According to the study, in 2035, when 5G’s full economic benefit should be realized across the globe, a broad range of industries – from retail to education, transportation to entertainment, and everything in between – could produce up to $12.3 trillion worth of goods and services enabled by 5G. The 5G value chain itself is seen as generating up to $3.5 trillion in revenue in 2035, supporting as many as 22 million jobs. Over time, 5G will boost real global GDP growth by $3 trillion dollars cumulatively from 2020 to 2035, roughly the equivalent of adding an economy the size of India to the world in today’s dollars.
