Case Study: Motsipe Mining Corporation

Motsipe Mining Corporation $($MMC$)$ operates several mines across remote regions in South Africa. These mines are situated in challenging environments with limited access to communication infrastructure. To improve operational efficiency and safety MMC is exploring the implementation of a robust network infrastructure that can support real$-$time monitoring, data transmission, and communication between mining sites and headquarters.

MMC relies on effective communication and data transmission to ensure the safety of its workers and optimise mining operations. However, the remote locations of its mines present unique challenges, including limited connectivity, harsh environmental conditions, and the need for ruggedised equipment. Currently, MMC is facing a few issues. They have challenges with connectivity in remote locations. Establishing reliable connectivity between remote mining sites and headquarters is critical for transmitting real$-$time data and facilitating communication between field personnel and management.

The harsh environmental conditions in mining sites, such as extreme temperatures, dust, and vibrations, pose challenges for maintaining the integrity and performance of network infrastructure and equipment. MMC also requires sufficient bandwidth to support dataintensive applications such as real$-$time monitoring of equipment, video surveillance, and communication systems. Another issue raised is security concerns. Ensuring the security of data transmitted over the network is essential to protect sensitive information and prevent unauthorised access to critical systems and infrastructure.

Required:

Conduct a cost$-$benefit analysis of implementing satellite connectivity versus terrestrial$-$based solutions for MMC$\text{'}$s remote sites. Consider factors such as initial investment, ongoing operational costs, reliability, and scalability.

$(8$ Marks$)$

Evaluate the suitability of existing network equipment for operation in harsh environmental conditions prevalent in mining sites. Propose design modifications or alternative solutions to enhance environmental adaptability and durability. $(8$ Marks$)$

Evaluate the suitability of different network topologies for MMC$\text{'}$s remote mining sites. Consider factors such as reliability, scalability, and ease of maintenance. $(6$ Marks$)$

Propose a network topology design that maximises reliability and resilience for MMC$\text{'}$s remote mining sites. Consider redundancy options and fault tolerance mechanisms.

$(4$ Marks$)$

Assess the feasibility of integrating multiple network topologies, such as bus, star and ring, to meet the diverse communication needs of MMC$\text{'}$s remote mining sites.
