Growing green with improved profit through reduced power consumption in LTE networks

Long Term Evolution (LTE) is well known 4G technology which promises higher data rates. Due to advancements in smart phones and new applications, the user's data requirements have significantly increased. The data hungry users engage radio resources over long periods of time thus resulting into higher energy consumption by Base stations (BSs). Increased energy consumption due to higher data rates directly increases Operational Expenditure (OPEX) thereby ensuing economic and environmental benefits, i.e. profitability and Global Warming. This paper presents detailed performance analysis of our novel joint resources block switching off and bandwidth expansion based energy saving scheme. Our proposed scheme offers 29% energy saving thus results in to decreased CO2 emissions (approximately 1.12 tonnes/ BS) and reduced OPEX thereby enabling mobile vendors to have high profile in Growing Green and help them to improve both environmental and economic aspects. Vendors could enjoy increased profit and stay Green through usage of our energy saving scheme.
