The Subject

It is somewhat difficult to motivate students to learn both wired and wireless local area network design because students find the subject technical, dry when delivered in class, and rather boring. This chapter introduces the case of a Web-based tool for class demonstration as well as modelling LAN design. The background of the case is presented and is followed by a review of some existing tools for network simulation and modelling. After introducing the learning theories and concepts (e.g., experiential learning and constructivism) relevant to the tools’ pedagogical value, the chapter describes the architecture and components of WebLan-Designer. The main benefits of using WebLan-Designer are discussed in the light of educational theories, and their validation is supported by a summary of comments received. The chapter concludes with remarks on the strengths and weaknesses of WebLan-Designer and its future development.

Modernization causes the examination process in some educational institutions that are usually done conventionally now start to change to CBT (Computer Based Test). At STMIK Atma Luhur, CBT in the form of a coding test carried out on a computer laboratory was felt to be not effective enough due to a short correction time, as well as the possibility of lossing the students work due to sudden power failure. Collection of jobs using an LAN (Local Area Network) intranet network can not be realized due to the difficult network configuration and requires not a small cost. One solution that can be offered in overcoming the above problem is to create a web-based exam application that is connected to a Wireless Local Area Network (WLAN) intranet network. The system development model and tools used in this study are prototype models and UML (Unified Modeling Language). The proposed application is effective in facilitating and accelerating the process of collecting student answer files from several client computers to a server computer. In addition, the usage of the proposed application allows the lecturer not to correct students' answers in a hurry, so that the scores that are truly objective and can be accounted for are obtained.

Abstract Context.—Health care providers have expressed increasing interest in incorporating digital images of gross pathology specimens and photomicrographs in routine pathology reports. Objective.—To describe the multiple technical and logistical challenges involved in the integration of the various components needed for the development of a system for integrated Web-based viewing, storage, and distribution of digital images in a large health system. Design.—An Oracle version 8.1.6 database was developed to store, index, and deploy pathology digital photographs via our Intranet. The database allows for retrieval of images by patient demographics or by SNOMED code information. Setting.—The Intranet of a large health system accessible from multiple computers located within the medical center and at distant private physician offices. Results.—The images can be viewed using any of the workstations of the health system that have authorized access to our Intranet, using a standard browser or a browser configured with an external viewer or inexpensive plug-in software, such as Prizm 2.0. The images can be printed on paper or transferred to film using a digital film recorder. Digital images can also be displayed at pathology conferences by using wireless local area network (LAN) and secure remote technologies. Conclusions.—The standardization of technologies and the adoption of a Web interface for all our computer systems allows us to distribute digital images from a pathology database to a potentially large group of users distributed in multiple locations throughout a large medical center.

Now a days in Wireless Local Area Networks (WLANs) used in different fields because its well-suited simulator and higher flexibility. The concept of WLAN  with  advanced 5th Generation technologies, related to a Internet-of-Thing (IOT). In this project, representing the Network Simulator (NS-2) used linked-level simulators for Wireless Local Area Networks and still utilized IEEE 802.11g/n/ac with advanced IEEE 802.11ah/af technology. Realization of the whole Wireless Local Area Networking linked-level simulators inspired by the recognized Vienna Long Term Evolution- simulators. As a outcome, this is achieved to link together that simulator to detailed performances of Wireless Local Area Networking with Long Term Evolution, operated in the similar RF bands. From the advanced 5th Generation support cellular networking, such explore is main because different coexistences scenario can arise linking wireless communicating system to the ISM and UHF bands.

Microstrip antenna which designed with dual feeding at 2.4 GHz and 5.8 GHz can meet WLAN (Wireless Local Area Network) application.Antenna fabrication use PCB FR4 double layer with thickness 1.6 mm and dielectric constant value 4.4. The length of patch antenna according to calculation 28.63 mm, but to get needed parameter length of patch should be optimized to 53 mm. After examination, this antenna has VSWR 1.212 at 2.42 GHz and 1.502 at 5.8 GHz, RL -13.94 dB at 2.42 GHz and -20.357 dB at 5.8 GHz, gain of antenna 6.16 dB at 2.42 GHz and 6.91 dB at 5.8 GHz, the radiation pattern is bidirectional. Keywords : microstrip antenna, wireless LAN, dual polarization, single feeding technique
