To reduce the number of inter-disturb access points and the interference among access points in same channel, with research on interference issus and channel assignment algorithms of wireless local area network, a scheme suitable for centralized wireless local area network was proposed aiming to minimize the total interference among access points, which comprehensively considerate the number of neighbor and the received power. And then the algorithm with cases was simulated and analyzed, the result of NS2 simulation indicated that the algorithm was simple, effective and feasible, which could realize dynamic adjustment to the wireless LAN RF channel and had a better load balance effect among non-overlapping channels.

This article discusses the stages of development, characteristics of a wireless local area network Wi-Fi, options for its topology and equipment used. Currently, there are such different types of wireless networks as Wireless Wide Area Network, Wireless Metropolitan Area Networks (Wireless Neighborhood Area Network), Wireless Local Area Network, Wireless Personal Area Network. Each of the listed wireless networks has its own specific range and application. Wireless LAN Wi-Fi refers to the Wireless Local Area Network. The first wireless LAN standard, Wi-Fi, was approved in 1997. From the moment of their appearance to the present day, the following standards of this network have appeared: 802.11a, 802.11b, 802.11g, 802.11n, 802.11ac, 802.11ad, 802.11ax. For each standard, the speeds and frequency ranges at which the data transmission was carried out are indicated, and the technologies on which they are built are described. Wireless LAN Wi-Fi has three topologies: 1) Ad-Hoc (point-to-point) or Independent Basic Service Set; 2) Basic Service Set (“client / server”) and 3) Extended Service Set (“extended service areas”). To build a Wi-Fi network, network adapters, access points, routers, ADSL modems, Wi-Fi phones, Wi-Fi antennas, Wi-Fi repeaters are used. Wi-Fi adapters are used by devices that do not have a built-in Wi-Fi module. Wi-Fi access points are designed for organizing wireless access within a local network. Wi-Fi routers are designed to route traffic on a computer network. ADSL modems are used to access the Internet over a telephone line. Wi-Fi repeaters are used to expand the coverage of a wireless network using already installed equipment. Wi-Fi phones are wireless IP phones. Wi-Fi antennas are used to extend the range of a wireless network.

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.

AbstractAs indoor positioning provides particular challenges due to the unavailability of GPS signals, various systems such as ultra-wideband (UWB), radio frequency identification (RFID), ultrasound, and wireless local area network (WLAN) have been proposed in recent years. Some of these technologies are currently being marketed and some are still being developed. UWB technology allows for higher precision while also reducing power consumption. Hence, the underground automation and localization systems can use this technology for more accuracy and robustness. This article discusses new robust UWB modules used for underground positioning and collision avoidance with regard to human safety in underground mining operations.
