This IDC study represents the vendor assessment model called the IDC MarketScape. This research is a quantitative and qualitative assessment of the characteristics that explain a vendor's success in the marketplace and help anticipate the vendor's ascendancy. The study assesses the capability and business strategy of 12 of the top enterprise wireless LAN (WLAN) vendors. This evaluation is based on a comprehensive framework and a set of parameters expected to be most conducive to success in providing enterprise WLAN solutions, during both the short term and the long term. As the enterprise WLAN market is highly competitive and relatively mature, all vendors performed relatively well in the study.
