To provide the opportunity to research and illustrate best practice recommendations for LAN design, specifically for a company scenario requiring wired or wireless LAN installation.

In a corporate environment such as Eureka, a telephone and Internet-based concierge service handling sensitive customer information and employing 60 staff members across three shifts, effective LAN design is crucial. The choice between a wired 100Base-T network and a Wi-Fi network should be made based on specific organizational needs, including speed, security, reliability, and scalability.

I recommend implementing a wired 100Base-T Ethernet network for Eureka. First, this choice is supported by the network's capability to support data transfer rates up to 100 Mbps (according to the book, Chapter 7, p.188), which is sufficient for the data exchange requirements of a busy call center and online research activities. Wired networks offer higher stability and lower latency, which are beneficial for concurrent, high-speed data transmission and VOIP telecommunication tools used in such environments (Kurose & Ross, 2017).

Furthermore, security considerations strongly favor a wired LAN. Wired networks significantly reduce the risk of unauthorized access compared to wireless networks, which are vulnerable to interception from nearby outsiders (Odom, 2018). Given the sensitive nature of Eureka’s stored customer data, security is paramount. Using physical cabling ensures direct access, making it easier to control and monitor network access, thereby reducing the risk of data breaches (Cisco, 2021).

While Wi-Fi offers the advantage of mobility and flexibility, the potential for network congestion and interference could impair productivity. Wireless signals can be affected by physical obstructions, electronic noise, and overlapping channels, which may compromise connection quality in a busy office (Sharma et al., 2020). Additionally, the security vulnerabilities inherent in Wi-Fi, despite encryption, pose concerns about data confidentiality, especially for a company handling personal and financial information (Wang & Wang, 2019).

Therefore, based on speed, security, and reliability, a wired 100Base-T network aligns well with Eureka’s operational needs. To enhance operational resilience, a hybrid approach could also be considered—using wired connections primarily, supplemented with secured Wi-Fi for mobile devices or visitors. This arrangement can balance security with flexibility, provided that strict access controls and encryption protocols are implemented.

In conclusion, the optimal LAN design for Eureka, given the scenario, is a wired, high-speed, secure 100Base-T Ethernet network, with considerations for strategic wireless access to support flexible device use where necessary.
