What is a 5G network?
A 5G network is an advanced cellular system based on the 3GPP standard and represents the next evolution from 4G technology. One of the significant advantages of 5G is its ability to operate across low, mid, and high-band spectrums, which was not possible with earlier generations that only utilized low-band spectrum.
Leading carriers like Verizon, Vodafone, and KDDI are currently in the process of building their 5G networks. To ensure improved coverage and high-speed capabilities, many carriers have acquired multiple bands of spectrum, including both low-band and high-band frequencies.
How much faster is 5G compared to 4G?
In theory, 5G promises an average speed of 10 Gbps, which is more than 100 times faster than the existing 4G technology. In real-world scenarios, the average 5G download speeds currently measure between 1.4 and 14 times faster than 4G.
As carriers continue to develop and expand their 5G networks, we can expect even faster speeds. Initially, 5G service operates on a non-standalone (NSA) mode, which rides on the existing 4G network, limiting the achievable speeds. However, with the completion of the rest of the network build (such as transport and core infrastructure), 5G standalone (SA) is expected to reach its targeted speeds. The speed experienced by users will also depend on the specific frequency band used for connectivity.
High-band spectrum offers the fastest speeds but faces challenges related to distance and building penetration. On the other hand, low-band spectrum provides slower speeds but excels in terms of wider coverage and better penetration capabilities. Mid-band spectrum strikes a balance between speed and coverage distance.
Where is 5G currently available?
As of now, commercial 5G networks have been deployed in 61 countries worldwide, indicating an impressive 80 percent increase since January 2020. Several countries, including Saudi Arabia, South Korea, Australia, Taiwan, Canada, Kuwait, Switzerland, Hong Kong, Germany, the Netherlands, and the United Kingdom, have achieved faster 5G download speeds compared to the United States. The reason for these higher speeds in countries like Saudi Arabia and South Korea lies in their wider utilization of midband spectrum by their respective 5G carriers.
What are the download and upload speeds of 5G?
5G download speed refers to the rate at which data is transmitted from the network to a device, encompassing files such as music, videos, and email. 5G has the potential to offer impressive download speeds ranging between 10 and 20 Gbps, making it approximately 100 times faster than the previous 4G technology.
On the other hand, 5G upload speed denotes the rate at which data is sent from a device to the network or the targeted endpoint, such as cloud storage or another device. Although upload speeds are generally slower than download speeds, 5G manages to improve this aspect as well, achieving upload speeds up to 30 percent faster than 4G.
What is mmWave?
mmWave, also known as millimeter wave or millimeter band, refers to high-band spectrum within the radio frequency spectrum. It exists in the wavelength range of 24 GHz to 100 GHz and remains relatively underutilized. Millimeter wave bands offer exceptionally high data rates, but their coverage distance is limited. Moreover, obstacles such as buildings and trees can hinder their propagation.
To address these limitations, mmWave technology can be deployed in conjunction with lower-band radio frequencies to provide a balanced service that ensures both high-speed capabilities and broader coverage. In the future, mmWave is expected to play a crucial role in supporting massive Internet of Things (IoT) applications.
Exploring the Potential Advantages of 5G

How might 5G revolutionize the IoT?
Expanded Capabilities of 5G Networks
5G brings a range of advantages such as increased bandwidth, low latency, and improved power management that significantly enhance the performance and longevity of IoT devices. Moreover, carriers can offer private networks and network slicing, enabling businesses to receive tailored connectivity for various IoT use cases.
Use Cases Enabled by Network Slicing
- Enhanced Mobile Broadband (eMBB): Providing higher bandwidth for applications like smart cities, infotainment in vehicles, and cloud services.
- Ultra-Reliable Low-Latency Communication (URLLC): Supporting real-time critical applications like autonomous driving and industrial robotics.
- Massive Internet of Things (mIoT): Serving billions of low-cost, long-range, and energy-efficient connected devices across remote locations and cloud applications.
Optimized IoT Edge Networks
To fully leverage 5G speeds and benefits, companies will need industrial IoT networking devices capable of evolving to 5G connectivity spectrum for diverse use cases. Modular, industrial routers can support both cellular and low-power connectivity, extending secure and reliable enterprise networking from the factory floor to remote outdoor sites. Automation tools for zero-touch deployment and centralized control will be essential for managing large-scale IoT deployments.
Examples of 5G IoT Use Cases
The combination of 5G speeds and low latency offers potential benefits for IoT applications in various sectors. Two prominent examples are:
- Healthcare: 5G can optimize wearable devices and other technology tools used in medical care, enhancing efficiency and information sharing among healthcare teams.
- Smart Cities: 5G’s low latency is beneficial for video-as-a-sensor technology, enabling applications like crowd monitoring, traffic analysis, and pedestrian safety. First responders can use real-time tactical feeds to improve situational awareness, and drones can share critical information.
Service-Centric Networks for IoT Support
To fully capitalize on 5G’s potential for delivering new services and supporting IoT use cases, a service-centric network is essential. This network type provides flexibility, control, and end-to-end management for differentiated services across wireless and wireline domains. It involves steps like implementing next-gen IP-based traffic handling, extending IP to endpoints, and laying the groundwork for end-to-end automation.
Next-generation services will leverage 5G’s improved bandwidth and density to create custom virtual networks tailored to specific service needs. A service-centric network enables efficient traffic handling on a per-flow basis and facilitates the delivery of various differentiated services over the same infrastructure through end-to-end automation.
