The global race for 5G

Fight #1: The race to get 5G networks up and running.

• It's a three-way game right now among the U.S., China, and South Korea.
• Different studies predict different winners depending on what they measure —first to launch, first to achieve broad coverage, and so on.
• The U.S. is set to have initial 5G smartphone service next year with some very early commercial launches for mobile broadband this year.
• While the U.S. may be technically first with 5G in a few places, China is spending significantly more and will likely be first with 5G en masse.
• Some European carriers have been slower to move.

Fight #2: The competition over whose technology will power the networks.

• U.S. security concerns about Chinese equipment have loomed large, and Huawei is one of the major suppliers.
• As it has in the past, the U.S. won't allow Huawei to supply gear to major U.S. telecom firms, favoring European players Ericsson and Nokia (as well as Korea's Samsung).
• These concerns that prompted some U.S. officials to ponder earlier this year whether the country needed to nationalize the 5G effort, though that idea was flawed and faded fast.
• Worries about Chinese influence over 5G is a big reason why the Trump administration blocked Broadcom's attempt to purchase Qualcomm.

Be smart: The U.S. has no major cellular network equipment makers. Chipmaker Qualcomm is the biggest American player in the underlying 5G technology.

What they're saying: "I don't want the United States to win just so we can wave the flag saying we're number one," FCC Chairman Ajit Pai told Axios. Past winners of network races have "reaped a disproportionate amount of the benefits for their citizens."

• A study commissioned by the cell phone trade group CTIA estimated that U.S. companies won $125 billion in revenue by leading in 4G.
