Mobile phones have become essential part of our life in the last 15 years. All mobile phones have a lot of common features, but their individual style or design, and special functions make these devices salable. However there is an important accessory - the charger - which does the same task to reach the same goal from the beginning, but on a wide range of implementation. A few years ago, GSMA (in...
Energy consumption and CO2 emissions have recently become topics of particular interest across the cellular telecommunication industry. This situation is moving this industry towards the introduction of renewable sources of energy, such as solar energy, wind energy, etc. for the energy supply to their networks. These solutions are environmentally friendly and technically proven, but when it comes...
The rapid growth of telecommunication has raised the mobility concept & demand among users. With mobile in hand user finishes its maximum work of different nature in minimum amount of time. This increases the work efficiency of users in overall aspect. This change is effective if and only if service providers provide qualitative cellular services. User is more and more demanding now a days...
This paper presents a novel mechanism which increases mobile terminal battery performance. It supports a cell reselection algorithm which decides on which cell, user equipment (UE) is camped on when in idle mode (there is no active radio connection with a mobile network). Study is based on real 3G UTRA network measurements. Authors propose a technique to reduce UE current consumption in idle mode...
There is considerable interest in the industry in smart phones today. Even in a down economy, sales of smart phones are rising and promising to shake up the future of mobile communication. The players involved are seeking ways to differentiate themselves in this market space, and improved energy management is a key area of focus. This paper focuses on smart phone power.
Pervasive healthcare technology is one of the methods for meeting the challenges of an aging population in many western world countries, as well as an expected major shortage of healthcare personnel. The OpenCare Project is an open source infrastructure framework, designed to be used by researchers and corporate developers for developing experimental assistive living prototypes. The Personal Communication...
Consider an uplink cellular network shared by a finite number of mobile users with limited batteries. Whenever the battery drains out, the user pays a fixed price to recharge the battery. Users, assumed to have always traffic to send, control their transmission power in a noncooperative way. The novelty of our model is in considering the dynamic game in which the transmission power of a player may...
The risk associated with using a mobile phone in a Category 3 (Zone 2) Explosive Gas Atmosphere is evaluated. Experimental trials were performed on a representative sample of commercial grade mobile phones using the guidelines provided in The Instrumentation, Systems, and Automation Society's ISA-RP12.12.03-2002 "Recommended Practice for Portable Electronic Products Suitable for Use in Class...
In this paper we discuss performance results of a novel real-time closed-loop power amplifier (PA) linearization technique that has originally been proposed by Ahmed and Li. The novel approach performs on-the-fly prediction and measurement of the PA AM/AM and AM/PM non-linearity, stores such non-linear characteristics and calculates their inverse functions in order to pre-distort the base-band amplitude...
