>https://wikipediaviews.org/displayviewsformultiplemonths.php?pages[0]=1G&pages[1]=2G&pages[2]=3G&pages[3]=4G&pages[4]=5G&allmonths=allmonths-api&language=en&drilldown=human</pre> (look at the chart that does not break down by device; did the chart July 2015 onward because some of the data before that is missing for some of the pages and we can't fill that in)
