“…The authors in [9][10][11] tackled the network economics of the network evolution from 3G (third generation) to wireless broadband. The authors in [12][13][14][15] analyzed the hierarchical structure of the wireless network economics. Many methodologies and algorithms have been proposed for optimizing the cost of a wireless network as for example in [16][17][18].…”

This paper provides the economical tradeoffs for supporting multiple services over an OFDMA cellular network. These tradeoffs are related to two conflicting goals: (1) maximizing coverage so as to lower the system cost; and (2) maximizing the number of end users so as to maximize revenues. This problem is formulated in terms of coverage spectral efficiency, which directly determines the system capacity. We will analyze how the coverage geometry and the service requirements affect the coverage spectral efficiency, which determines the revenue generation. This paper also shows how the channel impairments (shadow fading, fast fading, and co-channel inference) affect the economics of the OFDMA system.
