The long-anticipated promise of 5G has now largely materialized, with communication service providers worldwide achieving widespread deployment of 5G networks. Although 4G networks continue to meet the internet needs of many users, the adoption of 5G technology is accelerating rapidly. Nations striving to preserve their competitive advantage in the global economy have extensively implemented 5G infrastructure, ensuring its availability to a substantial portion of their populations. This next-generation technology fulfills its commitments, delivering an expanded spectrum for wireless communication, consistent gigabit-plus connection speeds, and significantly reduced latency compared to 4G. The improved reliability and adaptability of 5G are facilitating innovative applications across diverse sectors, including smart cities and industrial Internet of Things (IoT). As 5G coverage continues to broaden, focus is increasingly shifting toward the development and potential of 6G technology, with research advancing and standardization efforts commencing in 2025, targeting commercial deployment around 2030.

The advent of 5G networks offers transformative opportunities for both businesses and consumers, driven by enhanced speed and connectivity. This wireless technology is poised to accelerate the adoption of advanced applications such as self-driving vehicles, augmented reality (AR), extended reality (XR), virtual reality (VR), and a growing array of IoT devices. Recent projections reaffirm that 5G could generate 22.3 million jobs and contribute USD 13.2 trillion to the global economy by 2035, underscoring its profound economic potential. The demand for 5G networks is surging, fueled by the rapid proliferation of IoT devices and advanced mobile broadband technology. Global 5G connections have seen remarkable growth, reaching 1.76 billion in 2023 and projected to climb to 2 billion by the end of 2025, a significant increase from the 429 million recorded in Q2 of an earlier year, which marked a 41% rise from 305 million in Q1.

5G networks were operational in 2,497 cities across 92 countries by 2023, a notable expansion from the 1,336 cities and 61 countries reported since January 2020. This growth, likely even higher as of April 2025, reflects robust deployment efforts despite global challenges such as the pandemic. The majority of these deployments are concentrated in Asia, where subscriber demand for high-speed and reliable connectivity drives network expansion. China and the United States remain at the forefront of this progress, leading in bandwidth expansion and 5G rollout. China excels in connection numbers, while the USA has surpassed others in the number of cities covered, highlighting their strategic focus on maintaining technological leadership.

Here Are The Top Ten Countries With The Largest 5g Network In The World

1.    Vietnam

Vietnam is among the first countries to adopt 5G deployment for their commercialization plan. The growth has been such that Vietnam’s 5G market is expected to grow steadily, with the market valued at USD 822 million in 2023 and projected to reach USD 2.1 billion by 2029, growing at a CAGR of 17.1%. Vietnam has long stated its plan to provide efficient 5G coverage by 2030, aiming to offer high-speed internet connections at low cost, according to the Ministry of Information and Communication.

Vietnam has the fastest-growing digital economy in Southeast Asia, which hit $23 billion in value in 2022 and is purposefully set to achieve over $50 billion by 2025, largely driven by a thriving e-commerce sector. This growth is supported by increased efforts to drive digitalization, with the digital economy’s gross merchandise value (GMV) expected to grow by 31% from 2022 to 2025. In 2022, the country planned to reduce the number of 2G subscribers from 24 million to 5-7 million to free up more bandwidth for 3G, 4G, and 5G networks. By 2024, the Ministry of Information and Communications (MIC) is expected to stop extending the licenses for 2G and 3G, aiming to completely phase out 2G by September 2045. Their 2025 objective is to popularize 4G/5G network services and smartphones..

2.    United States

5G coverage is expected to reach 75% of the US population, by 2025, which is up from 13% in 2020, with the expansion of the use of the mid-band spectrum in urban and suburban areas. Major mobile operators such as AT&T, T-Mobile, and Verizon are focused on deploying mid-band 5G through 2021 and 2022. While AT&T and Verizon have been strengthening their high band millimeter wave and low 5G offering, a new entrant like Dish is planning to commence its commercial 5G services from 2022. According to Ericsson report, around 195 million 5G subscriptions can be expected by 2026, and the technology is anticipated to occupy 71.5% of the entire US mobile market by 2029. The economic benefits will be shared across rural communities and minority groups in urban areas to bridge the digital gap to ensure access. As per the Cellular Telecommunication Industry Association (CTIA) estimates, the rapid growth with the expansion of 5G technology could drive USD275 billion in investment and lead to USD500 billion in economic growth. In addition, FCC has also auctioned or planned to auction several mid-band spectrum bands such as 2.5GHz, 3.5 GHz, and 3.7-4.2 GHz because of their ideal nature of the ability to carry heavy data flow, while traveling significant distances.

3.    South Korea

5G market of South Korea falls among the most advanced and competitive market in the world. The country was the first to launch commercial 5G services in 2019 and has since effectively penetrated the market. South Korea, one of the early adopters of 5G in 2018, continues to set benchmarks with high-speed and low latency. SK Telecom, LG Uplus, and KT, South Korea’s 3 mobile operators, improved their 5G speed and experience score in 2022. Besides, immense support from the South Korean government to expand nationwide 5G coverage to 70% by 2025 is expected to accelerate the South Korea 5G market. 

With the country providing the fastest average internet connection in the world, a quarter of South Korean mobile users have already subscribed to 5G. Top South Korean telecom operators plan to commercialize new 5G technologies such as millimetre-wave 5G, standalone versions of 5G networks, etc. while making a net investment of USD22 billion through 2022. Besides, South Korea’s Ministry of Science and ICT has planned to make available a total of 600 megahertz in the 28 GHz band and 100 MHz in the 4.7 GHz band throughout the country.

4.    United Kingdom

All 5G Networks Are Not Equal

After years of successful deployment, 5G is now gaining significant momentum. Telecom operators around the world have invested significantly to offer the fastest, most reliable, and most extensive 5G coverage. For future reference, the four major mobile carriers in the United States are building their 5G networks in different ways. AT&T has both a limited mmWave network and a more broadly available low-band network. The same goes for T-Mobile, which just switched on its low-band network around the nation to go along with a handful of higher-end service areas. Finally, Sprint operates on the mid-band for now, while Verizon has focused on mmWave technology.

Current 5G networks mostly utilize NSA EN-DC (TDD in n78 and FDD in n28) and DSS (FDD in n28, n1 and n3 bands. However, the real 5G and 5G+ is coming. Reliability, response times, and interactivity will be boosted. However, SA 5G network deployment may take some months to actually take off on a large scale.
