Frequently Asked 5G Telecom Interview Questions

Job interviews are essential to the hiring process, as they help employers identify the best candidate for the position. They allow employers to assess a candidate's skills, knowledge, attitude, and experience in person. 

5G technologies are revolutionizing the way communication networks are deployed and used. It brings the network a wide range of frequency bands, advanced technologies, and improved performance and efficiency. It is also creating new opportunities for career growth, with its deployment in various scenarios and its impact on multiple sectors. 

After conducting research and compiling information from prior interviews, we created a list of 5G engineer interview questions.

Interview Questions on 5G Technology

• What do you understand by 5G Network?

Answer: The fifth generation of wireless technology, or 5G network, offers 4G LTE networks a competitive speed advantage, lower latency, and increased capacity. It may greatly affect how we live, work, and have fun.

With 5G wireless technology, more users will have access to higher peak data speeds of several gigabits per second (Gbps), extremely low latency, improved reliability, huge network capacity, and a more consistent user experience.

Speed: Compared to the median speeds of 4G LTE, 5G can deliver high speeds up to 10 times quicker.

• What features does 5G have?

Answer: 

The features of 5G include: 

• Faster download speeds: 5G networks are expected to be 100 times faster than 4G networks.
• Lower latency: 5G networks will have a latency of just one millisecond, compared to 50 milliseconds on 4G networks.
• Higher capacity: 5G networks will be able to handle significantly more users and devices than 4G networks.
• Greater reliability: 5G networks will be more reliable than 4G networks, making them less prone to outages and disruptions.
• More efficient spectrum use: 5G networks will be able to use the radio spectrum more efficiently, allowing for more capacity and higher speeds.
• Lower power consumption: 5G networks will be able to use less power, allowing for smaller and more energy-efficient devices.
• Improved support for IoT: 5G networks will be better equipped to support the growing number of connected devices in the Internet of Things.

• How do businesses use 5G networks?

Answer: 5G's quick data rates and good network reliability will greatly impact business. With 5G, businesses can function more effectively, and people will have quicker access to more information.

• How is 5G superior to 4G?

Answer: 5G is the fifth generation of wireless communication technology, much faster than 4G. It has a higher bandwidth, allowing for a much faster data transfer. 

This can be used for faster downloads, better streaming services, and even more data-intensive applications like virtual and augmented reality. 5G also has lower latency, meaning that responses from the network are much quicker than on 4G. 

5G is also expected to be more reliable than 4G, as it can handle more connections simultaneously and is less prone to interference from other sources. 

5G is more energy efficient than 4G, which can help reduce the power consumption of devices and networks. All these benefits make 5G a great choice for anyone looking for a faster, more reliable, and more energy-efficient internet connection.

• What exactly does "network slicing" mean?

Answer: In 5G, network slicing is a radical concept. Network components make up network slicing. These NFs have a specific service in mind and are hence specialised. For example, we can have network slices for IoT, regular UEs, and V2X. Latency, mobility, and data rates may be distinct user needs.

• What does virtualisation mean?

Answer: The adoption of virtualisation is supported by the service-based architecture of the 5G core network. A completely distributed, fully redundant, fully stateless, and fully scalable network may be implemented in an SBA. Many Network Instances may exist inside the same network configuration. Service delivery is made possible from anywhere, thanks to virtualisation.

• What exactly is unified access control?

Answer: The 5G core Network can be modified depending on administrator settings, organisational dynamics and endorser profiles. When congestion occurs in the 5G System, many factors decide which user should be allowed or refrained.

• Can 5G take over from WiFi?

Answer: The two technologies will probably coexist as network rollouts develop. Currently, 5G can replace Wi-Fi depending on the environment and coverage.

• How do you troubleshoot 5G network problems?

Answer: When troubleshooting 5G network problems, I typically start by gathering as much information as possible about the issue and the environment in which it occurs. I then use that information to identify the root cause and develop a plan to resolve the issue. This usually involves troubleshooting the hardware, software, and network configuration of the 5G network. I also use various network monitoring and analysis tools to identify and debug network-related problems.

• What does 5G New Radio mean?

Answer: 5G NR (New Radio) is the new air interface developed by 3GPP for the 5G network. It uses a much wider spectrum than 4G, allowing higher throughput and more reliable connections. It also incorporates advanced technologies such as Massive MIMO, beamforming, and Full Duplex.
