Based on the current state of the industry, the cost of a BS as described in this
scenario can be conservatively estimated to be about $30K. The cost of additional networking
equipment required at the site of the base station can be estimated to be
about $10K. Additional $10K (a very rough estimate) may be required for additional
installation expenses such as cabling and mounting. Therefore, based on this rough but
very conservative estimate, the cost of deploying a WiMAX base station is about $50K.
In addition to the base station, a CPE device (a WiMAX subscriber station) would be
required at each customer site; the cost of each is estimated to be about $1.5K.
The WiMAX network thus deployed can deliver a total of 225 Mbps of bandwidth
shared among the users of the network, as much as 75 Mbps of which could be delivered
to each customer. In a typical scenario, customers are provided various types of services
distinguished from each other by the bandwidths they offer. The network operators
also oversubscribe their network to various degrees to achieve better cost amortization.
Given such a diverse set of scenarios, Table 15.3 provides the cost per customer for
deploying WiMAX services for various types of broadband services and under various
oversubscription scenarios.
