Summaries of three conference Keynotes are provided: "Modern academia: teaching, research, development, patents and standards" by Uday B. Desai "Vehicle communication: a future telecommunication market" by Tadao Saito; and "Future of communications - the individual user experience" by Detlev Otto.
The paper analyses the performance of wireless networks working over unlicensed frequency ranges, making use of diversity transmission systems, as an effective means to increase outdoor coverage capabilities in rural scenarios. To this purpose, a network has been designed and realized, providing coverage to a wide rural area in the hills of Piedmont, a region located in North-Western Italy. Once constructed,...
RFID System suffers from limited address space and local mobility. Moreover, it is a monopoly business with few vendors, which are trying to dominate the market with proprietary standard of RFID reader. The proposed system will replace the expensive RFID reader with cheap Wireless Network Interface Card (WNIC). For the purpose, an innovative scheme for RFID tagging system is introduced which will...
This paper presents an ICT solution to overcome the problem of water dispersion in water distribution networks. Leakage prevention and breaks identification in water distribution networks are fundamental for an adequate use of natural resources. Nowadays, all over the world, water wasting along the distribution path reaches untenable percentages (up to 80 % in some regions). Since the pipes are buried...
In this paper an adaptive resource allocation algorithm in OFDMA based cognitive radio (CR) system is proposed that not only meets the quality of service (QoS) of real-time (RT) services but also increases the dynamic capacity of the system. In contrast to existing algorithms for multi-user OFDM systems which are unable to guarantee maximum sum data rate when applied to CR system in real-time, the...
While modern telecommunications are becoming ever more useful and even necessary in everyday life, not all groups of people are equally capable of using them. Due to inevitable demographic changes the elderly are growing in number, yet they are not very well served by user interfaces for the various telecommunications tools. The prime target group for our proposed technology is people with cognitive...
This paper presents ultra wide band circular fractal antenna. The antenna has been fed with coplanar waveguide (CPW) feed. This fractal antenna has been designed and fabricated on FR4 substrate εr = 4.3 and thickness h = 1.53 mm with initial diameter of solid circular disc 15 mm. The experimental result of circular fractal antenna exhibits the ultra wide band (UWB) characteristic from 3.295 GHz to...
Maths is presently regarded as the key driver that underpins Science, Education and Technology (SET) skills. In spite of significant studies, investment and efforts, math skills and widespread enthusiasm for SET remain elusive. In South Africa's disadvantaged communities, poor quality maths teaching and poor maths performance, both legacies of past political engineering, further fuel marginalization...
This paper presents the design of an inscribed square circular fractal antenna with notch having adjustable frequency characteristics. The position and width of the notch band can be adjusted in the entire operating band. A prototype of the antenna has been designed on FR4 substrate dielectric constant 4.3 and thickness h = 1.53 mm with a U-shape slot in coplanar waveguide feed of length L = 11 mm...
This work illustrates the methodological approach followed in the Province of Orellana, Eastern Ecuador, for the realization of a telecommunication network infrastructure between the capital of the Province, the city of Puerto Francisco de Orellana (also known as El Coca), and some peripheral communities located in the surrounding of the tropical moist forest. The project has been implemented in one...
The government of Japan has announced the new ICT policy in June 2010. One of the points of the new policy is to start the 3D motion image content market in order to create new key industries in the near future as 3D motion image content will become most powerful media for CGM (Consumer Generated Media). In order to activate 3D motion image content industries, the development of an effective and simple...
This paper presents a self organized spectrum chunk selection algorithm in order to minimize the mutual inter-cell interference among Home Node Bs (HeNBs), aiming to improve the system throughput performance compared to the existing frequency reuse one scheme. The proposed algorithm is useful in Local Area (LA) deployment of the Long Term Evolution-Advanced (LTE-A) systems, where the HeNBs are expected...
The very nature of Radio Frequency (RF) technology makes Wireless LANs (WLANs) open to a variety of unique attacks. Most of these RF-related attacks begin as exploits of Layer 1 (Physical - PHY) & Layer 2 (Media Access Control - MAC) of the 802.11 specification, and then build into a wide array of more advanced assaults, including Denial of Service (DOS) attacks. In Intelligent Jamming the jammer...
