China and the United States are significantly ahead of other nations in their 5G rollout, with a combined 652 cities in which 5G is available. The Philippines is the country that is the closest in terms of 5G rollout, with active connections in 98 cities.

How 5G works:

5G is the fifth generation of wireless mobile networks, which uses advanced technologies to provide faster speeds, lower latency, and improved capacity compared to previous generations of mobile networks. Here is an overview of how 5G works:

1. Frequency Bands: 5G networks operate at higher frequencies than previous generations of mobile networks, including both low-band (sub-6GHz) and high-band (mmWave) frequencies. The use of higher frequencies allows for faster speeds and more data to be transmitted, but it also introduces challenges such as increased interference from physical obstacles and limited range.
2. Network Architecture: 5G networks are designed to be more flexible and scalable than previous generations of mobile networks, with a focus on network slicing and software-defined networking (SDN) technologies. This allows network operators to dynamically allocate network resources to meet changing demands and provide customized experiences for different types of users and applications.
3. Radio Access Technologies: 5G networks use a range of advanced radio access technologies, including massive MIMO (multiple-input, multiple-output), beamforming, and carrier aggregation, to provide increased speeds, lower latency, and improved reliability compared to previous generations of mobile networks.
4. Network Virtualization: 5G networks use network virtualization technologies like network function virtualization (NFV) and software-defined networking (SDN) to make the network more flexible and scalable, allowing network operators to quickly and easily deploy new services and applications.
5. Edge Computing: 5G networks introduce the concept of edge computing, where processing and storage capabilities are brought closer to the user, reducing the need to send data back and forth to a centralized data center. This can reduce latency and improve the overall performance of applications and services.

Overall, 5G networks use a combination of advanced technologies and flexible, scalable network architecture to provide a more advanced and capable mobile network experience compared to previous generations.

Features:

The features of 5G networks include:

1. Increased Speed: 5G networks are designed to provide significantly higher speeds than previous generations of mobile networks, with peak speeds of up to 20 Gbps possible in some cases. This allows for faster download and upload speeds for users and enables new applications and services that require high bandwidth.
2. Lower Latency: 5G networks are designed to have much lower latency than previous generations of mobile networks, with round-trip latency times of less than 1 millisecond in some cases. This enables real-time, interactive applications and services, such as augmented and virtual reality and autonomous vehicles.
3. Improved Capacity: 5G networks are designed to provide much greater capacity than previous generations of mobile networks, allowing for more devices to be connected to the network at the same time and reducing network congestion.
4. Network Slicing: 5G networks use network slicing technologies to dynamically allocate network resources to different users and applications, providing a customized experience for each user and application.
5. Edge Computing: 5G networks introduce the concept of edge computing, where processing and storage capabilities are brought closer to the user, reducing the need to send data back and forth to a centralized data center. This can reduce latency and improve the overall performance of applications and services.
6. Improved Security: 5G networks incorporate advanced security features, such as secure boot and secure element capabilities, to protect against hacking and other security threats.
7. Interoperability: 5G networks are designed to be interoperable with previous generations of mobile networks, allowing for a smooth transition to the new technology and avoiding disruption for users.

Overall, 5G networks are designed to provide a more advanced, capable, and secure mobile network experience compared to previous generations of mobile networks, with a focus on enabling new applications and services that require high speed, low latency, and improved capacity.
