5G vs. 4G Cellular Technology: What Businesses Need to Know

5G networks are rolling out worldwide. Verizon, AT&T, Comcast, T-Mobile, and Sprint are among the leading 5G internet service providers.

Mobile and fixed 5G services are still limited in geographic reach, but ISPs are swiftly moving forward with expansion plans. In 2020, worldwide 5G wireless network infrastructure revenue will reach $4.2 billion, an 89 percent increase from 2019 revenue of $2.2 billion, according to Gartner.

“In the long term, 5G will impact all businesses, and it’s important to be at the forefront of using 5G,” says Emanuel Kolte, senior analyst at ABI Research. “Companies that gain experience with 5G before their competitors do will have a huge advantage.”

What Is a 5G Network? Introducing New Radio

5G is the fifth-generation mobile technology. The 5G NR — New Radio — is the new global standard adopted by the Third Generation Partnership Project, better known as 3GPP, the standards organization for a unified and more capable 5G wireless air interface. 5G supports diverse radio frequency spectrum bands with very high available bandwidth. The 5G Core is the center of the network and the anchor point for multi-access technologies.

5G vs. 4G: What’s the Speed Difference?

“5G is a transformational change from 4G,” says Heidi Hemmer, vice president of technology for Verizon. “5G will provide faster data speeds and carry a massive amount of data for a large number of simultaneous users.”

5G is reaching peak speeds of 1 gigabit per second to 10 Gbps, compared with 4G LTE’s peak of 300 megabits per second to 1Gbps. Average speeds for 5G are 50 Mbps and up versus 15 Mbps and up for 4G LTE, depending on device, location and motion status. 4G can support about 4,000 devices per square foot, whereas 5G will support around 1 million.

That speed and capacity are particularly important for IoT, says Kolta, where massive amounts of data from a dizzying number of devices and sensors must be collected, processed, transmitted and analyzed in real-time.

5G vs. 4G: How Does Latency Differ?

5G is estimated to be 60 to 120 times faster than average 4G latencies. With 5G, latencies — the time it takes for data from a device to be uploaded and reach its target — could eventually be under 10 milliseconds. That’s many times faster than the blink of an eye, says Hemmer.

“Latency does not depend on the radio interface only; it also depends where in the 5G Core network the traffic must complete a roundtrip,” Fellah notes.

Low latency is critical for applications that require rapid responsiveness, such as remote vehicle control.

5G vs. 4G: Does 5G Improve Security?

There’s no such thing as total network security. 4G addressed legacy networks security problems, such as crypto and side-channel attacks, and service providers built additional security features upon that foundation. Still, security holes exist. Researchers from the University of Iowa recently discovered security holes in 4G, including one that could lead to an authentication and synchronization failure attack.

Top security issues for 5G, as identified by RCR Wireless News, include the fact that as more network slices are created to support a variety of user equipment and requirements, the potential number of attack vectors will increase accordingly. And the sheer number of IoT sensors and other endpoints that 5G can accommodate provides a nearly limitless number of points through which a security attack can originate.

But Danny Tseng, a 5G/LTE technical marketing professional for Qualcomm, points out that a natural quarantine exists when a core network is sliced into different entities for different use cases. “So, in a way that’s more secure,” he says.

The 5G part of security is rock solid if one thinks of network security holistically, Tseng says. Many attacks can occur outside the connectivity level, such as on the applications side. “In the case of the enterprise looking into introducing new 5G services, they need to think about security as a whole,” he says. “It’s a system approach, not just the 5G part of it.”

Summary:

Why I selected this article:

5G is going to be the next big revolution happening in the network infrastructure. With it's features, the IoT sector, which needs a lot of devices and sensors to be connected to the internet continuously will also see a substantial growth. 5G will also help for the growth of a lot of technology fields for whom the slow 4G network speeds have been an obstruction. Autonomous cars which are facing problems due to slow 4G network speeds, 5G is going to be a big relief for them. Gaining experience with 5G is very important for the network companies to stay in the race.

Things I learnt:

5G is rolling out world wide. Though 5G is out of reach in many geographical regions, the ISPs are expanding swiftly. 5G is the new global standard for wireless communication. It is the fifth generation mobile technology. 5G supports a wide range of radio frequency bands. According to Gartner, there is going to be an 89% increase in the 5G infrastructure revenue in 2020 as compared to 2019.

5G supports very high available bandwidth and data speeds and can carry large amounts of data. The peak speeds range from 1Gbps to 10Gbps while 4G peak speeds range from 300Mbps to 1Gbps.5G can support one million devices per square foot. This will be very helpful for IoT because, there are going to be a lot of devices and sesors sending and receving data.The latency of the 5G netowork is 60 to 120 times faster than that of 4G.In 5G network slices are created to support a variety of devices. Due to this and the large number of IoT devices connected may increase the threats but these are controlled by having a quarantine around the whole network, this kind of makes 5G more secure than 4G. The security must be considered for the system as a whole. Even 4G has a lot of security holes now.

5G is going to influence speed and throughput. Mobiliy, connectivity and IoT are going to be benifited by 5G
