5G vs 4G: Key Differences

Speed: One of the most significant differences between 5G and 4G is speed. 5G networks are expected to offer peak data rates of up to 20 Gbps, which is up to 100 times faster than the peak speeds offered by 4G LTE networks. This means that users can download high-definition movies in seconds, enjoy smoother video streaming, and experience virtually no buffering during online gaming.
Latency: Latency refers to the time it takes for data to travel from one point to another within a network. With 5G, latency is expected to be reduced to as low as 1 millisecond, compared to around 30–50 milliseconds in 4G networks. This ultra-low latency enables near-real-time communication, which is crucial for applications like remote surgery, autonomous vehicles, and real-time AR/VR experiences.
Bandwidth: 5G networks offer significantly greater bandwidth than 4G, enabling them to support more simultaneous connections and handle massive amounts of data. This increased capacity is essential for accommodating the growing number of connected devices and ensuring reliable, high-quality connectivity even in densely populated areas or during peak usage times.
Network efficiency: 5G networks are designed to be more energy-efficient and resourceful than their 4G counterparts. Advanced technologies like network slicing and dynamic spectrum sharing allow 5G networks to optimize resource allocation, ensuring that each user and application receives the necessary resources without wasting valuable network capacity.

The 5G network architecture

Network layers: The 5G network architecture consists of three primary layers: the access network, the transport network, and the core network. The access network connects devices to the network via small cells and other wireless infrastructure. The transport network is responsible for carrying data between the access network and the core network, often using high-capacity fiber-optic connections. Finally, the core network manages overall network functions, including authentication, billing, and quality of service.
Core network enhancements: 5G introduces several enhancements to the core network, such as the use of a more flexible, cloud-native architecture that allows for better scalability and faster deployment of new services. Additionally, 5G core networks employ technologies like network slicing to create virtual networks tailored to specific use cases, ensuring that each application receives the necessary resources and performance.
Radio access network: The radio access network (RAN) in 5G is designed to support a wide range of frequency bands, from low-band spectrum for broad coverage to high-band millimeter wave spectrum for ultra-fast speeds and low latency. The 5G RAN utilizes advanced technologies such as massive Multiple Input Multiple Output (MIMO) antennas, which increase capacity and coverage, as well as beamforming to focus wireless signals more efficiently. This results in improved network performance, even in dense urban areas or challenging environments.

Furthermore, 5G RANs employ small cells, which are compact, low-power base stations that help provide increased capacity and coverage. These small cells can be easily deployed on streetlights, buildings, and other urban infrastructure, enabling network operators to expand 5G coverage in a cost-effective manner. The combination of these advanced technologies in the 5G network architecture enables it to deliver unprecedented levels of performance and support a wide array of applications and use cases, paving the way for the next generation of mobile communication.

5G technology represents a fundamental shift in the way mobile networks are designed, offering significant improvements in speed, latency, bandwidth, and network efficiency compared to 4G. Its innovative network architecture, which includes enhanced core networks and advanced radio access technologies, enables it to support a vast range of applications and use cases, from consumer services like streaming and gaming to mission-critical industrial applications like remote surgery and smart grid management.
