President Donald Trump on Thursday brought renewed national attention to what has emerged as one of the most hotly debated technological and geopolitical challenges — the race to build a next-generation 5G wireless internet network.

The president used his Twitter account to broadcast the need for American companies to “step up their efforts” in establishing the 5G network “or get left behind.” 5G wireless networks are expected to offer superior connectivity and data speeds, paving the way for advanced technologies such as self-driving cars.

Trump also encouraged the development of 6G technology, which would conceivably offer even greater technological capabilities but remains almost entirely theoretical.
