has an important impact on the number of dropped calls and
is traditionally optimized manually with the help of planning
tools. In this paper, a method for automatically optimizing a
NCL is presented, which consists of an initialization using a selfconfiguration phase, followed by a self-optimization phase that further refines the NCL based on measurements provided by
mobile stations during the network operation. The performance
of the proposed methods is evaluated for different user speeds
and different NCL sizes. Besides, the convergence speed of the
proposed self-optimization method is evaluated. It is shown that
when about 6000 measurements are reported by mobile stations,
the proposed self-optimization method attains a stable maximum
performance about 99% of success rate.

Handover Measurement in Mobile Cellular Networks: Analysis and Applications to LTE

The work is dedicated to network modeling and performance evaluation. The exposition focuses on neighbor cell scanning and addresses its key probabilistic events: (i) suitable handover target found, (ii) service failure, and (iii) scan withdrawal under the interference-limited condition in a multicell system. We derive their expressions and provide a generalized framework for the analysis of handover measurement failure and target cell quality by the best signal quality and minimum duration outage. Results applied to LTE have also shown its effectiveness.

Analog Analogue: U.S. Automotive Radio as Mobile Medium

by Matthew Killmeier

The Mobile Media Reader, eds. Noah Arceneaux and Anandam Kavoori. (New York: Peter Lang, 2012), 40-54.

Automotive radio expressed and complemented dialectically intertwined centrifugal and centripetal tendencies in U.S. society. Its history grounds three more general theses aimed at amplifying historical understanding of mobile media. First, mobile media build upon existing communications linkages, but over time reconfigure them as new communications exchanges. Second, successful mobile content complements the particular characteristics of the mobile medium’s development and cultural usage. Third, mobile media are characterized by mobile privatization, mutually constitutive with segmentation and increasing everyday and aggregate mobility.

Italiani maniaci del cellulare: trascorrono al telefono il 25% del loro tempo

Così, malgrado le notevoli difficoltà economiche, nei primi tre mesi del 2012 è aumentato esponenzialmente l’uso del cellulare. Gli italiani trascorrono circa 4 ore al giorno al telefonino: è quanto emerge da uno studio condotto da SuperMoney (http://www.supermoney.eu/), l’unico portale italiano accreditato da Agcom per i servizi di confronto del campo della telefonia.

L’analisi SuperMoney, condotta sulla base di un campione di 40 mila utenti del portale, compara i dati dell’ultimo trimestre 2011 con quelli dei primi tre mesi 2012. Nel primo trimestre del 2012 si rileva un vero e proprio boom nelle connessioni internet da smartphone. Il tempo di connessione si è allungato del 36 %, arrivando a circa 3 ore e 15 minuti ogni giorno.

In aumento anche il numero di chiamate (+13,19%quelle in uscita, + 3,81% quelle in entrata) e la loro durata. Anche i messaggi crescono: in un solo trimestre sono passasti da 6,5 a 7,3 sms inviati ogni giorno.

Tirando le somme, ogni giorno gli italiani trascorrono circa 37 minuti parlando al cellulare (24 minuti per le chiamate in uscita, 13 minuti per quelle in entrata), circa un quarto d’ora al giorno se ne va inviando sms (ipotizzando di dedicare in media due minuti a ogni messaggio) e per circa 3 ore e un quarto si naviga sul web da cellulare. In totale, a fine giornata, vengono spese 4 ore tra sms, chiamate e navigazione internet: un quarto del nostro tempo da svegli.

Mixing with MXit when you're Mix: Young people, hybrid identity and the mobile phone

This paper explores how the mobile phone fits into their lives and takes on meanings associated with everyday practices related to the hybrid identity of these young people. It is based on qualitative research which included semi-structured individual interviews with 11 young people between the ages of 18 and 24, as well as participant observation and a textual analysis of a popular mobile gossip website at the time of the research, called Outoilet.

Dragging young people down the drain: The mobile phone, gossip mobile website Outoilet and the creation of a mobile ghetto

All the residents here know each other and there is very little privacy, and the mobile phone, during the period of my research, reinforced this lack of privacy through gossip. Such gossip promoted an inward looking collective sociability. As this article demonstrates, subjects of gossip avoided the streets to escape collective surveillance. Outoilet’s explicit sexual language seemed to target those who attempted social mobility by replicating local discourses of respectability and shame. Contrary to findings from other contexts the mobile phone here thus promoted a collective sociability and may have discouraged mobility as well as economic development.

Adultery Technologies

Drawing together a history of writing on love and flirtation, queer theories of intimacy and friendship, and empirical studies of mobile media, I examine how smart phones reflect the vulnerabilities of contemporary relationships. If mobile technologies provide an infrastructure to relieve the tensions inherent in normative coupledom, they also potentially refigure our sense of domesticity's function, and perhaps those remaining links between physical proximity and intimacy.

It strives to address a tussle between the actors involved in a heterogeneous wireless access network. However, as with any market-like institution, it is vital to analyse the Digital Marketplace from the strategic perspective to ensure that all shortcomings are removed prior to implementation. This paper presents some preliminary results of such an analysis.
