The evolution of the new M2M/IoT paradigm suggests new applications in several fields. However, the unique characteristics of M2M communications pose different challenges in terms of connectivity and capacity with respect to the conventional telecommunications networks. In particular, the harmful locations where IoT devices could be deployed and the massive number of the devices to be connected require...
This paper identifies the market changes following the technological switch from 3G to 4G in the Indonesian market. The primary data were obtained by conducting a market survey in April-May 2017. A set of questionnaires was developed to compare subscribers’ activities between 3G and 4G service utilization in terms of two activity clusters. The first cluster consists of 14 conventional activities,...
In this paper, we revisit the radio network energy performance evaluation methodology, commonly known as E3F, that was developed in the European EARTH project during 2010–2011. We propose updates to the large-scale deployment and long-term traffic models in order to reflect the situation in a 5G time frame, and also an improvement in the sense that the baseline network is dimensioned to exactly meet...
Proponents of satellite use of C-Band have presented economic and technical studies suggesting the band be preserved exclusively for satellite use. Proponents of using the band to support small cell mobile broadband systems have also presented various technical and economic arguments supporting an allocation to this service. These argument are being heard in the International Telecommunications Union...
In October 2012 Croatia has assigned the frequency band 790–862 MHz (Digital Dividend) to two mobile operators (2 times 20 MHz). The introduction of mobile services in the Digital Dividend band can cause interference to the reception of existing DVB-T (Digital Video Broadcasting — Terrestrial) networks operating on adjacent channels. This paper describes the expected interference scenarios of LTE...
In this paper, a generalized model is proposed to analyze the impact of propagation environment and velocity on the handover performance of user equipment (UE) for long term evolution (LTE) systems. An adaptive time window is defined within the generalized model, to provide additional flexibility to perform handover procedure over conventional reference signal received power (RSRP) and reference signal...
