To meet the global challenge of reducing greenhouse gas emissions and the exponentially growing data traffic, green design of cellular network is becoming a urgent issue for wireless network operators. In this paper, we first discuss the performance evaluation methodology for future wireless networks from the viewpoint of five basic metrics, i.e., throughput, power consumption, deployment cost, bandwidth, and latency. We then study the fundamental tradeoffs from Shannon's perspective based on the five metrics. Furthermore, we extend the tradeoff relation from point-to-point link to a heterogeneous network scenario taking into account realistic base station power model. Our study provides useful insights for the evaluation, modeling and deployment of future green wireless networks.
