5G network architecture and technical specifications
At its core, 5G represents a fundamental shift in network architecture. Unlike its predecessors, 5G is designed to be a unified platform that can support a diverse range of services and applications. This new network infrastructure is built on three key pillars: enhanced Mobile Broadband (eMBB), Ultra-Reliable Low-Latency Communication (URLLC), and massive Machine-Type Communications (mMTC).
The technical specifications of 5G are truly impressive. With peak data rates of up to 20 Gbps and average user speeds of 100+ Mbps, 5G outperforms 4G by orders of magnitude. The network boasts ultra-low latency of just 1 millisecond, a significant improvement over 4G’s 20-30 milliseconds. This near-instantaneous responsiveness is crucial for applications requiring real-time feedback, such as autonomous vehicles and remote surgery.
Furthermore, 5G networks can support up to one million connected devices per square kilometre, a tenfold increase compared to 4G. This massive connectivity is essential for the proliferation of Internet of Things (IoT) devices and smart city infrastructure. The network also utilises advanced technologies like massive MIMO (Multiple-Input Multiple-Output) and beamforming to improve spectral efficiency and coverage.
Enhanced mobile broadband (eMBB) applications
Enhanced Mobile Broadband is perhaps the most immediately noticeable aspect of 5G for consumers. It promises to deliver significantly faster data speeds and more reliable connections, enabling a host of new applications and improving existing ones.
