wireless LAN

(wireless Local Area Network) A communications network that provides connectivity to wireless devices within a limited geographic area. Wi-Fi is the universal standard for connecting laptops and mobile devices in a home or office. It is commonly deployed alongside of Ethernet, and both wireless and wired devices can exchange data with each other for backup and file sharing. At home, Wi-Fi can also serve as the only network since all laptops and many printers come with Wi-Fi built in, and Wi-Fi can be added to desktop computers via USB. See Ethernet.

Wi-Fi is achieved with a wireless base station, called an "access point" (AP). The access point's antennas transmit and receive radio frequencies within a range of 30 to 150 feet indoors through walls and other non-metal barriers. The outdoor range can be double that or more. For Wi-Fi standards, see 802.11. See Wi-Fi hotspot, cellular hotspot, wireless router, LAN switch, wireless broadband and WPAN.

Wi-Fi in a Company
In a big company, access points, switches and routers are stand-alone devices. In addition, industrial strength commercial products can cost 10 times as much as consumer devices.

Wi-Fi in the Home
For the home and small office, a wireless router combines three network devices in one box. For more details, see wireless router.

Call it what you will, the market for WLAN security devices, whether appliances or switches, has developed both fast and--perhaps because of its current lack of unity--largely out of view for the majority of technology market analysts.
Technavio's analysts forecast the global WLAN security market to grow at a CAGR of 19.93% during the period 2016-2020.
The rest of this paper is organized as follows: Section II discusses salient features of Integrated UMTS and WLAN network, section III introduces vertical handoff strategy, section IV introduces scenario configuration and section V introduces simulation results and analysis.
WiNG Express requires virtually no IT department support with an easy-to-use, easy-to-understand graphical user interface that simplifies end-to-end WLAN management.
In the study in [10], the number and locations of the APs are determined in the indoor WLAN installations so that WLAN costs (cable length, number of switches etc.) are minimized.
From its corresponding S11 results presented in Figure 2(b), the proposed antenna has impedance bandwidth for [S.sub.11] [less than or equal to] -10 dB of 170 MHz (2.38-2.55 GHz) resonated at 2.48 GHz, 720 MHz (3.34-4.06 GHz) resonated at 3.66 GHz, and 1460 MHz (5.07-6.53 GHz) resonated at 5.64 GHz, which can both well cover the 2.4/5.2/5.8 GHz WLAN bands and 3.5/5.5 GHz WiMAX bands.
Through this relationship, ScanSource resellers are able to assist their end-user customers with the management of their WLAN networks from a hosted controller.
For [S.sub.11] <--10dB, the measured impedance bandwidths are about 120 MHz (2.38-2.5 GHz), 320 MHz (3.35-3.67 GHz) and 1750 MHz (4.76-6.55 GHz), covering WLAN and WiMAX bands.
