2014

In Gartner 2014 June's Magic Quadrant for Wired and Wireless LAN Infrastructure report, for the 3rd year in a row, Cisco, Aruba and HP Networking are positioning at Leaders quadrant, which are same as last two years. On May 19, 2015, HP completed the acquisition of Aruba Networks for a transaction value of $3 billion. In Gartner's 2015's report, there will be only two vendors showing in the Leaders quadrant.

Huawei, Dell and D-link lost their challengers position and become niche players. Aerohive, Acatel-Lucent Enterprise, Ximus and Avaya are in visionaries quadrant, which means they have innovated in one or more of the key areas of access layer technologies within the enterprise (e.g., convergence, security, management or operational efficiency).
