A Wireless LAN (WLAN or W-LAN) is a “Local Area Network” for wireless users, whether in a residence, dedicated business setting or in the nature of a mobile user off-premises. The connection is made through a wireless (radio Wi-Fi) connection. A Wireless LAN’s network links two or more devices using a wireless, a multi-channel delivery method within designated, finite areas such as a café, office building, home, school or any business that makes available to its employees or guests the availability or privilege of connecting to the internet.
Security is top-of- mind, with speed the most requested priority. Wi-Fi networks are usually deployed in an infrastructure node, where a base station will act as a hub or wireless access point hub. Sometimes called a “Hotspot”. Nodes then communicate through the hub, which most usually but not in every instance, has a wired or fiber network connection There may be permanent wireless connections to other nodes and a hard-wired redundant network used as a backup instead of the original primary system. Networks may offer multiple access points, within the same security SSID system. The client software would try to choose the best signal through the strongest access point. IT Central Station users choose Wireless LANs based on criteria such as ease of system management, the best available technical features, monitoring systems, open platforms, user support/vendor updates and reasonable cost. It is essential to detect and minimize any signal strength interference and implement adequate coverage. The IT professional will assess how many Wi-Fi units are needed, where they are placed and the quality and strength of roaming so client devices seamlessly navigate. Bandwidth and scalability need to be balanced with the thought of future needs, and one must take into account the speed of evolving technology to mitigate investments.
Some are of the opinion that Wi-Fi itself is ubiquitous and mainstream, yet becoming problematic because of access security, vital equipment compatibility and bandwidth and load balancing. The software needs to be updateable and brand reputation and longevity becomes an issue when forecasting ahead 5 years+.
Wireless LANs must secure networks from non-credentialed users, yet allow authorized and guest users access. IT Central Station IT professionals are aware that the best available computers and peripheral equipment investments up front are the prudent choice to anticipate IP telephony, growth of bandwidth, video- conferencing and multi-media use that can on some levels grow exponentially. Some users will find large data files presently work better through a legacy Ethernet connection, but this may quickly change and the FCC is now a factor in available resources.
