In recent years, 5G adoption has been viewed as a race, with the earliest adopters seen as the "winners" — of the biggest business opportunities and the first chances to sell the new technology to customers. But an array of 5G issues and challenges have caused deployment to play out a bit differently than anticipated. [1]

Figure 1. Challenges Faced by 5G

Figure 1 shows evolution of wireless networking technologies like 5G in this regard is paving the way for successes for every other industry in the business world today. 5G technology is the enhanced version of its predecessor technology 4G LTE. Promised to deliver high speed, bandwidth with low latency, 5G has more to offer that could bring revolutionary changes and every sector is eager to implement this unparalleled technology to reap significant benefits with a competitive advantage. Mobile operators are taking initiatives to rollout 5G faster and make it live to more and more users. [2]

The Technological Challenges

Interference between Inter cells The differentiation in the size of traditional macro cells and concurrent small cells leads to interference.

Efficient Medium Access Control: In a scenario where the dense deployment of access points and user terminals is required, the latency will be high, and the user throughput will be low. Additionally, hotspots will not be competent with cellular technology to provide high throughput. Therefore, in-depth and adequate research to optimize the technology is required to smooth out the issues. [3]

Building complex and dense networks: 5G networks will be significantly more complex than current networks. One component of this increasing complexity is the need for denser networks. New 5G antennas and RAN hardware, although powerful, cover significantly less space compared with existing 4G macrocells. This means similar coverage requires more 5G hardware and supporting software - a number that multiplies further as traffic moves indoors.

Keeping operating and maintenance costs low: Adding the necessary hardware required for 5G networks can significantly increase operating expenses (OpEx). Of course, these costs go beyond the hardware itself. Networks must be configured, tested, managed, and regularly updated - all things that exponentially increase OpEx. [4]
