Significant Challenges in the Deployment of 5G Technology

Enterprise Networking Mag | Tuesday, August 02, 2022

Testing with 5G technical KPIs is required to guarantee that networks provide the connectivity, high-data throughput, low latency, and other features of 5G.

FREMONT, CA: Faster connectivity, ultra-low latency, and increased bandwidth are expanding society, revolutionizing industries, and significantly improving day-to-day experiences. 5G technology, faster than 4G, is opening up unseen prospects for consumers and businesses. Services that were formerly thought to be futuristic, such as e-health, connected automobiles, traffic systems, and advanced mobile cloud gaming, have already become a reality. Using 5G technology helps build a better, safer, and more sustainable future.

Development of 5G network

Some of the infrastructure required for 5G exists, such as macrocells, which are those enormous towers and masts presently used as telecommunications equipment. However, for 5G to be truly 5G, implementing small-cell technology in heavily populated locations can increase network capacity. 5G network infrastructure requirements include mmWave frequencies, which have a limited range. As a result, it requires an ultra-dense grid. Small cells can be placed on lampposts and the sides of buildings; however, numerous antennas are needed to service a specific region due to range constraints.


Adding 5G network infrastructure components necessitates the purchase of additional hardware and associated software. The costs of purchasing spectrum, configuring, testing, and managing networks - and, of course, such networks must be regularly maintained and updated. Many components of 5G technology are based on 4G networks, allowing operators to view their infrastructure as an evolution rather than a revolution. It facilitates investment. For example, by network refarming their 3G spectrum, companies can more readily improve the capacity of their 4G network, advancing to LTE features.

Backhaul concerns with 5G

5G networks' extremely dense tiny cells must accommodate hundreds of gigabits of traffic from the core network via backhaul and existing cellular system technologies. The technology that assisted in meeting LTE backhaul issues is beginning to show its age. The point here is that more fiber is placed, which is where deployment becomes complicated, not to mention expensive. Aside from money, laying fiber can take months, and even then, deploying fiber isn't always practical due to the location of each small cell. Rain and other environmental factors can degrade the efficacy of wireless signal transmission technologies. Operators must devise a new solution or rely on wired and wireless backhaul systems.
