There are many sound reasons for infrastructure sharing or pooling when rolling out NGNs. High costs of infrastructure rollout have an impact on what is charged to the customer. An expensive service is already an impediment to gaining a secure foothold in an environment where average purchasing power is low. Inadequate infrastructure development can lead to adverse electromagnetic impacts, resource saturation, issues of right of way, and so on. The number of fixed and mobile operators, scarce radio resources, high investment costs for NGNs, and the need to optimize the use of infrastructure, are all arguments in favour of infrastructure sharing. The advantages are:
rapid and efficient network rollout;
lower investments costs for operators;
guaranteed universal access and services;
lower tariffs;
smooth network expansion at the national level.
