Hotspot (Wi-Fi)
A hotspot is a physical location that offers Internet access over a wireless local area network (WLAN) through the use of a router connected to a link to an Internet service provider. Hotspots typically use Wi-Fi technology.
Hotspots may be found in coffee shops and various other public establishments in many developed urban areas throughout the world. A hotspot is differentiated from a wireless access point, which is the hardware device used to provide the wireless network service.
==History==
Public access wireless local area networks (LANs) were first proposed by Henrik Sjödin at the NetWorld+Interop conference in The Moscone Center in San Francisco in August 1993.〔(Wi-Fi Timeline )- Wifi Net News〕 Sjödin did not use the term hotspot but referred to publicly accessible wireless LANs.
The first commercial venture to attempt to create a public local area access network was a firm founded in Richardson, Texas known as PLANCOM (Public Local Area Network Communications). The founders of that venture, Mark Goode, Greg Jackson, and Brett Stewart dissolved the firm in 1998, while Goode and Jackson created MobileStar Networks. The firm was one of the first to sign such public access locations as Starbucks, American Airlines, and Hilton Hotels.〔(【引用サイトリンク】title=MobileStar Network to Supply U.S. Hilton Hotels With Wireless High-Speed Internet Access )〕 The company was sold to Deutsche Telecom in 2001, who then converted the name of the firm into "T-Mobile Hotspot." It was then that the term "hotspot" entered the popular vernacular as a reference to a location where a publicly accessible wireless LAN is available.
