This letter examines a monopoly pricing scheme for small cells randomly deployed, by proposing their profit model, which takes into account the average data rate and user blocking probability. We further consider a dynamic traffic load on small cells such that operational expenditure for downlink transmission power cost and maintenance cost can be included in the profit model. Together with user surplus, we examine dowlink transmission power of maximizing profit, feasible price ranges, and monopoly price based on some system parameters, e.g., pathloss.
