Infrastructure sharing is a practical resource utilization strategy among mobile network operators
(MNOs). The rapid growth of data flow and technology migration has increased the costs for both
infrastructure deployment and management. Hence, to ensure effective resource utilization, researchers
propose a joint venture towers construction for the mobile network in Tanzania. Cost reduction
analysis for tower construction has been done through game theory. It has been observed that there
is significant cost saving by the MNOs sharing the infrastructure. Based on game theory, it was
found that 50% of the cost can be saved when the MNOs cooperate in tower construction, which in
turn improves services to the users and increase the network rollout to the remote area. In general,
network infrastructure sharing (NIS) benefits both operators and the public at large. The MNOs can
have a significant financial saving by avoiding the costs of construction or upgrading the overlapping
sites, consolidating the existing sites, and by reducing expenses related to rents, maintenance, and
transmission. |
