​​The Challenges of Wireline Network Engineering in Telecommunication Networks

1. Network Planning and Engineering :

The network planning and engineering process in a wireline network is intricate and demanding. It necessitates selecting optimal technology and carefully considering its potential effects on performance, reliability, and scalability

Failure to adequately assess or properly study the following factors before deployment could lead to the next:

● Geographical Area of Service: Misjudgments in the physical location and size of the area where the network services will be provided can lead to inadequate coverage or overinvestment.

● Anticipated User Demand: Underestimations or overestimations of the expected number of users and the volume of data traffic they will generate can result in network congestion or underutilized resources.

● Nature of Services to be Offered: Misalignment between the type of services provided over the network, such as voice, data, video, etc., and the chosen technology can lead to poor service quality or user dissatisfaction.

● Future Expansion Plan: Lack of foresight in the network’s projected growth and expansion plans, including potential increases in user demand and geographical coverage, can lead to scalability issues and possible costly network upgrades. For instance, in urban areas, FTTH or FTTB may be ideal for high-speed connectivity, while in rural areas, cost-effective solutions like FTTN or FTTC may be more suitable.

2. ​FTTx Rollout Strategy :

The successful deployment of FTTx networks requires meticulous planning and execution, as various challenges arise throughout the process.

● Design Phase – Delivering Optimal Service: Creating an FTTx network that optimally serves end-users during the design phase is crucial. Several factors must be considered, such as distance from the central office to customer premises, customer density, and service types.
For example, densely populated areas can require intricate network designs to handle the high demand for bandwidth, leading to increased deployment costs and technical intricacies.
The research, performed by RVA LLC Market Research & Consulting (RVA), shows that fiber providers passed 7.9 million additional homes in the U.S. in 2022, representing the highest annual fiber broadband technology deployment ever, even with challenges in materials supply chain and labor availability.

● Build Phase – Addressing Practical Obstacles: The build phase encompasses the practical aspects of network construction, considering existing infrastructure, geographical conditions, environmental considerations, and regulatory requirements.
Alternative deployment methods like aerial fiber may be considered in rural areas with challenging terrain. However, this introduces challenges regarding infrastructure availability and regulatory compliance. For instance, gaining the necessary permissions for installing aerial fiber and ensuring structural integrity can be time-consuming and pose logistical difficulties.

● Operation and Maintenance Phase: Sustaining Network Performance: The operation and maintenance phase involves monitoring network performance, troubleshooting issues, and conducting regular maintenance activities. However, this can be resource-intensive for network operators. It requires skilled personnel, robust infrastructure, and proactive measures to maintain optimal network performance.

​3. Operational Support and Preparations :

Moving from old network systems to FTTx is a massive undertaking in itself. One of the biggest challenges is managing outdated and inefficient legacy systems while preparing to transition to FTTx. Compatibility issues often arise due to differences in technology, hardware, or software during this migration. The industry must ensure minimal disruption to existing services during this transition to avoid customer dissatisfaction and potential loss of business.

​​

​4. CAPEX and OPEX Regulations :

Procuring equipment and establishing the network infrastructure constitute the initial expenses encompassed by CAPEX. In contrast, OPEX comprises ongoing maintenance, upgrades, and staff salaries. Underestimating these expenses can hamper overall progress, leading to budget overruns and project delays.

Furthermore, CAPEX and OPEX regulations complicate matters. When a telecommunication network company aims to expand its fiber network into rural areas, it must allocate funds for substantial CAPEX requirements, including laying new fiber lines. Simultaneously, the company must effectively manage OPEX, encompassing maintenance tasks for the fiber network and providing adequate customer support. Adhering to financial regulations, including accounting standards and tax laws, is necessary to ensure profitability while meeting regulatory obligations, which is usually a big struggle.

​​

​5. Skills and Capabilities :

Wireline Engineering is wrestling with a substantial skills gap that the ongoing Great Resignation has exacerbated. Amidst this mass exodus of talent, there’s a notable shortage in the skill sets required for top network engineering and operations roles. According to a recent report by Eightfold AI, a staggering 33% of these roles lack the necessary skills to address emerging trends in telecommunications, particularly in areas such as 5G and FTTx.

Further complicating this issue is the lack of adequate training opportunities for professionals in the field. This could be due to budget constraints, time limitations, or a simple unawareness of the importance of continuous learning in this fast-paced industry. This skills gap underscores the urgent need for strategic talent management and investment in continuous learning and development.
