英文摘要 | The economics for the next generation wireless multimedia services in the IMT-2000 network are analysed. To estimate the investment cost, the IMT-2000 network are classified into radio access network (RAN) and core network (CN), and the number of network equipments required to provide services are calculated. Based on the reference traffic in ITU, the number of equipments in the RAN is evaluated, and the number of CN equipments is computed by using the terminating capacity of the 2nd generation personal communication systems (2G PCS). Using the user's demand and the operating cost reflected in the 2G PCS, the net income is then estimated. The break-even point, net present value and rate of return are compared under various system parameters such as the reference traffic, service type and market share. The results indicate that the investment cost can be recovered after the 5th business year when the market share is the same for three network operators. Results for several types of service ratio show that the cumulative net income increases as the ratio of circuit service increases until it reaches a certain level (30%). |
