Wireless is a collective term used to describe different technologies that use radio transmitters and receivers to link computers.Wireless services are quickly gaining popularity across the world and, as they do, products and services are being developed and upgraded to meet demand. For example, where the adoption of broadband has been limited due to lack of broadband-enabled telephone exchanges, or businesses being too remote, broadband has been delivered by using variations of wireless technology.
WiFi:Wireless local area network hotspots, known as WiFi hotspots, are being rolled out globally. They can be subscription only, pay-per-use or free to use and they often appear in airports, hotels, cafes, pubs and motorway service stations. Some operators also offer mobile phone style "roaming" facilities.
Wimax:Wimax (Worldwide Interoperability for Microwave Access) is a fast-emerging alternative to WiFi. Wimax offers a much greater reach than the existing WiFi broadband, making it possible to provide broadband to areas where other technology is unsuitable.
