Hot Spots - Eric Howard

A hotspot is a site that offers Internet access over a wireless local area network through the use of a router connected to a link to an Internet service provider. Hotspots typically use Wi-Fi technology for the wireless network. Hotspots may be found in coffee shops and various other public establishments throughout much of North America and Europe. The public can use a laptop, Wi-Fi phone, or other suitable portable device to access the wireless connection (usually Wi-Fi) provided. Of the estimated 150 million laptops, 14 million PDAs, and other emerging Wi-Fi devices sold per year for the last few years, most include the Wi-Fi feature.

For venues that have broadband Internet access, offering wireless access is as simple as purchasing one AP, in conjunction with a router and connecting the AP to the Internet connection. A single wireless router combining these functions may suffice.

Free hotspots operate in two ways, uing an open public network is the easiest way to create a free HotSpot. All that is needed is a Wi-Fi router, private users of wireless routers can turn off their authentication requirements, thus opening their connection, intentionally or not, for sharing by anyone in range. The disadvantage is that access to the router cannot be controlled. Closed public networks use a HotSpot Management System to control the HotSpot. This software runs on the router itself or an external computer. With this software, operators can authorize only specific users to access the Internet, and they often associate the free access to a menu or to a purchase limit. Operators are also now able to limit each user's available bandwidth - each user is therefore restricted to a certain speed to ensure that everyone gets a good quality service. Often this is done through Service Level Agreements.
