A Hotspot is a venue that offers WiFi access. The public can use a laptop, WiFi phone, or other suitable WiFi ready device to access the Internet. Hotspots are often found at restaurants, train stations, airports, libraries, hotels, hospitals, coffee shops, bookstores, department stores, supermarkets and other public places. Many universities and schools have wireless networks in their campus.

History

Wi-Fi hotspots were first proposed by Brett Stewart at the NetWorld+Interop conference in The Moscone Center in San Francisco in August 1993. Stewart did not use the term 'hotspot' but referred to public accessible wireless LANs. Stewart went on to found the companies PLANCOM in 1994 (for Public LAN Communications). There are two kinds of HotSpots: paid and free. Both paid and free hotspots continue to grow. Wireless networks that cover entire cities, such as municipal broadband have mushroomed. MuniWireless reports that over 300 metropolitan projects have been started.

Commercial WiFi hotspots

A commercial hotspot may feature:

• A captive portal that users are redirected to for authentication and payment
• A payment option using credit card, PayPal, ClickandBuy, or other payment service
• A walled garden feature that allows free access to certain sites

Major airports and business hotels are more likely to charge for service.

Hotspots Wi-Fi livres

Hotspots livres funcionam de duas maneiras::

• Utilizando uma rede pública é a forma mais fácil de criar um HotSpot livre. Tudo o que é necessário é um router WiFi. No entanto, a desvantagem é que o acesso ao router não pode ser controlado.
• As redes públicas fechadas usam um sistema de gestão do HotSpot para controlar o HotSpot. Este software funciona no próprio router ou usa um computador externo. Com a ajuda deste software, os operadores podem autorizar somente utilizadores específicos para poderem aceder à Internet, muitas vezes, associam o acesso livre a um menu ou a um limite da compra.
