Publication number: 20140133385Abstract: An apparatus for Internet-Protocol based communications in a wireless network includes a network interface, a controller, and memory. The interface receives a series of multicast data packets. The controller identifies one or more receiving nodes in the wireless network requesting data corresponding to the series of multicast data packets and determines that the effective unicast rate for one or more unicast data packets exceeds a minimum data rate of the series of multicast data packets using an 802.x protocol. The memory stores instructions that may be executable by a processor. Upon execution of the instructions by a processor, the received series of multicast data packets is converted into one or more unicast packets, the execution and conversion occurring in response to instructions received from the controller. A system for Internet-Protocol based communications in a wireless network implements such an apparatus in the context of an access point.Type: ApplicationFiled: January 21, 2014Publication date: May 15, 2014Applicant: Ruckus Wireless, Inc.Inventor: William S.

Patent number: 8723741Abstract: A device for a wireless RF link to a remote receiving device can radiate at different radiation patterns in response to detecting a change in the device position. As the device is moved, displaced, or re-positioned, a position sensor in the device detects the change in position and provides position information to a processor. The processor receives the position information from the position sensor, selects an antenna configuration and physical data rate based on the position information, and provides an RF signal associated with the selected antenna configuration through the antenna elements of the selected antenna configuration.Type: GrantFiled: May 31, 2012Date of Patent: May 13, 2014Assignee: Ruckus Wireless, Inc.Inventors: Victor Shtrom, Bernard Baron, William S.

Publication number: 20140071879Abstract: An access point of a communications network receives a multicast or broadcast packet from a source. The access point converts the multicast or broadcast packet into a unicast packet addressed to a station associated with the access point. The access point then transmits the unicast packet over the communications network from the access point to the station. The access point further may determine a minimum data rate by which the access point may transmit the multicast or broadcast packet to the station and determines an effective unicast rate for transmitting the unicast packet to the station. If the effective unicast rate does not exceed the minimum data rate, the access point does not transmit the unicast packet to the station and transmits the multicast or broadcast packet.Type: ApplicationFiled: November 14, 2013Publication date: March 13, 2014Applicant: Ruckus Wireless, Inc.Inventors: William S. Kish, John Chanak, Charles Andrew Gram

Patent number: 8670725Abstract: A system and method for improving radio performance through automatic channel selection utilizing a closed-channel model is disclosed. A measurement engine records maximum user throughput on a per station basis during normal traffic operation. The measurement engine further records throughput metrics based on test traffic sent to all associated stations during idle operation. A policy logic engine utilizes the measurements to determine an optimal transmission channel for transmission and receipt of data.Type: GrantFiled: August 20, 2007Date of Patent: March 11, 2014Assignee: Ruckus Wireless, Inc.Inventor: William S.

Publication number: 20140016563Abstract: A channel aware scheduler (CAS) is disclosed that takes advantage of changing wireless channel conditions in order to maximize aggregated system throughput. The CAS is aware of the different channel conditions for one or more stations and adjusts its scheduling of packet transmissions in light of the same. A related CAS algorithm may take advantage of that knowledge in order to increase aggregated system throughput while concurrently addressing other potential fairness constraints.Type: ApplicationFiled: September 16, 2013Publication date: January 16, 2014Applicant: Ruckus Wireless, Inc.Inventor: William S.

Publication number: 20130241789Abstract: A circuit board for wireless communications includes communication circuitry for modulating and/or demodulating a radio frequency (RF) signal and an antenna apparatus for transmitting and receiving the RF signal, the antenna apparatus having selectable antenna elements located near one or more peripheries of the circuit board. A first antenna element produces a first directional radiation pattern; a second antenna element produces a second directional radiation pattern offset from the first radiation pattern. The antenna elements may include one or more reflectors configured to provide gain and broaden the frequency response of the antenna element. A switching network couples one or more of the selectable elements to the communication circuitry and provides impedance matching regardless of which or how many of the antenna elements are selected.Type: ApplicationFiled: April 15, 2013Publication date: September 19, 2013Inventors: Victor Shtrom, Darin T.

Publication number: 20130194969Abstract: Determining associations in wireless mesh networks are provided. In a mesh network that includes a wired border node and multiple wireless nodes, each wireless node advertises a backhaul throughput approximating the throughput between that wireless node and the wired border node. Using the advertised backhaul throughput information and the stored local throughput information, a receiving node determines a node association from among various candidate nodes.Type: ApplicationFiled: January 7, 2013Publication date: August 1, 2013Inventor: William S.

Publication number: 20130181882Abstract: A horizontally polarized antenna array allows for the efficient distribution of RF energy into a communications environment through selectable antenna elements and redirectors that create a particular radiation pattern such as a substantially omnidirectional radiation pattern. In conjunction with a vertically polarized array, a particular high-gain wireless environment may be created such that one environment does not interfere with other nearby wireless environments and avoids interference created by those other environments. Lower gain patterns may also be created by using particular configurations of a horizontal and/or vertical antenna array. In a preferred embodiment, the antenna systems disclosed herein are utilized in a multiple-input, multiple-output (MIMO) wireless environment.Type: ApplicationFiled: November 20, 2012Publication date: July 18, 2013Inventors: Victor Shtrom, William S.

Publication number: 20130010775Abstract: Systems and methods for improving data transmission rates in communication networks are disclosed. In an 802.11 wireless communication network, where a source node of the wireless network transmits TCP data to a destination node of the wireless network, the destination node does not transmit TCP acknowledgments (ACKs) for the TCP data if 802.11 ACKs indicate that the destination node received the TCP data. If a source outside the wireless network transmits TCP data to the destination node within the wireless network through an intermediate device, such as an access point, the destination node suppresses transmitting TCP ACKs. The intermediate device transmits TCP ACKs as proxy for the destination node to the source. The intermediate device also suppresses TCP ACKs where a source node within the wireless network sends the TCP data to a destination node outside of the wireless network.Type: ApplicationFiled: July 13, 2012Publication date: January 10, 2013Inventors: William S.

Patent number: 8150470Abstract: A system and method for improved data transmission on a wireless link to a remote receiving node includes a communication device for converting packets to RF at a physical data rate, an antenna apparatus having a plurality of antenna configurations for transmitting the RF, and a processor for selecting the antenna configuration and the physical data rate based on whether the remote receiving node indicated reception of the data transmission. The processor may determine a table of success ratios for each antenna configuration and may rank each antenna configuration by the success ratio. The processor may transmit with an unused antenna configuration to probe the unused antenna configuration and update the table of success ratios. Similarly, the processor may maintain a table of effective user data rates, rank each physical data rate by the effective user data rate and probe unused physical data rates to update the table.Type: GrantFiled: February 28, 2011Date of Patent: April 3, 2012Assignee: Ruckus Wireless, Inc.Inventors: William S.
