The challenges that the 5G network put across are at a high scale. To download at a speed of 10-20Gbps, it requires an unwavering frequency of up to 300GHz. The powerful signal range necessitates such an incredible infrastructure to make the most out of 5G technology. Also, data-driven services need to be secure with multi-layer security practices. 

The tremendous expectations following the 5th generation mobile network are worth-while to take the whole economy off the ground with millions of jobs, trillions worth goods and services, and GDP growth, says Qualcomm. At the same time, it rollout countless challenges that need to be addressed at a fast pace to afford 5G technology into the daily lives of people.

Here let’s check the critical 5G technology challenges,

5G Big Data Management: 

With the advent of 5G network technology, the number of connected devices would breach the approximate estimate of 50 billion. Thereby, the surge of data volume would also multiply exponentially. The drastic movement of every industrial sector to 5G-based use cases contributes to the growth of huge data exchange. However, to reap the features at their fullest, many cloud-based data services need to be redesigned to align 5G network standards.

The growing popularity of IoT technologies makes data management more complex with the 5G network. Industries have to set up virtual as well as on-premise data infrastructures to maintain a reliable hybrid environment to gain an agile throughput. A unified data architecture that can incorporate speed, integration, and analysis of data is essential to make use of the distributed data.   

Also, to leverage the ever lowest data latency, i.e. 1 millisecond with a device capable of 1million per sq km, enterprises have to renovate their infrastructure to regulate such a velocity and volume of data. Further, to exchange, store and analyze the dense data exchange network without compromising its sophisticated features, numerous locally connected mini-servers and MIMO antennas are essential.  

5G Expanded Network Architecture:

5G network relies entirely on IP-based architecture to deliver reliable wireless data transfer in different environments. The key feature –low latency comes true only through strategic as well as interoperable working models of the network such as centralized RAN architecture. 

Any slightest form of distraction diminishes the actual efficiency of 5G network, so, 5G technology inescapably requires microcells for data exchange. It involves huge capital expense and implementation efficiency. 

Technologies such as MIMO and Beam Steering are quintessential to regulate the signals to target users. Also, the End to End (E2E) cloud-native architecture is imperative to cater to the diversified requirements of users along with greater control. To deliver a network design that is capable to deliver flexible, agile and scalable 5G service and align with multiple networking technologies the service providers should redesign the cloud architecture with SDN and NFV equipment. 

Besides, drastic renovations in RAN and Core networks are inevitable to yield the potential benefits of 5G. Moreover, integrating Software-defined Network (SDN) and Network Function Virtualization (NFV) as the promising support for the physical infrastructure for the effective network slicing and the allied operations is undeniable. To boost the enhanced mobile broadband service (eMBB) of 5G network across service-based geographies users need to procure NFC equipment to meet their specific service requirements.  

5G Edge Computing:

Edge computing enables fast data processing and enhances performance. It brings cloud-based services closer to users. With the growth of IoT devices and 5G implementation devices are d=getting ready to compute at eh closest distance via Edge computing technologies. However, it takes a lot of favorable conditions for this kind of computing into reality. 

Balancing the multiple bandwidths across the different networks is required to exchange the accumulated data to datacenters and end devices. Also, distributed computing in regard to the location and network capacity also take-part in the successful performance of edge computing. 

Though edge computing speeds up data processing with minimal latency, it is not a one-way process. Sharing data with the central data center and the edge computes points, data passes through the network across the gateways.

Data backup is another challenge posing by implementing edge computing. Hence, enterprises need to follow a stringent data backup and access strategy to comply with data management policies.

Security and Privacy:

The existing network-oriented security practices won’t work well with the gigantic 5G network cluster. The new network model with advanced architecture demands more sophisticated security measures. To protect loads of data exchanged in milliseconds across the IoT devices, End to End protective measures are more recommended. 

Since 5G technology expands the mobility of devices with IoT technologies, data security will become vulnerable than ever before. As the number of endpoints becomes higher the risk factor associated with it will also go high. Unique authentication methods and stringent access gateways are necessary to stitch across the network. Also, technology-appropriate security layers have to be deployed around SDN and NFV endpoints. 

To mitigate the evolving 5G security challenges system-level security measures are required to protect the integrity of networks. 


Unlike the preceded mobile network services, 5G technology has wider scopes to change the way our world works today. It has inherited greater potential which can enhance the technologies to higher levels. However, 5G from a commercial viewpoint raises a lot of concerns in regard to security and data management. The existing infrastructure and endpoint equipment need a quick make-over to accommodate 5G network features. Also, meticulous system-level security practices are imperative to yield the amazing amenities of 5G technology with integrity.
