The Power of Wireless Cloud: An Analysis of the Impact on Energy Consumption of the Growing Popularity of Accessing Cloud Services via Wireless Devices
This white paper, The Power of Wireless Cloud, addresses the question of energy consumption associated with wireless devices, such as laptops, tablets and smartphones, when accessing cloud services. The use of wireless access technologies will increase as cloud services expand from the enterprise market to also providing consumer services.
The writing of this document was motivated by the
explosive growth we are now seeing in wireless access
to cloud services, and a need to understand the energy
implications of using wireless to access cloud services as these services expand into the consumer market. Until
the publication of this white paper, discussion of energy consumption by cloud services almost exclusively focused on corporate (enterprise) cloud services accessed via wired connections. With the evolution toward wireless access and the growth in consumer cloud services, in this white paper CEET extends this debate to include this broader cloud ecosystem.
The paper shows that wireless access via 4G LTE mobile
networks and local home WiFi consumes more energy
per bit of data transferred than public WiFi networks.
Importantly, the paper also shows that when considering
end-to-end wireless cloud services, a larger fraction of the energy is spent in the wireless access than the data centre.
