Energy-efficiency in telecommunications networks: Link-by-link versus end-to-end grooming [PDF]

2010 14th Conference on Optical Network Design and Modeling (ONDM), 2010
The large share of energy consumption in telecommunication networks is expected to shift from access networks to core networks. Estimating the power consumption of core networks is not easy, as they vary a lot in size and topology. Using an exemplary but realistic core network, we estimate its power consumption for both a link-by-link grooming and an ...

Cascaded multiplexed optical link on a telecommunication network for frequency dissemination [PDF]

Opt.Express 18:16849,2010, 2010
We demonstrate a cascaded optical link for ultrastable frequency dissemination comprised of two compensated links of 150 km and a repeater station. Each link includes 114 km of Internet fiber simultaneously carrying data traffic through a dense wavelength division multiplexing technology, and passes through two routing centers of the telecommunication ...

Investigating the Links of Interpersonal Trust in Telecommunications Companies [PDF]

Sustainability, 2018
The purpose of this paper is to determine if there are links between interpersonal trust and competences, relations, and cooperation in Polish telecommunications companies. It examines which factors affect trust in co-workers and managers in sustainable organizations. The paper surveys a sample of 175 employees of telecommunications companies in Poland

Monitoring the COVID-19 epidemic with nationwide telecommunication data [PDF]

, 2021
In response to the novel coronavirus disease (COVID-19), governments have introduced severe policy measures with substantial effects on human behavior. Here, we perform a large-scale, spatio-temporal analysis of human mobility during the COVID-19 epidemic.

Novel mission concepts for polar coverage : An overview of recent developments and possible future applications [PDF]

, 2012
The paper provides a survey of novel mission concepts for continuous, hemispheric polar observation and direct-link polar telecommunications. It is well known that these services cannot be provided by traditional platforms: geostationary satellites do ...

Seeking the links between competition and telecommunications investments

Telecommunications Policy, 2015
This paper empirically analyzes the relationship between competition and investments in the telecommunications industries of OECD countries. The impact of market opening on infrastructure investments is a critical ingredient for regulatory reviews, but the literature findings on this subject are quite mixed.

A Comparative Study of Social Network Classifiers for Predicting Churn in the Telecommunication Industry [PDF]

, 2020
Relational learning in networked data has been shown to be effective in a number of studies. Relational learners, composed of relational classifiers and collective inference methods, enable the inference of nodes in a network given the existence and strength of links to other nodes.

The provision of telecommunications links for the LEP collider [PDF]

Proceedings of the 1989 IEEE Particle Accelerator Conference, . 'Accelerator Science and Technology, 2003
The relatively large physical size of the CERN LEP (Large Electron-Positron) collider complex has resulted in a radically different approach to the provision of the telecommunications links for LEP compared with earlier accelerators. In previous accelerators, telecommunications links in the widest sense (links for voice, data, TV images, special ...

SI-traceable frequency dissemination at 1572.06 nm in a stabilized fiber network with ring topology [PDF]

, 2021
Frequency dissemination in phase-stabilized optical fiber networks for metrological frequency comparisons and precision measurements are promising candidates to overcome the limitations imposed by satellite techniques. However, network constraints restrict the availability of dedicated channels in the commonly-used C-band.
