The next advancement in cellular technology, 5G, is expected to be so fast that it's able to surpass the speed of wired internet now provided by cable companies.
Current 4G technology provides download speeds of about 1 gigabit per second. With 5G technology, download speeds are expected to increase to 20 gigabits per second, said Ellen M. Lord, the undersecretary of defense for acquisition and sustainment.
Lord spoke yesterday at the Atlantic Council here to discuss the Defense Department's efforts to advance 5G technology in the United States and to ensure that when 5G does make its debut, it's secure enough to transmit information between U.S. military personnel and its allies without being intercepted by potential adversaries.
U.S. and allies must take lead
That means the U.S. and its allies will need to take the lead in developing this next generation of telecommunications technology, she said.
"When we talk about 5G, everything is going to be moving over it, eventually," Lord said. "What we need to do is make sure how that information is moving, and how you can get at it, and how you can keep it secure."

Lord likened development of the 5G infrastructure and technology to that of a new home. She said new home owners certainly would want to know that whoever built their home, wired it for electricity, installed the communications systems, or installed the doors and windows hadn't also built in a way for them to sneak back into that house undetected after the new owners had moved in.
"That's where we are with 5G," Lord said. "If we are going to run our entire warfighting ecosystem though communications — which is where we are today — we need to make sure that when we send a critical message that others aren't hearing it. We need to be able to test that."
On the modern battlefield, and on the battlefield of the foreseeable future, communications is going to play a critical role, Lord said. Information must flow between mounted and dismounted soldiers, from ships at sea and from those under the sea, as well as to space and aircraft.
"In order to get relevant situational understanding, we are trading information back and forth all the time," she said. "What will happen is, if we do not embrace 5G, and we are just getting going in 4G in a lot of areas, we are going to have a latency or a delay in those conversations that could render everything we have as ineffective."
U.S. industry and partners must provide advancements
Advancements in 5G must come from U.S. industry and U.S. partners to be trustworthy and reliable, Lord said.
The Pentagon, headquarters of the US Department of Defense.
"Right now there is quite an intensive dialogue going on to understand where in Europe we might partner," Lord said. "And there has been an enormous amount of discussion about the threat that we see by the Chinese — theft of intellectual property — coming into our networks. We have to collectively decide how we are technically going to secure our networks — how we legislatively have to have protection."
Lord said a whole-of-government approach is needed to get a handle on 5G. The State, Treasury and Commerce departments and the National Security Council should be involved along with DOD, she said.
"I think you are going to see a huge call to action this year to come together with really what is almost a national industrial policy for 5G, because the stakes are high," Lord added. "5G from a technology point of view is a huge opportunity, but it's a huge threat.
"If we don't embrace it and apply it towards our goals, we could be overcome quickly with technical overmatch," she continued. "And we can't allow that to happen. ... We have a warfighting imperative. If we cannot communicate as quickly, or quicker than our adversaries, if we cannot have situational understanding as to what is happening on the battlefield, then we are going to be in a position where our national security is threatened."
