Today, Communication has increasing influence on our Daily life. Wireless data Communication services allow people to access the data Network without a physical Connection. This work Studying Wireless Local Area Network WLAN features and describing all technologies and standard necessary to operate this network. This work aims also at comprehensive investigation of wireless network including wireless Local Area Networks implementation and performance analysis. Testing WLAN performance through some practical measurement such as site surveying in different locations, finally measuring the strength of the signals different locations in the coverage area, test results can be used in order to enhance the network performance.

Denna rapport jämför ett kommersiellt site survey-verktyg med ett open sourcealternativ. En site survey är processen att planera och implementera ett trådlöstnätverk. Det är viktigt för att undvika problem med täckning, störningar samtplacering och konfigurering av accesspunkter. För att göra jämförelsen har en metod utvecklats för att jämföra site survey-verktyg. Metoden tar upp och jämför olika kriterier i form av verktygens förmåga att hantera signalstyrka, störningar, quality of service, manuella site surveys, virtuella site surveys, dokumentering av resultat samt verktygens förmåga att underlätta vid placering och konfigurering av accesspunkter. Förutom detta tas även mjukvarornas gränssnitt och användarvänlighet upp. Metoden skulle dock kunna utökas ytterligare för att innefatta t ex säkerhet, inlärningstid och support, för att på så sätt bidra till en bättre jämförelse.De verktyg som har jämförts är open source-mjukvaran Kismet och den kommersiella mjukvaran InterpretAir. InterpretAir har visat sig ha en bättre funktionalitet på alla punkter och anses därför vara den mest lämpliga mjukvaran vid en site survey. Detta kan dock ha berott på att Kismet, trots att det utsetts till det lämpligaste open sourcealternativet, inte är ett renodlat site survey-verktyg och därför inte har samma fokus på just denna funktionalitet.

This thesis studies people’s sensory perceptions of historic architecture, exploring the physical triggers for such experience, and connecting these with what can and should be maintained through building conservation. Sensory design is a developing field in architecture. The research argues that this approach can inform people’s understanding of the architectural experience of historic buildings, which in current discourse are predominantly considered for their associated ‘cultural significances’. People’s affinity to (historic) buildings is initiated by a response through the senses. This research advocates that establishing the triggers for such sensory response should be the main focus of the initial assessment of a building for conservation. From the review of changing approaches to building conservation, and exploration of sensory perception and sensory design, the research concludes people’s experiential perceptions have not been structurally considered in the appraisal of historic buildings. The methodology entailed the empirical development of a suitable assessment format, through performing initial on-site surveys that generated data to be added to those of a final sensory assessment, covering three buildings. Buildings were assessed according to Gibson’s sensory systems of visual, auditory, haptic, olfactory/gustatory and orientational perception, as well as with a comprehensive multisensory focus. Evidence from the data retrieved through this research indicates that the sensory assessment is a useful, informative and exciting addition to any architectural survey in building conservation practice. Such rich information will provide guidance and clarity to decision processes, to assist in retaining the affinity as the building’s physical relevance for the future. The research makes an original contribution to knowledge through the combination of two areas of study; through the application of sensory perception to understand historic buildings; and, in demonstrating that a sensory assessment has true potential as a suitable approach to the issue in practice.

This thesis deals with mapping and reengineering of existing wifi network. The goal is an analysis of the measured characteristics with the program Ekahau Site Survey. On its basis is designed new solution. Own work is also an financial assessment of the solution.

A administração dos recursos educacionais nas instituições de ensino tem se tornado um problema logístico mediante o aumento da demanda pela utilização de salas, para aulas expositivas e laboratórios, para aulas práticas com recursos computacionais. Este trabalho apresenta um estudo para implementação de uma rede sem fio no padrão IEEE 802.11 em ambiente educacional, flexibilizando os recursos de sala de aula e laboratório de forma que em uma estrutura predial única as salas possam ser montadas como laboratórios ou salas de aula em função da necessidade. Para realizar esse estudo, foram realizados testes de comunicação entre os dispositivos, em um ambiente educacional utilizando recursos e equipamentos com a capacidade de analisar o sinal de propagação do radio no ambiente. Verificou-se que o estudo do ambiente em função da propagação do sinal da rede sem fio, garante eficiência na comunicação de dados entre os recursos computacionais e a rede sem fio garantindo a eficiência do ambiente proposto e economia na sua implementação. / The administration of educational resources in educational institutions has become a logistical problem by increasing the demand for use of rooms, for lectures and laboratories, for practical classes with computing resources. This work presents a study for the design and implementation of a standard IEEE 802.11 wireless network in the educational environment, making the classroom and laboratory resources flexible, in a manner that in a single building structure the rooms can be mounted as classrooms or laboratories depending on the need. To carry out this study, tests were performed between communication devices in an educational environment using resources and equipment with the ability to analyze the radio signal propagation in the environment. It was found that the study of the environment depending on the signal propagation of the wireless network ensures greater efficiency in data communication between computing resources and wireless network, ensuring the efficiency of the proposed environment and economy in implementation.

De flesta av Sveriges kommuner har ett mål där de strävar efter att bygga ett hållbart samhälle, vilket innebär att man utnyttjar den befintliga infrastrukturen. Målet med detta är att dra nytta av de obebyggda områdena i stadsbilden genom att bygga nytt. Eftersom de tysta sidorna av byggnaderna ska ligga på en ljudnivå under 45 dB(A) har det här examensarbetet behandlat de möjliga lösningar som kan tillämpas vid bullerdämpning. En platsinventering har utförts där de olika förutsättningarna har studerats, och där resultaten av studierna har granskats med syfte till att planera en vision. Nyckelord: Bullerdämpning, bostadsutformning, platsinventering / Most Swedish municipalities have a goal which they strive to build a sustainable society, which involves the use of the infrastructure. The aim of this is to take advantage of the undeveloped areas of the urban landscape by building new buildings. Since the quiet sides of the buildings shall be at a noise level below 45dB(A), this diploma work addressed the possible solutions that can be applied in noise attenuation. A site survey has been performed there the different conditions have been studied, where the results of the studies have been reviewed in order to plan a vision. Keywords : Noise attenuation, residential design, site survey

Traditional wireless site surveys produce a heat-map of link strength or quality over a target area, usually on the ground plane. In recent years research has gone into using aerial drones in network attack and surveillance, making three dimensional awareness of wireless coverage areas of interest. A multi-rotor drone and data collection module were built and tested as part of this research. Site assessments were conducted both in open space and near structures. Collected data was interpolated across the target area, and visualized as points and contours. These visualizations were exported to a Keyhole Markup Language (KML) for visualization in context. Resulting visualizations proved to be beneficial in identifying the coverage area of both authorized and rogue access points.
