Patent number: 9313798Abstract: Initiating a virtual presence at a physical access point in response to a request for a service from a wireless access device is provided. A particular wireless service may be provided to a subscriber on an on-demand basis according to location and/or type of service requested. The service may be terminated when demand for the service comes to an end whereby a common wireless service infrastructure may be shared amongst service providers thus eliminating the need for radio channel coordination and otherwise enhancing service quality for those service providers.Type: GrantFiled: December 30, 2014Date of Patent: April 12, 2016Assignee: Ruckus Wireless, Inc.Inventors: Ted Tsei Kuo, Ming-Jye Sheu, Tian-Yuan Lin, Tyan-Shu Jou

Patent number: 9131378Abstract: Systems and methods for authentication using paired dynamic secrets in secured wireless networks are provided. Each authenticated user is assigned a random secret generated so as to be unique to the user. The secret is associated with a wireless interface belonging to the user, so that no other wireless interface may use the same secret to access the network. The secret may be updated either periodically or at the request of a network administrator, and reauthentication of the wireless network may be required.Type: GrantFiled: November 13, 2013Date of Patent: September 8, 2015Assignee: Ruckus Wireless, Inc.Inventors: Tyan-Shu Jou, Ming-Jye Sheu, Bo-Chieh Yang, Tian-Yuan Lin, Ted Tsei Kuo
