四、资金开支(CAPEX)项目 1．基站、边缘和核心网络本商业案例假定的是一种“零起点”式部署,因此除了要有专门的WiMAX设备外,还必须为核心和边缘网络设备留出一定的空间(参见图3)。在开始提供服务之前,大多数设备都应已安装到位。在开始的时候,不必要求所有的基站和基站设备都安装起来,一些基站可以过一段时间后针对具体的市场分区或根据经营商感兴趣的地理区域情况来安装。然而在大都市地区,最好安装足够多的基站,以满足一个大市场的需求,以便尽快收回固定基础设施成本。对于含有经营商安装的、带有定向天线的室外用户设备(CPE)的固定业务来说,也应该安装足够多的基站,并精心设置基站的地
Fourth, capital expenditure (CAPEX) project 1. Base Station, Edge, and Core Network The business case assumes a “zero-start” deployment, so aside from having a dedicated WiMAX device, you must leave room for core and edge network devices (see Figure 3). Most devices should be in place before you start providing services. In the beginning, it is not necessary to require that all base stations and base station equipment be installed. Some base stations may be installed after a period of time for a specific market segment or according to the geographic region in which the operator is interested. However, in metropolitan areas, it is best to install enough base stations to meet the needs of a large market in order to recover the fixed infrastructure costs as quickly as possible. For fixed services with operator-installed outdoor user equipment (CPE) with directional antennas, there should also be enough base stations installed and the base stations carefully set up
