The next generation of wireless technology, 5G, could be a huge deal. The speed and the number of devices that can be connected could spawn new businesses we haven't even thought of yet. Last year chipmaker Qualcomm and tech research firm IHS Technology put out a report that said 5G could enable $12 trillion in economic output across the world by 2035 and add some 22 million jobs. The report compared 5G to electricity. Compare that to 4G, which, just in the U.S., contributed about half a trillion dollars to the economy in 2016.
