Summary:
Since the first mobile phones were made available in the 1980s, telecommunication providers
have been investing in mobile networks to expand coverage, improve services, and attract more
users. First-generation networks supported mobile voice calls but were limited in coverage and
capacity. To address those limitations, providers developed and deployed second-generation (2G)
mobile networks, then third-generation (3G), and fourth-generation (4G) networks. Each
generation offered improved speeds, greater capacity, and new features and services.
In 2018, telecommunication providers began deploying fifth-generation (5G) networks to meet
growing demands for data from consumer and industrial users. 5G networks are expected to
enable providers to expand consumer services (e.g., video streaming, virtual reality applications),
support the growing number of connected devices (e.g., medical devices, smart homes, Internet
of Things), support new industrial uses (e.g., industrial sensors, industrial monitoring systems), perform advanced data
analytics, and enable the use of advanced technologies (e.g., smart city applications, autonomous vehicles).
5G is expected to yield significant economic benefits. Market analysts estimate that in the United States, 5G could create up
to 3 million new jobs and add $500 billion to the nation’s gross domestic product (GDP). Globally, analysts estimate that 5G
technologies could generate $12.3 trillion in sales activity across multiple industries and support 22 million jobs by 2035.
Experience has shown that companies first to market with new products can capture the bulk of the revenues, yielding longterm
benefits for those companies and significant economic gains for the countries where those companies are located.
Hence, technology companies around the world are racing to develop 5G products, and some countries (i.e., central
governments) are acting in support of 5G deployment. This competition to develop 5G products and capture the global 5G
market is often called the “race to 5G.”
In the race to 5G, the United States is one of the leaders, along with China and South Korea. Each country has adopted a
different strategy to lead in 5G technology development and deployment. China’s central government is supporting the
deployment of 5G infrastructure in China. China has a national plan to deploy 5G domestically, capture the revenues from its
domestic market, improve its industrial systems, and become a leading supplier of telecommunications equipment to the
world. In South Korea, the central government is working with telecommunications providers to deploy 5G. South Korea
plans to be the first country to deploy 5G nationwide, and to use the technology to improve its industrial systems. In the
United States, private industry is leading 5G deployment. U.S. providers, competing against each other, have conducted 5G
trials in several cities and were the first in the world to offer 5G services commercially. The U.S. government has supported
5G deployment, making spectrum available for 5G use and streamlining processes related to the siting of 5G equipment (e.g.,
small cells).
While each country has taken a different approach to capturing the 5G market, there are factors that drive the timeline for all
deployments, including international decisions on standards and spectrum. In the United States, 5G deployment may also be
affected by the lengthy spectrum allocation process, resistance from local governments to federal small cell siting rules, and
limitations on trade that may affect availability of equipment.
The 116th Congress may monitor the progress of 5G deployment in the United States and the U.S. position in the race to 5G.
Congress may consider policies that may affect 5G deployment, including policies related to spectrum allocation, trade
restrictions, and local concerns with 5G deployment. Policies that support 5G deployment while also protecting national and
local interests could provide significant consumer benefits, help to modernize industries, give U.S. companies an advantage
in the global economy, and yield long-term economic gains for the United States. In developing policies, Members may
consider the economic and consumer benefits of 5G technologies, as well as other interests, such as the need to preserve
spectrum for other users and uses, the protection of national security and intellectual property when trading, the privacy and
security of 5G devices and systems, and the respect of local authorities and concerns during 5G deployment.
