The mobile industry has seen tremendous growth and transformation over the past few decades, driven by advancements in technology and infrastructure.
From the first generation of cellular networks that supported basic voice transmissions to 5G, which promises ultra-fast, reliable mobile connectivity, the evolution of mobile infrastructure has been pivotal in shaping modern communication, with key developments including the deployment of mobile telecommunications to overcome poor fixed-line infrastructure in developing regions, the expansion of mobile money services and the ongoing rollout of 5G networks globally.
Here, Mobile Magazine explores the Top 10 infrastructure developments in the mobile industry.
10. Digital Infrastructure Initiatives
Governments and private sectors are investing in digital infrastructure initiatives to bridge the digital divide and ensure equitable access to digital services. These initiatives aim to expand broadband access to rural and underserved communities, providing the necessary infrastructure for economic development, education, healthcare, and other essential services. In the United States, the Broadband Equity, Access and Deployment (BEAD) program is a significant initiative aimed at expanding broadband access. Meanwhile, the European Union's Connecting Europe Facility (CEF) supports the development of high-speed broadband networks across member states.
9. Hyperscale Data Centres
The construction of hyperscale data centres is supporting the growing data storage and processing needs of mobile networks. Hyperscale data centres are large-scale facilities designed to efficiently handle vast amounts of data, providing the necessary infrastructure for cloud services, big data analytics, and other data-intensive applications. These data centres are characterised by their ability to scale out quickly and support high levels of redundancy and fault tolerance. Companies like Amazon Web Services (AWS) and Microsoft Azure are leading providers of hyperscale data centers.
8. Network Virtualisation and SDN
Network virtualisation and Software-Defined Networking (SDN) are transforming mobile networks by decoupling hardware from software, allowing for more flexible and efficient network management. Network virtualisation involves creating virtual versions of network resources, such as servers and storage, while SDN separates the control plane from the data plane, enabling centralised network management. These technologies offer several benefits, including improved network agility, reduced operational costs, and enhanced scalability. Companies like Cisco and VMware are leading the development and deployment of network virtualisation and SDN solutions.
7. Satellite Internet Services
Satellite internet services are being developed to provide connectivity in remote and underserved areas which traditional terrestrial networks often struggle to reach due to geographical and economic challenges. Satellite internet offers a viable solution by delivering high-speed connectivity from space, with companies such as SpaceX with its Starlink project and OneWeb continuing to lead the development of satellite internet services.
6. IoT Network Development
The development of IoT-specific networks, such as LoRaWAN and NB-IoT, is enabling the proliferation of connected devices. These networks are designed to support low-power, wide-area applications, crucial for smart city initiatives, industrial IoT, and other use cases that require long battery life and extensive coverage. LoRaWAN (Long Range Wide Area Network), developed by Semtech, and NB-IoT (Narrowband IoT), standardised by 3GPP, are two leading technologies in this space.
5. Deployment of Small Cells and DAS
To enhance network coverage and capacity, especially in urban areas, telecom operators are deploying small cells and Distributed Antenna Systems (DAS). Small cells are low-power, short-range wireless transmission systems that cover small geographical areas, such as street corners or buildings. DAS, on the other hand, is a network of spatially separated antenna nodes connected to a common source, providing wireless service within a specific area. These technologies help to offload traffic from macro cells and improve indoor coverage, addressing the challenges of network congestion and poor signal quality in densely populated areas.
4. Expansion of Fibre Optic Networks
Fibre optic networks are being expanded to support the increasing data demands of mobile networks. Fibre optics use light to transmit data at high speeds over long distances, making them ideal for backhauling data from cell towers to core networks. This infrastructure is essential for ensuring high-speed connectivity and supporting the growing number of connected devices. Companies like Google Fiber and AT&T Fiber have led the expansion of fibre optic networks, with AT&T Fiber providing high-speed internet services across multiple cities in the US.
3. Edge Computing Integration
Edge computing is being integrated into mobile networks to reduce latency and improve the performance of data-intensive applications. Unlike traditional cloud computing, which relies on centralised data centres, edge computing processes data closer to where it is generated. This is particularly important for applications that require real-time processing, such as augmented reality (AR), virtual reality (VR), autonomous driving and industrial automation. Companies like Nokia and Ericsson are at the forefront of edge computing integration in mobile networks.
2. Mobile Money Services in Sub-Saharan Africa
The deployment of mobile money services has revolutionised financial inclusion in regions with limited access to traditional banking. In Sub-Saharan Africa, mobile money has become a lifeline for millions of people. M-Pesa, launched by Safaricom in Kenya in 2007, is one of the most successful mobile money services globally, allowing users to deposit, withdraw, transfer money, and pay for goods and services using their mobile phones.
Other countries in the region, such as Tanzania, Uganda, and Ghana, have also seen the proliferation of mobile money services. Companies like MTN and Airtel have expanded their mobile money offerings, reaching millions of users.
1: 5G Rollout
The global rollout of 5G networks represents a significant leap in mobile infrastructure, offering faster speeds, lower latency, and greater capacity than previous generations. This technology supports a wide range of new applications, including IoT, autonomous vehicles and smart cities. Telecom giants like Verizon, AT&T and Huawei have been at the forefront of deploying 5G infrastructure. Verizon’s 5G Ultra Wideband network promises speeds up to 10 times faster than 4G LTE, while Huawei has been a key player in 5G deployments, especially in Asia and Europe. The adoption of 5G is expected to drive economic growth by enabling new business models and services, from enhanced mobile broadband to mission-critical communications and massive IoT. As countries continue to race to build and expand their 5G networks, the competition is also fostering innovation in related fields such as network security, spectrum management, and infrastructure sharing.
