The complexity of wireless networks requires a careful design, especially related to bandwidth and energy efficiency. Bandwidth efficiency is very important parameter, because it relates to frequency spectrum, which is a natural limited resource. The cognitive radio has been proposed as the future technology to meet the ever increasing demand of the radio spectrum by allocating the spectrum dynamically to allow unlicensed access on noninterfering basis. The digital dividend of 700MHz band (mainly used by TV broadcast services) opens the door for cognitive radio applications due to its excellent propagation characteristics compared to GSM 1800 MHz, 2.1 GHz or 2.5 GHz bands. In cognitive radio, spectrum sensing is the fundamental problem. In this paper we are analyzing the performance of spectrum sensing algorithms; energy detection and covariance absolute value utilizing TV white space for IEEE 802.11 af standard.

In AmI, technologies are deployed to make computers disappear in the background, while the human user moves into the foreground in complete control of the augmented en-vironment. AmI is a user-centric paradigm, it supports a variety of artificial intelligence methods and works pervasively, no intrusively, and transparently to aid the user. AmI supports and promotes interdisciplinary research en-compassing the technological, scientific and artistic fields creating a virtual support for embedded and distributed intelligence. In this paper authors are looking for possibilities to implement AmI as a way for saving energy in the construction industry, especially in buildings. AmI combines ICT and sensor technologies and enables monitoring, controlling and management of using energy in buildings and becomes key factor of energy efficiency in the construction industry.

Results of monitoring and optimization are shown. In our case optimization is done by DAO subsystem. We compare results of two Operators with the same goal to maximize service availability with minimum decrease of service characteristics, specially speed in downstream. APM has purpose for monitoring of all performances of BB system as well as interdependency of lines. APM monitoring and optimization of line parameters is based on changing of End User Profiles and using line testing mechanism integrated in DSLAM devices. APM is designed around a selection of configurable batch jobs that store vital Line Test (SELT and Loop Diagnostic) and DSL-link parameters in the APM database. By selecting the appropriate view, it is possible to follow and understand faulty behaviour in detail. APM is also equipped with a real-time view that is essential when troubleshooting on a per-line basis or when re-configuring a DSL link online. Support for equipment/DSLAM of other vendors than Ericsson is also implemented in APM. APM offers several tools that are designed to solve different problems in a DSL-based network.

However, a problem of today's world is population aging. Over last decades the number of older people has been increasing. The goal of many researches is to enable elderly people to live independently. The ambient assisted living encompasses technical systems, infrastructures, and services to support elderly people in their daily routine and to allow an independent and safe lifestyle as long as possible. One of those projects is eWALL project. IoT is a concept that is used in these projects and it represents the connections between humans and smart objects that are part of this environments. In these kinds of smart environments, different technologies are used for communication. These technologies are: Wi-Fi, Bluetooth, Bluetooth Low Energy and ZigBee. The goal of this work is to show possible problems in coexistence of above mentioned technologies. Also, cognitive radio is considered as a soluti...

Software uses radio propagation modelling to precalculate received signal through the whole network and stores this information. This data is recalled when a positioning request is received and used to create a probability map for mobile phone position. The most likely mobile phone position is calculated from this map using averaging and statistical methods over several base station measurements and over a short time period. Positioning accuracy is discussed and current improvement plans are presented.

In this paper we present eWALL, an innovative open-source eHealth platform that aims to address these challenges by means of an advanced cloud-based infrastructure. eWALL is designed in an innovative manner and achieved technical breakthroughs in eHealth platforms, while prioritizing user and market needs that are often abandoned and are the major reason for technically sound solutions that fail. We consider this as an opportunity and we aim to change the eHealth systems' experience for older adults and break the barriers for the penetration of ICT solutions.
