Метод попереднього планування безпроводової локальної мережі стандарту IEEE 802.11

Abstract

UA: Досліджуються різні підходи планування при проектуванні безпроводової мережі стандарту IEEE 802.11 у приміщеннях. У статті подано формули та розрахунки методом завдання фіксованої кількості користувачів на точку і результати імітаційного проектування мережі Wi-Fi, побудованого на програмі D-Link Wi-Fi Planner Pro.

EN: Examines various approaches of planning in the design of wireless network standard IEEE 802.11 in the premises. The article gives formulas and the calculation method of tasks a fixed number of users on point, and the results of simulation designing Wi-Fi network based on the program D-Link Wi-Fi Planner Pro. The program is designed for the initial analysis of the floor plan with the aim of placing it on the access points Wi-Fi. She focused on the use of the equipment D-Link, to allow for the different room settings, in particular, not only the actual floor space, but the type, material and number of partitions. In addition, D-Link Wi-Fi Planner Pro allows you to conduct calculations similar to automatic access point placement or manual. When the AP placement is very important to determine what materials are made of walls, floors, structural elements and furniture in the room, and had given this to hold equipment placement and selection of antennas to be used with access points. Keep in mind that the effective distance has a value, which will decrease the radius of action after the passage of the relevant obstacles compared to open space, and the fact that the signal decreases proportional to the square of the distance, so speed comes naturally as the distance from the access point. D-Link Wi-Fi Planner Pro showed that the audience need to install 1 (2.4 GHz) access point and 3 (in the 5 GHz band) to provide a coating with a signal level not worse than -65 dBm (for providing students with only Internet access).
