The article highlights the issues related with the creation of "Smart" cabinet of physics based on microelectronics at a technical college. In fact, the "Smart" cabinet of physics is a creative space created by the students and tutors of the educational institution. Such "Smart" cabinet of physics is a "smart" educational environment that is fully automated and can be operated in three modes: "standard", "automatic", "automatic energy saving". The control of the cabinet devices is realized from a smartphone, PC and remote control. The cabinet is equipped with variety of sensors, indicators, electronic components based on Arduino UNO, MEGA, WiFi module ESP8266-12E.The indexes taken from the built-in sensors and indicators of the "Smart" cabinet are used for supplying information about the microclimate of the cabinet, for demonstrations at lectures and laboratory works in physics. The developed "Smart" cabinet of physics consists of three modules: "informational", "executive" and "demonstrational". The microcontroller ATMEL controls each module. The informational module is located in the stand "Physical basics of robotics", and the demonstrational module can be removed and used for demonstrations from the following sections: mechanics, molecular physics, electrodynamics, optics. Various sensors and components of the open-source programming platform Arduino conveniently and quickly connect to the demonstrational module (with the help of a flexible mounting board). Sensors of the "Smart" cabinet of physics give an opportunity to monitor the environment of the cabinet and outside it (temperature, humidity, pressure, illumination, level of carbon dioxide and other gases in the air),as well as to realize remote control of peripheral devices: TV, projector, lamps, sockets, curtains. All three modules connect to the wireless local area network by the topology of the "star" by means of radio communication based on the corresponding modules. The main module in it is the executive one, which has access to the INTERNET. The acquirement of the instrumental, technical, and software tools should become the main part of the system of training in a technical educational institution. The research deals with the issue of creating "Smart" cabinet of physics in a technical college.

SMKN 5 Batam City is an educational institution located in Kavling Bukit Kamboja, Sungai Pelunggut, Kec, Sagulung, Batam City, Riau Islands. The availability of network infrastructure to be institutionalized by education will expedite the educational process including internet network services at SMKN 5 Batam City. The networks used in SMKN 5 Kota Batam are the Local Area Network (LAN) and Wireless Local Area Network (WLAN). Batam City Vocational School 5 has 82 PCs (Personal Computers) connected to the network and Access Points as access to the hotspot network, which uses an indie home ISP with a bandwidth capacity of 100Mbps and 5Mbps using an astinet ISP. Problems that occur on the internet network at SMKN 5 Kota Batam, do not yet have an allocation of bandwidth distribution for network users, causing unstable and uninterrupted network access. Therefore there must be proper bandwidth management controls, implementing bandwidth management and optimizing security authentication. So that the available bandwidth can be used fairly, by applying the queue method. And from the tests carried out, authentication of security and bandwidth management using the tree queue method, fair and even bandwidth can be used as well as the tree queue method proven to be able to use bandwidth both for downloading and downloading. uploaded.

This paper presents a novel compact printed monopole ultra-wideband (UWB) antenna featured with the band notch. The proposed antenna consists of a two-step beveled radiant patch and a truncated ground plane, which can provide a good impedance matching from 3.1 GHz to 10.6 GHz. In order to generate the band-notched characteristics, two symmetrical slots are embedded along with the microstrip feeding line, resulting in a band notch from 5.05 GHz to 5.85 GHz. Accordingly, the mutual electromagnetic interference between the UWB and wireless local area network (WLAN) radio communication systems can be eliminated. In addition, it is shown how the slots integrated on the ground plane improve the radiation patterns. The experimental measurements are found to be in good agreement with the numerical simulations.

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.
