Fifth Generation Technology: What is 5G? What is 5G

The fifth-generation network is the most advanced type of communication network. As you know, there are many networks. Today we will explain in detail what this network means.

What does the 5G network mean?

Fifth generation technology, known as 5G for short, is the fifth generation of wireless cellular networks. The first four generations brought a new level of connectivity, with 3G and 4G focusing on improving mobile data; 5G technology seeks to continue this trend and expand use of mobile broadband access. The fifth-generation technology, alongside the fourth-generation technology, will completely replace it after a while. This network is considered a good development in the world of information technology.

The fifth generation of cellular communications networks, also known as 5G, is a new development in cellular communications networks and is considered the successor generation to previous generations such as 3G, 2G, and 4G. 5G networks are designed to provide noticeable improvements in performance and capabilities at various levels.

Types of fifth-generation networks

There are two types of fifth-generation networks: (independent networks) and (non-independent networks). We will explain and explain both types in this part of the article.

Standalone (SA).
Independent networks rely on 5G technology, as they use frequency bands and infrastructure dedicated to the 5G network. SA networks offer the best performance and capabilities of 5G technology, such as enhanced mobile broadband (eMBB), ultra-reliable low-latency communications (URLLC), and massive machine-type communications (mMTC) scenarios. SA networks include a comprehensive implementation of the Secure Network Backbone (SBA) concept. Everything Network (EN-DC), allowing full use of the capabilities of 5G technology.


Non-Stand Alone (NSA).
Non-stand-alone (NSA) networks use a combination of 4G and 5G technology. These networks use 4G bandwidth and infrastructure for some services such as Initial Access and Traffic Management. NSA is a transitional technology that allows network operators to deploy 5G services while building dedicated 5G infrastructure. These networks provide a smooth transition for users from the fourth generation (4G) network to the 5G network using Dual Connectivity technology.

What are the options for the fifth generation (5G) network?

In addition to the types of networks in the fifth generation (5G), there are also what are known as “options” associated with 5G networks, which express multiple paths for transmission and implementation across the network in this advanced technology. 

Options classify a different group of Base station BS (gNBs, eNBs) and Core networks (Evolved Packet Core, EPC, or 5GC). Naturally, the operator will not suddenly replace the fourth generation network (4g (eNBs+EPC)) with the fifth generation network 5G (gNBs+5GC)!

There will be different transmission and tracking paths. Options vary depending on their use, the extent of their coverage, and the data speeds they can support. Now here are these options.

  1. Option 1: Oddly enough, it's not for 5G at all. Actually, it is for a good old 4G network with eNBs connected to EPC and is there as a reference or starting point.
  2. Option 2: It refers to gNBs connected to 5GC. With support for all features of 5G technology
  3. Option 3: It is the first step for 5G technology, allowing operators to deploy 5G services without having to replace the 4G network infrastructure. This means keeping the legacy EPC and eNBs while adding gNBs in the radio network. These gNBs add more New Radio (NR) capacity, but they cannot operate alone. Reliance depends on the presence of an eNB as a companion and on the presence of a control panel connection to the core network, and it is classified as a non-standalone (NSA) network.
  4. Option 4: Option 4 is the opposite of option 3. The 5GC is used as the core network in the radio network, with gNBs but also eNBs in non-stand-alone NSA mode which means they do not operate on their own. They need to get a gNB as a compensation. It is classified as a stand-alone network.
  5. Option 5: Option 5 uses the 5G Core Network (5GC) with 4G eNBs in the 5GC radio network. It may be suitable for an operator who does not need additional radio capacity but wants to take advantage of One of the new 5GC functions.
  6. Option 6: It is a core 5g network (5GC) with eNBs plus additional gNBs in NSA mode. In option 5 the operator may realize that more radio capacity is actually needed and therefore add gNBs in strategic places in the network. It is also classified as an independent network StandAlone SA.

How does 5G technology work?

5G technology transmits huge amounts of data and information over shorter distances than 4G networks. This helps in the speed and consistency of communication signals. Even while moving. This network also uses less energy.

What is the difference between 4G technology and 5G technology?

Some notable differences allow 5G to do things that 4G cannot. The results of this comparison are as follows.

Fifth-generation technology is faster than fourth-generation technology, with the ability to transfer a greater number of bits per second over the network. And with new upload and download speeds, you can download movies and large files in seconds, not minutes.

5G is more responsive than 4G and has lower latency, meaning the time it takes to communicate from one device to a network. Since devices can "talk" to the network faster, they will get data faster.

