The goal of this paper is to estimate the capital investment in mobile telephony network's equipments, by using Cobb-Douglas model to forecast the number of subscribers for the next years in the country. Then by presenting a master plan for Base Station Subsystem (BSS) and Network Switching Subsystem (NSS) parts of the network, the required equipments and also the capital investment amounts are estimated. In the BSS plan, the number of Base Transceiver Stations (BTS) with various configurations and also Base Station Controllers (BSC) with different capacities and required accessories (such as tower, antenna, feeder, power supply and transmission equipments between BTSs and BSCs) are determined. In the NSS plan, an architecture is proposed for network's traffic (including signaling). The routing plan and required interfaces with Public Switched Telephone Network (PSTN) and Public Data Network (PDN) are also presented and the capacity of network's nodes and E1 links are determined. Based on the mentioned plan and also the typical cost of different equipments, offered by domestic and foreign vendors, the capital investment of 26.7 trillion Rials seems to be necessary to increase the penetration rate from 12.4% to 48.4% in mobile telephony network.
