WiFi: what's next?

WiFi, also known as 802.11b, has become the preferred technology for wireless local area networking in both business and home environments. Even though it was designed primarily for private applications, WiFi is also being deployed in public places to create so-called hotspots, where WiFi-capable users can obtain broadband Internet access. This new domain of application could be the major future market opportunity for WiFi, but in order to take advantage of it, several key challenges, both technical and business-related, must be overcome. We outline these challenges and discuss approaches to solutions.
