Enabling Backoff and Eliminating Redundant Idle Period for Medium Access in LTE-U
2017
To address the burgeoning demand for mobile data, 3GPP is actively studying the capability of operating LTE in the unlicensed band, referred to as LTE-U. One of the main challenges of this approach is to maintain better coexistence between WiFi and LTE-U devices. To enable the coexistence, the listen before talk (LBT) principle has been adopted for LTE-U medium access with two flavors of mechanisms, i.e., load based equipment (LBE) and frame based equipment (FBE) access. In this paper, we consider the FBE mechanism and enhance its performance by introducing a backoff procedure for LTE devices. We investigate the original FBE mechanism defined by 3GPP and the enhanced FBE (E- FBE) mechanism fr…
A comparative study of mobile messaging services acceptance to participate in television programmes
2010
PurposeThe purpose of this paper is to analyse key drivers of consumer acceptance of short messaging services (SMS) to participate in TV programmes.Design/methodology/approachThe technology acceptance model (TAM) and the theory of planned behaviour (TPB) have been integrated for the determinants of the acceptance of mobile data services incorporating variables regarding consumer‐media interaction (perceived value and affinity). The model has been tested using structural equation modelling.FindingsPerceived value, attitude and affinity towards television (TV) programmes determine SMS acceptance to participate in TV programmes in Spain. In contrast, subjective norm, perceived value and attitu…
Development of Waste Collection Model Using Mobile Phone Data: A Case Study in Latvia
2020
In organizing household waste management and controlling waste collection and disposal, it is necessary to minimise risks to the environment and human health and, where possible, ensure that waste is recycled and returned to the economic cycle. Different models are being applied to increase waste collection management efficiency, but in recent years, the mobile phone data is widely used to solve various application problems. The research objective is to develop a waste collection model, which responds to the population’s current demands and allows planning waste container loading, based on mobile phone data statistics. The developed approach, techniques and data model can be used for waste …
Mobile Apps and Social Media
2017
1The increasing penetration of smartphones among global population, especially among youth and children, has define a mobile and interactive media use without any precedent. A global connected world is the context in where our offspring are developing self-competences in media literacy because they manage technological devices at very early ages. This context is the state of affairs of this article in which we present two different steps: firstly, a theoretical study, showing the impact of mobile devices, focusing on smartphones and mobile applications where the question arisen is: What are children and young doing while online? Media literacy is also described in order to apply its dimensi…
