無線寬頻服務 - 2008：WiFi

Wi-Fi technology is advancing beyond the usage model of providing indoor, short-range wireless Internet access for mobile computers. The extended range of Wi-Fi access points for indoor and outdoor applications has the capability of coverage across entire campuses, thus eliminating wiring infrastructures for other types of electronic equipment. Applications and demand for new services will drive Wi-Fi to bring voice, data and video into the space of various offerings. Wi-Fi is evolving from a WLAN (Wireless Local Area Network) application to a broadband wireless service with a great deal of opportunities on a global scale.

How will WiFi hold up against WiMAX? What vendors are aggressively pursuing WiFi? What is going to happen to municipal wireless?

This report evaluates the current state of the WiFi value chain, vendors, service providers, and solutions as well as the future prospects of WiFi.
