Title
In the wikipedia definition of ubiquitous computing (or ubicomp) is a term describing the concept of integrating computation into the environment, rather than having computers which are distinct objects. Thus ubiquitous is meaning to integrate computer as well as all about the wireless technology into our livings space anytime, anywhere. So in this text its meaning is that we explore wireless technology (wlan) as ubiquitous experience.

Abstract
Investigation into an understanding of wlan-networking and its influences on living space
In the wireless technologies the invisible and visible exist simultaneously. It influences our living space, time, and feelings. This paper is an exploration into the structure of Wlan and the communication between access point and client. It shows how simple the alleged private area (local area network) can be extended and intercepted. Perhaps with a Wlan it is simpler to communicate between each other and to create social networks. But there are not only positive aspects and as Brucker Cohen said it is important to keep “Accessibility” in mind. Does it mean that we are “locked out” if we don’t participate in a Wlan? Can we avoid the control by such a network?

The social environment of ubiquitous technologies which we are experiencing in everyday life is increasingly becoming complicated. It cannot be simply understood as the relationship between users and tools anymore. If the new technology given to us is understood just as a comfortable mechanical tool, without conceiving the connection between the human and the computer, it could be difficult to recognize effective social transforming and flows in the ubiquitous environment. The private area can be no longer clearly distinguished from public area in times when we are getting used to smart lifestyle technologies like mobile phones, Wlan, GPS, RFID and smart house systems. In this case we sometimes forget the importance of the individual plays in ubiquitous communication and we raise questions about tolerance, responsibility and freedom between the general public and the individual.

According to investigations into networking, knowledge and the digital age by the students at the University of Prince Edward Island following points can be stated:
-The value of a network increases exponentially as new members are added.
- Internet working empowers individuals and creates decentralism.
- The web codifies and trains all knowledge in its vast network of distributed links.
- Sharing this knowledge enhances communication.

The wireless or radio technology can be also characterized as mobile, portable, ubiquitous and affordable. The very important characteristic is that radio waves are enhanced by signals passing through the air rather than through strands of copper or optical fiber. Armin Medosch argues about the technology of Wlan that it provides a possibility about self-communication-infrastructures. The technology makes it possible to develop own communication infrastructures and to jump over the "last mile" which is the connection from the household to provider or telephone switching centre. Therefore Wlan technology takes two possible types of infrastructure: Peer-to-peer or ad-hoc mode, and the so called infrastructure mode. As a consequence we can use a more free communication method without so called control-centers. But self-organisation-network will be more and more required consideration and perception of the free network.

The problem of ubicomp systems is that everything is becoming computerised. We have absolutely no idea where ubiquitous content control mechanisms will lead us. Since the Wi-Fi technologies have been emerging in the downtown areas where houses are close together some people have been spied by their neighbours. In companies most workers have been felt monitored after a mobile, GPS technology emerged. For instance a firm was monitoring the workers through a service of mobile phones called “seek out friends”. The matter of surveillance in a smart mobility world has already emerged as a major social concern surrounding ubiquitous public awareness. Protest of now familiar video surveillance and data tracking technologies is expanding to address the types of public and private monitoring, as well as civil interventions, enabled by hundreds of thousands of invisible, mobile computers, including RFID tags. Regardless, people are required to create awareness in an age of increased surveillance, that hacking can be a vital countermeasure and a commendable act of self-defense to discover the immaterial virtuality and the qualities of the information of new technologies.

Abstact
The terminology ubiquitous technologies concerns not only simply wireless technologies, as I equally want to show that a small beginning becomes the initiator of a big change. The fact is that ubiquitous technologies in the western computer world means access without directly visible connection, and additionally it is including devices, which can react on an invisible computer-controlled level, as there are GPS, Location Based Service, RFID, and Smart House. It will be everywhere or even is already, since we hardly can see it, and we are getting inconspicuously used to it. Because it is invisible we do no longer perceive these obvious changes transforming our everyday world into a remote controlled scenario.

Description
“Ubiquitous experience” is an interactive installation that represents two views of visible WLAN in the real space and the virtual space so that people can conceive invisible WLAN technology and the transformations occurring in everyday life. In order to demonstrate the invisible processes hiding behind a wireless local area network at first the three-dimensional expansions must be represented.

To show the relation between the virtual website visualization and the real world I will create a supportive room-installation. The installation will be a light-installation and represent the quality of the real WLAN-Area through a light signal. I will arrange about 1600 LED with 18 small WIFI-Scanners all over the room, which will give the adequate light signals. The visitors are able to recognize on the basis of these light signals the WLAN quality, and can affect the signal with an interfering transmitter which is built into a small vacuum cleaner. At the same time the website on the monitor will be changed. In short, if one comes near to a WIFI-Scanner with the transmitter, the light will disappear or being changed into another color (red) and some regions of the website will be distorted. The interfering transmitter is a strong but useless signal like a microwave which can disturb the WLAN signal and make it unavailable for a moment. It is built in the vacuum cleaner so that it represents now a kind of “cleaning device” for WLAN.
