Green hybrid Fi-Wi LAN

Enterprise WLANs encompassing supernumerary Access Points (APs) are being used to provide capacity to indoor environments. The approach of over dimensioned deployment of APs to meet the capacity needs of users at critical time points are advocated without little concern towards the important issue of power wastage. For a sustainable greener environment the issue of power saving in such enterprise WLANs has to be integrated in our present day design. Hybrid Fiber-Wireless (Fi-Wi) LAN is envisioned as the evolution of enterprise WLAN which can help us enormously to reduce the power wastage while meeting the demands of the indoor users. In this paper, we propose a hybrid Fi-Wi LAN architecture based On Demand Strategy which results in massive power saving (approximately 60%) by switching of APs or Cell Access Nodes (CANs) based on user demand estimation while maintaining coverage throughout the whole cell area.
