Abstract
A current major challenge for telecommunications networks is power consumption across the network, representing a significant proportion of operational costs. This is exacerbated by the constant increase in demand for bandwidth, while also trying to achieve cost reductions and meet environmental goals. An ongoing approach to this is to move away from older less energy efficient networks, through long term programmes migrating consumers to new technologies and through depowering legacy platforms across sites. Optimising this approach needs to consider numerous background factors including field resource constraints, planning period duration, the power reduction obtained for a given time to depower different equipment types, and the number of site visits required. Given the population of devices available to depower within a planning period, a knapsack based approach can be employed to find the optimal selection. This can be implemented through considering individual devices or aggregating them by location. Each approach is seen to have distinct benefits: considering devices individually can give maximal power reductions, while considering the aggregates reduces number of visits on site required. Simulations suggest that a hybrid solution comparing both approaches within a planning period and selecting the best per planning period can deliver a better outcome than only adopting a single approach. We explore a heuristic for choosing the optimal strategy during planning.
