The daily, weekly, and yearly traffic variations and traffic growth as well as energy efficiency strategies based on elastic optical networks, sleep mode and grooming strategies represent a good en

We analyze the implications of integrating the cooling system of a building with the cooling system of electronic equipment and study the effects when applied to AT&Ts 5ESS(TM) digital switch.

With the rollout of LTE networks the energy consumption of wireless networks will further increase.

We propose an alternative design for paging in next generation networks, and investigate its potential for increasing the energy efficiency of base stations.

Abstract—As the mobile traffic is expected to continue its exponential growth in the near future, energy efficiency has gradually become a must criterion for wireless network design.

We design a model of wireless terminals obtained from a Poisson point process with support in an embedded fractal map.

An analysis of the energy savings is presented when taking into account a complete traffic model for a one-year time period.

In wireless access networks the traffic load varies strongly along a day and efficient concepts to adapt the power consumption of LTE macro base stations to the required traffic load are currently

Traditionally mobile communication networks have been designed for maximum throughput and maximum spectral efficiency. With the introduction of new access technologies (e.g.

The daily traffic variation over time requires dimensioning of base stations for high data transmission peaks.
