5G and Next-Generation Wireless Networks Likely to Reshape Global Digital Mobility and Geopolitical Competition

Emerging economies and technology hubs are rapidly adopting 5G to drive economic growth and attract investment. China has been a key player in Africa's 5G development with its state-owned enterprises building infrastructure in several countries. Two of Brazil’s largest telecommunications providers are investing in 5G networks to attract foreign investment. A leading South African mobile operator and cellular network is deploying 5G infrastructure and smart city solutions in partnership with local technology providers to support applications in financial technology (fintech) and other sectors. 

In May, an Indian academic institution and a Japanese semiconductor company tested advanced Beyond 5G and 6G technologies to demonstrate how data can be transmitted reliably at high speed and connected to mobile systems for various applications, such as autonomous vehicles and satellite-ready Internet of Things (IoT). 

However, the technical evolution of wireless systems cannot be separated from the geopolitical forces shaping their development and deployment. The strategic competition between the US, China, and other actors has escalated in recent years. Trade restrictions and regulatory fragmentation also influence which network equipment can be used, where it can be deployed, how data is secured, and who controls critical infrastructure. 

Despite these challenges, emerging economies and technology hubs provide opportunities for international businesses and travelers. For businesses, these regions include access to expanding markets and a cost-effective workforce. For travelers, these regions often include advanced digital infrastructure and greater connectivity, which makes business and leisure travel more efficient and convenient. 

Emerging economies and technology hubs also face operational challenges. The primary challenges include, but are not limited to, gaps in infrastructure that can limit connectivity, slow implementation of new systems, different governance norms surrounding privacy, and the role of government intervention in the private sector. 

The next three years will likely bring growing nationalization of digital infrastructure and increased regulation of cross-border data flows. Governments will likely implement stricter compliance regimes for foreign tech firms operating in sensitive sectors, especially in AI and communications. Wireless network access may also become more conditional and be connected to security partnerships or trade negotiations. 

To mitigate risk, organizations should treat network access as a strategic asset and a potential risk. Businesses should identify critical operations that depend on wireless networks and assess their operational exposure to geopolitical frictions. Companies must prioritize multi-region redundancy in cloud services and network access, especially concerning supply chains or operations in sensitive regions. 

International travelers should plan for secure network access by following local laws on encryption, data storage, device use, and VPN regulations. Visitors should rely on trusted roaming services rather than local SIM cards in high-risk areas and limit the number of connected devices carried, including laptops and emerging augmented or virtual reality equipment. Individuals should regularly update all devices with region-specific threat information and use device-level firewalls or endpoint security software to protect their personal and work-related systems.
