Telecommunications operators need to solution to extend the lifecycle of Base Transceiver Station (BTS) to minimise their capital expenditure (Capex). Currently, there is a single tower for single operator, which means the business is not managed optimally. This study aims to optimise existing BTSs by maximising its capacity and its strategic location via Particle Swarm Optimisation (PSO). The PSO is aimed at reducing the number of towers and encourage sharing between operators. Based on PSO data by optimising existing BTS capacity and tower sharing, a 72% reduction in capex can be achieved. Therefore, infrastructure sharing is vital to reduce Capex problem faced by the operators. The study proposes open access among operators.
