1.0) What Is the Meaning of WLAN?
Wireless Local Area Networks or WLAN have been rapidly growing and getting a lot of interest from numerous people whether it was noticed or not. Basically, WLAN has been initiated by a cellular spectrum technology that being evolve to become friendly network connections. It helps us to minimize the physical wiring in designing the networks and indirectly reduce the cost of development. In spite of that, there were always been a pros and contras in terms of various criteria such as performance, data rates, and so forth need to be elaborate so we will get this things clearer. Therefore, the brief of architecture and along with its challenges faced by utilizing WLAN will be discussed in the next paragraph.
1.1) When It Was Started?
Officially, IEEE has created a standard approach for wireless technology for the usage of enterprise, home and public on 1997. However, there was some claim said that the research and study of this wireless LAN has been started earlier.
Kevin J. Negus and Al Petrick in “History of Wireless Local Area Networks (WLANs) in the Unlicensed Bands”, George Mason University Law School Conference, Information Economy Project, Arlington, in 2008 have mentioned in that article the first product of WLAN was the Telesystems “ARLAN-SST” (circa 1988) in 1988. 
1.2) How the Term Wi-Fi Get In Place?
There was no solid evidence the term “wifi” is owned by any organization. The only close to truth owner of the term “wifi” was from the WECA that chosen “WI-FI” on 802.11b Direct Sequence in 1999 and patented it as “WI-FI”  that including the computer hardware, namely, wireless local area networking products in class A However, Cory Doctorow  in his blog boingboing.net has stated that Phil Belanger, a founding member of the Wi-Fi Alliance who presided over the selection of the name “Wi-Fi” writes:
“Wi-Fi doesn’t stand for anything. It is not an acronym. There is no meaning.
Wi-Fi and the ying yang style logo were invented by Interbrand. We (the founding members of the Wireless Ethernet Compatibility Alliance, now called the Wi-Fi Alliance) hired Interbrand to come up with the name and logo that we could use for our interoperability seal and marketing efforts. We needed something that was a little catchier than “IEEE 802.11b Direct Sequence”.
