10、 42892023 State of 5GThe Promise of 5GEach wireless generation delivered better service and new capabilities to consumers and businesses.The first wireless networks let us communicate on the go,but only by voice,and service was spotty.The advent of 2G brought digital technology to wireless,3G paved

11、the way for the initial mobile internet,and 4G enabled true mobile broadband,unleashing the app economy and inspiring other industries to harness the power of wireless.5G will be much faster than 4G,with speeds up to 100 x faster.5G is reducing latency,or the delay that occurs when data is transmitt

12、ed across distances.Low latency is especially important for machine-to-machine communications that require precise timing.5G is expected to be 5 times more responsive than 4G.5G technology will also be able to handle 100 times the number of connected devices,enabling dense deployments of connected d

22、G12132023 State of 5GDelivering Ahead of Schedule The United States has made remarkable achievements with 5G deployment.Compared to the launch of 4G,providers are delivering broader coverage at a faster pace,and consumers are adopting 5G devices more quickly.Across several network performance metric

23、s,5G is delivering ahead of schedule.While we are still in the early stages of what will be a decade-long 5G investment cycle,U.S.wireless providers have already built a strong 5G platform for innovation,job creation,and economic growth that will continue to grow in the years to come.DEPLOYMENT5G de

24、ployment is moving at a faster pace than 4G.The first 5G network achieved nationwide coverage twice as fast compared to 4G,5 and the three major providers were able to provide nationwide networks 1.5 times faster than with 4G.6 5G networks across the United States already cover over 325 million peop

25、le,giving us the worlds most available 5G networks.Ookla puts the United States as the world leader in availability,with over 54 percent of connections from 5G-capable handsets connecting to a 5G network most of the time.7 This puts us ahead of South Korea by almost 20 points,a truly remarkable feat

26、.8 Were at nearly double the 5G availability of China,which is at 27.3 percent.9This quick initial deployment underscores the wireless industrys commitment to global leadership,which only continues as networks expand and densify.As discussed further below,5G works best with a mix of different types

27、of spectrum,and operators do not yet have access to an optimal blend of frequencies.While the base-line initial platform of 5G has been quickly deployed at a wide scale,5G networks will need to keep getting better to meet Americas wireless needs.5G Availability in Select MarketsUnited States54%Cypru

30、rge-scale 5G deployment,the U.S.had 50 million people subscribed to 5G versus 38.6 million subscriptions two years after the first large-scale 4G launch.10 Looking at market penetration at the same two-year mark,almost 15 percent of Americans have subscribed to 5G,compared to about 12 percent two ye

31、ars after 4Gs first large-scale launch.11Today,over one in three American adults have an active 5G devicea quickly growing contingent:The number of 5G devices in the United States grew over 500 percent between 2020 and 2021 to 85 million.12 NETWORK PERFORMANCE5G is already showing marked improvement

32、 over earlier generations of wireless across several performance criteria.Wireless network speed(or data throughput)is one of the most important factors affecting user experience,especially for data-hungry applications like streaming video.Again compared to the 4G era,5G is bringing bigger improveme

33、nts faster than we saw before.Eighteen months after the launch of 4G,average download speeds were only about 3 times faster than the previous generation.Over a similar timeframe,5G speeds were more than 16 times faster than 4G speeds.That means 5Gs rate of speed increase is over 5 times faster than

34、4Gs.13 Speeds on 5G networks are now routinely over 100 Mbps,and continually getting faster.Latency is another important performance metric,measuring the time delay as information transfers across the network.Low latency is critical to having a responsive network,and for some applications,such as 5G

35、-enabled driverless cars,precision robotics,or high-quality augmented reality,it really matters.Here again,5G is already bringing measurable improvements in overall responsiveness.According to real-world Ookla measurements,only about 15 percent of 4G connections have a latency of under 20 millisecon

36、ds,whereas more than 80 percent of high-band 5G connections are faster than 20 ms.14 That makes for a roughly 5 times improvement over 4G latency,helping empower more real-time applications.Spectrum plays a critical role in determining 5G network performance.Electromagnetic spectrumthe invisible rad

37、io waves by which mobile data travels through the airhas different properties depending on its frequency and wavelength.5G works best when it has a mix of different types of spectrum to be able to optimize connectivity for different use cases.For policy discussions,spectrum can be broken down into l

38、ow,mid and high bands.Low-band spectrum(spectrum below 3 GHz)can cover wide areas with a single cell tower and can propagate well through foliage and around buildings.Low-band provides crucial foundational coverage.High-band spectrum(spectrum above 24 GHz)provides extremely high-speed connections by

39、 using what the industry calls mmWave technologyrelying on the tiny wavelengths of this high-frequency spectrum,measured in millimeters.While high-band spectrum provides great performance,it does not propagate very far and is easily blocked by obstructions.Mid-band spectrum(focused on spectrum betwe

40、en 3 and 8.5 GHz)provides a happy medium:it can leverage advances in technology to provide high capacity,and still provides relatively good coverage.Other nations have done a better job of making mid-band spectrum available for 5G services.Frequencies above 8.5 GHz,while still useful,are more simila

42、vesting an estimated$275 billion into network infrastructure to build out 5G and enhance network coverage,security,and capabilities.15 Fierce competition has driven nationwide providers to pour billions into designing and deploying networks they anticipate will best win over customers and enable new

43、 use cases.A record$35 billion was invested by providers in 2021,and since 2018,the year 5G launched,providers have already invested over$121 billion.16 To further contextualize this extraordinary investment,the United States is just 4 percent of the worlds population,but we invest 19 percent of the

44、 worlds total wireless capital.17 Looking at 5G investment on a per capita basis,in 2020,the U.S.wireless industry invested 4.5 times more than Chinese counterparts.18 5G investment has driven efforts to expand and densify networks to support innovative services.By the end of 2021,there were 418,887

45、 operational cell sites across the nation,and that doesnt account for all the new 5G base stations added to existing cell sites.19 Federal and state siting reforms encouraged the rapid deployment of 5G,with 62 percent of cell sites built from 2016 to 2021 coming after reforms were made.Operators als

46、o invest heavily in spectrumthe lifeblood of wireless networks.The Federal Communications Commission(FCC)auctions licenses that provide rights to use particular airwaves without interference from others.The wireless industry competes vigorously in these auctions to gain the resources needed to build

47、 ever-better performing networks.Over the years,these auctions have raised over$233 billion for the U.S.Treasury and policymakers priorities.20 In turn,this spectrum has supported deployments by national operators,regional carriers,and new entrants.Demand for licensed spectrum is growing rapidly:Abo