5G technology consumes less power than 4G technology as it can quickly switch to low power use when cellular radios are not in use. This helps extend the device's battery life to allow devices to maintain their charge for longer.

5G provides strong, fast service more reliably than 4G due to better bandwidth usage and more connection points. With less strain on the network, 4G data costs could be lower.

5G can carry more devices than 4G because it expands the available radio waves. This, in turn, will reduce overload issues that lead to slow service once 5G is operational.

Overall, 5G technology is a huge leap forward for cellular networks. Similar to the mythical shift from wired dial-up to high-speed broadband, we will begin to rethink what mobile data can do.

There are three frequency bands at the heart of 5G networks.

    1. High-band 5G (mmWave) provides the highest 5G frequencies ranging from 24 GHz to 100. Because high frequencies cannot easily move through obstacles, high-band 5G is inherently short-range. Furthermore, mmWave coverage is limited and requires more cellular infrastructure.
    2. Mid-band 5G operates in the 2-6 GHz band and provides a capacity layer for urban and suburban areas. Rates in this range reach 100 megabits per second.
    3. Low-band 5G operates under 2 GHz and provides wide coverage. This band uses the available spectrum currently in use for 4G LTE, essentially providing the 5g LTE architecture for 5G-ready devices now. So 5G low-band performance is similar to 4G LTE, and supports the use of 5G devices on the market today.

        The future of fifth generation technology and cybersecurity

        To avoid widespread vulnerabilities in local mobile networks, technology developers must be more concerned with 5G security.

        There is a need to establish the foundations of 5G security in networks first; Service providers will begin to focus on software protection to cover 5G-specific risks, and will need to collaborate with cybersecurity companies to develop solutions for encryption, network monitoring, and more.

        Manufacturers need an incentive to increase their security efforts. The security of 5G technology is only as strong as its weakest link, but the costs of developing and implementing secure technology do not motivate all manufacturers to focus on cybersecurity, and this is especially true for cheap products such as children's smartwatches and cheap children's smart monitors. If manufacturers receive benefits that compensate for their minimal losses, they may be more eager to strengthen consumer protection.

        It is essential to educate consumers about IoT security, and the wide variation in security quality indicates that product identification standards are needed. Since users have no way to easily know how secure IoT devices are, smart technology manufacturers may start to take accountability with the naming system. The FCC classifies other forms of wireless transmission, so the growing market for IoT devices may also be included. In addition, users need to know the importance of securing all Internet devices through software updates.

        Efforts to improve security are taking place alongside the initial rollout of 5G technology. But because we need real results to improve protection, the work will continue long after 5G is implemented.

        How to prepare to use 5G technology

        5G is a little different than you might think, but you should still be prepared. Although the implementation process will take a long time for the technology to become widespread and in use, some areas have seen upgrades begin to appear, so be sure to take security and privacy precautions as much as possible.

        Use a VPN to prevent strangers from accessing your data without your permission and from spying on your online activity.

        Always use a strong password. Always use passwords when available and make them very strong. Long strings of random and varied letters and symbols are some of the best possible passwords; Combine uppercase and lowercase letters, special symbols, and numbers.

        Update the default access passwords for all IoT devices you use. Follow your device's instructions for updating the default "admin/password" mode for your devices. To find this information, consult the manufacturer's technical manuals or contact the company directly.

        Cybersecurity concerns for 5G technology.

        When it comes to 5G and cybersecurity, here are some key concerns.

        Decentralized security: Pre-5G networks had fewer hardware traffic nodes, making it easier to perform security checks and maintenance, but dynamic software-based 5G systems have far more traffic routing points. To be completely safe, all of these things must be monitored. Since this can be difficult, any unsecured areas from other parts of the network may be damaged

        Many IoT devices are manufactured without any security measures. Not all manufacturers prioritize cybersecurity, as is the case with many low-end smart devices. 5G technology means greater utility and more potential for the Internet of Things; As more devices are encouraged to connect, billions of devices with varying security mean billions of potential compromise points! Smart devices such as televisions, door locks, refrigerators, speakers, and even small devices such as a fish tank thermometer can represent a vulnerability in the network. The lack of security standards for IoT devices means that network attacks and hacking can be rampant.

        Weak encryption early in the communication process exposes device information that can be used in targeted attacks on IoT devices. This information helps hackers know exactly which devices are connected to the network, and details such as operating system and device type (smartphone, car modem, etc.) can help hackers plan their attacks more precisely.
