"Green Radio" in Heterogeneous Wireless Wideband Networks
2008 (English)Conference paper (Refereed)
Heterogeneous networks are an efficient way to support high data rates for non-uniform spatial traffic densities. In this paper we have studied the power consumption of different configurations of heterogeneous wireless networks in an urban environment. The model used is based on simulating the spatial traffic densities with a log-normal distribution, and making Monte-Carlo simulations to estimate the power consumption of different network layouts. We have compared the power consumption of three different network layouts. The power consumption break-even for a macro layer supported by a hotspot layer, compared to a macro cellular layer, is around 25-30 Mbps per square kilometer. At data rates of 100 Mbps per square kilometer, the power consumption of the hotspot supported layout is approximately half of the macro-layer only configuration.
