1. Understanding 4G Technology
4G, the fourth generation of mobile networking, laid the groundwork for modern mobile connectivity. It represents a significant leap forward compared to its predecessors. Functioning through a radio system, 4G networks use base stations to transmit radio frequency signals between the network and devices. This evolution brought about faster speeds, better spectral efficiency, and higher network capacity.
Some key benefits of 4G include enhanced cell density, improved VoIP capabilities, and increased bandwidth. These features made 4G the dominant mobile technology of the 2010s, enabling innovations and paving the way for widespread adoption. The rise of 4G coincided with the development and implementation of the Long-Term Evolution (LTE) standard. LTE helped 4G achieve its promise of faster speeds and more reliable network performance. It bridges the gap between older 3G technology and true 4G capabilities.
Key capabilities of 4G LTE include:
- Support for diverse traffic types, including voice, video, and data.
- IP-based communication methods for all traffic types.
- Orthogonal frequency-division multiple access and carrier aggregation for efficient bandwidth sharing among devices.
The 4G era spurred the growth of various networking trends, like the rise of the Internet of Things (IoT), the proliferation of smartphones, and the expansion of remote and mobile workforces. These trends increased the demand for faster speeds and greater cell density.
While 5G is rapidly expanding, 4G remains widely used globally. A December 2024 report from 5G Americas and Informa TechTarget’s Omdia indicates that 5G is projected to surpass 4G connections in North America in 2025. However, 4G is expected to remain the dominant wireless connectivity option in other parts of the world.
Mobile network operators (MNOs) continue to maintain their 4G networks, ensuring interoperability and bridging the digital divide. This allows users on legacy network standards to stay connected while carriers deploy 5G infrastructure and customers transition to the new standard.

2. Exploring the Capabilities of 5G
5G represents the latest evolution in cellular network technology. Similar to 4G, 5G utilizes radio waves to connect devices to network infrastructure and facilitate data transmission. However, 5G distinguishes itself through its broader utilization of radio frequencies, enhanced speeds, network slicing capabilities, and other advanced features.
5G base stations employ advanced technologies such as network slicing, orthogonal frequency-division multiplexing (OFDM), and massive multiple input, multiple output (MIMO) to deliver faster connections and optimize network performance.
There are two primary types of 5G infrastructure:
- Standalone (SA) 5G: This encompasses a 5G radio access network, a 5G core, and 5G-compatible devices. SA 5G represents the full potential of the technology, enabling network slicing and ultra-low latency.
- Non-Standalone (NSA) 5G: This leverages existing 4G LTE infrastructure and a 4G core as carriers build out their SA 5G network infrastructure. This allows for a hybrid operational mode during the transition to full 5G deployment.
While NSA 5G relies on the LTE standard, it also introduces 5G New Radio (5G NR), which is intended to eventually replace LTE. 5G NR is the radio access technology standard that enhances 5G connectivity and enables it to offer faster speeds, lower latency, and greater capacity. It builds upon the strengths of LTE while introducing new benefits.
Key advantages of 5G include:
- Increased energy savings for connected devices.
- Enhanced connectivity.
- Faster network speeds.
- Real-time communication capabilities.
5G also has the capacity to operate on a new high-frequency spectrum known as millimeter wave (mmWave), which uses wavelengths between 30 GHz and 300 GHz, compared to 4G LTE’s wavelengths of under 6 GHz. Due to the characteristics of the mmWave spectrum, 5G requires new small-cell base stations for optimal performance.
5G’s enhanced capabilities enable operators to provide connectivity that supports next-generation wireless network infrastructures. Although many MNOs launched small, early 5G deployments in the late 2010s, they are still in the process of fully developing their 5G infrastructure.
3. Latency: A Critical Comparison
Latency, the delay in data transmission, is a crucial performance metric for any network. 5G offers significantly lower latency compared to 4G. SA 5G can achieve latency under 5 milliseconds, while 4G latency typically ranges from 20 ms to 40 ms. This reduced latency leads to improvements in responsiveness and overall network efficiency.
| Feature | 4G | 5G (SA) |
|---|---|---|
| Latency | 20-40 milliseconds | Under 5 milliseconds |
| Responsiveness | Moderate | High |
| Network Effciency | Moderate | High |
4. Download Speeds: The Need for Speed
One of the most anticipated improvements with 5G is the potential for significantly faster download speeds. 4G typically provides download speeds of up to 20 Mbps to 100 Mbps. In ideal conditions, using mmWave technology, 5G maximum download speeds can reach between 10 Gbps and 20 Gbps. However, typical speeds are closer to 1 Gbps to 3 Gbps.
| Feature | 4G | 5G (Typical) | 5G (Ideal) |
|---|---|---|---|
| Download Speeds | 20-100 Mbps | 1-3 Gbps | 10-20 Gbps |
| Technology | LTE | 5G NR | mmWave |
5. Base Stations: Infrastructure Differences
The type of base station used to transmit signals is another key difference between 4G and 5G. 4G transmits signals from traditional cell towers. 5G, on the other hand, utilizes small-cell technology due to its faster speeds and mmWave frequency bands. Carriers deploy high-band 5G in small cells, often about the size of pizza boxes, in multiple locations. While 5G also uses cell towers for its lower-frequency spectrums, the use of small cells is a defining characteristic.
6. OFDM Encoding: Signal Processing
OFDM encoding is a method of splitting a wireless signal into multiple, narrower frequency channels (subcarriers) within the same bandwidth to minimize interference. Each subcarrier carries its own portion of the total data, which increases data throughput and improves download speeds. 4G LTE typically uses 1.4 MHz to 20 MHz channels, while 5G uses 100 MHz to 800 MHz channels when utilizing mmWave.
| Feature | 4G LTE | 5G (mmWave) |
|---|---|---|
| Channel Width | 1.4 – 20 MHz | 100 – 800 MHz |
| Technology | OFDM | OFDM |
| Interference | Minimized | Minimized |
7. Cell Density: Supporting More Devices
Small-cell technology enables 5G to increase cell density and enhance network capacity. While 4G aimed to improve speeds and capacity, it didn’t fully meet the high-speed requirements. 5G addresses this limitation by increasing density to support more users and connected devices. This increased density translates to greater mobile device and connection capacity.
8. Transitioning from 4G to 5G
While 4G remains in use, technology experts recommend that enterprises transition to 5G whenever possible. Beyond the advantages of faster speeds and lower latency, 5G offers improved reliability and security compared to 4G. Its capabilities are well-suited for industries that require real-time communication, high density, and low latency. This includes sectors such as healthcare, manufacturing, autonomous vehicles, and fixed wireless access.
5G technology is still evolving, but businesses and consumers can adopt it now. However, availability depends on location. According to 5G Americas and Omdia, 5G reaches 70% of the population in North America.
Access to 5G also depends on carrier availability. Most major MNOs in North America have rolled out SA 5G deployments, while some MNOs still have NSA 5G deployments. While NSA 5G is an improvement over 4G LTE, offering reduced latency and faster speeds, it isn’t the complete 5G experience.
NSA 5G serves as a bridge from 4G LTE to 5G. This deployment method allows MNOs to implement 5G capabilities on their existing 4G infrastructure. Early 5G adopters utilized NSA 5G as they transitioned from legacy cellular technology. While many MNOs now offer SA 5G deployments, those that have yet to build a full-fledged 5G network can use NSA 5G as a starting point.
