The document discusses spectrum fee approaches in Indonesia. Currently, Indonesia uses an apparatus-license-based fee structure where operators pay per transmission device. However, this may discourage network expansion. The proposed bandwidth-license-based approach charges operators based on the amount of spectrum bandwidth they license. This benefits operators expanding coverage aggressively. The document also outlines the various spectrum allocations and operators in Indonesia across various frequency bands such as 450MHz, 800MHz, 900MHz, 1800MHz, 2100MHz, 2300MHz and discusses factors influencing network capacity like bandwidth, signal-to-noise ratio and cell density.
