Mobile Growth Driving Need for Advanced Wireless Networks
With more than 5 billion mobile subscriptions globally as of 2020, wireless networks have become the primary means of internet access for billions of people worldwide. This tremendous growth in mobile devices and usage has driven immense demand for advanced wireless infrastructure that can support higher data speeds, broader coverage areas, and more connected devices overall. Mobile data traffic alone has grown over 1000-fold in the past decade and is expected to continue increasing exponentially into the future. With new technologies like 5G, artificial intelligence, IoT, AR/VR on the horizon—wireless networks must evolve to keep pace. This growing reliance on mobile connectivity means investing in innovative wireless infrastructure is critical for economies, communities and connecting the unconnected around the world.
Building Out Cell Towers and Small Cells
One of the primary components of Wireless Infrastructure is cellular towers or macro cell sites. Traditional "macro" cell towers are large structures, usually ranging from 30-200 feet high, that provide connectivity over wide metropolitan or rural areas. As mobile data usage explodes, wireless carriers are continuously deploying new macro cell towers and upgrading existing infrastructure to support 4G/LTE and future 5G networks. Smaller "small cell" sites are also gaining popularity as a complementary solution for capacity in dense urban environments. Small cells have a shorter range but are ideal for places like busy streets, stadiums and airports. They are typically installed on existing structures like light poles, buildings and surveillance cameras without obstructing pedestrian traffic. Both macro towers and small cells employ technologies like carrier aggregation, massive MIMO and beamforming to maximize spectral efficiency and coverage from each site.
Establishing Nationwide Fiber Backbones
Connecting all the individual cell sites together into cohesive wireless networks requires nationwide fiber optic backbones. Laying extensive new fiber lines is a monumental undertaking made increasingly important as mobile data usage climbs. High-capacity fiber networks transport massive amounts of data traffic between cell towers and network core facilities. They enable seamless roaming, support for multimedia services, and enable network functions like carrier WiFi offload. Countries are making major investments in fiber deployment through public/private partnerships to build 5G-ready fixed broadband networks across cities and remote regions. Laying rural fiber helps extend connectivity to underserved communities. It is a long-term infrastructure project critical for linking together the growing number of cell towers, small cells and wireless technologies of the future.
Enhancing Pole and Duct Access Rights
Easing the deployment of small cells and fiber backbones requires streamlining access to existing infrastructure like utility poles and underground conduits. Utility poles currently carry power and telecom cables but accessing them can involve complex negotiations between multiple stakeholders. Regulations are evolving to promote pole attachment agreements that simplify the installation process and speed up deployment timelines. Expedited procedures allow wireless operators and contractors to attach equipment quickly while maintaining safety. Secure underground conduits are likewise important for fiber deployment. Gaining efficient access to duct space through “dig once” policies can significantly reduce deployment costs when new conduit sections are added during public works projects. Joint use of existing right of ways helps boost the business case for investment in distributed wireless and fiber infrastructure.
Innovating with Satellite Connectivity
While terrestrially-based wireless infrastructure remains core to global connectivity, complementary satellite solutions are playing an increasingly vital role—especially for reaching remote, rural and challenging topographies. Satellite internet services enable connectivity in areas beyond the economic reach of fiber or cellular networks. Low Earth Orbit (LEO) constellations with thousands of small satellites in low-altitude orbits promise broadband connectivity at lower latencies. They compete directly with traditional satellite and terrestrial offerings through always-on, high-speed access. Satellite backhaul also supports cellular tower connectivity in areas lacking fiber infrastructure. New hybrid satellite-terrestrial systems employ both approaches for capacity where needed. Continued innovation in space-based technologies ensures all regions and communities can benefit from high-quality global connectivity.
Securing Critical Infrastructure
With wireless networks integrated into every facet of modern life and commerce, cybersecurity is paramount. Mobile operators employ multi-layered approaches to safeguard infrastructure including firewalls, encryption, authentication and monitoring systems. As networks transition to virtualized architectures like 5G, security must be embedded from the start. Careful planning and oversight helps mitigate vulnerabilities from supply chain, maintenance access and natural disasters. Security also encompasses physical aspects like protecting cellular towers, small cells and network facilities. This reduces theft of materials, vandalism and ensures continuous service availability. Regulatory policies promote sharing best practices between public and private stakeholders. Coordinated efforts at all levels helps strengthen the resilience of critical wireless infrastructure against evolving cyber and physical threats.
Preparing for Next-Gen Technologies
While infrastructure buildouts focus on current LTE and early 5G deployments, attention is also turning to future-proof networks capable of enabling technologies like artificial intelligence, augmented reality, self-driving vehicles and smart cities. This includes migrating to open interfaces, virtualization and network slicing capabilities in 5G standalone core networks. It also involves preparing wireline networks for exponential data capacity growth through multi-terabit fiber deployments. Trials focus on applications of promising innovations like Terahertz wireless, integrated access backhaul (IAB) and satellite-5G integration. Harmonizing global spectrum bands ensures optimal use of wireless resources. Coordinated R&D efforts help deliver reliable, high-capacity wireless and fiber infrastructure sustain economic growth fueled by emerging technologies for decades to come.
