20130094486 | Wireless Network Virtualization For Wireless Local Area Networks - An access point of a wireless network including: a controller for emulating a first virtual access point of a first service provider and a second virtual access point of second service provider; a transceiver port for communicating control signals to clients of the first and service providers to limit the uplink air-time of the clients; and a connection port for linking the first and second service providers to a backhaul. | 04-18-2013 |
20130100807 | HYBRID WIRELESS VIRTUALIZATION ARCHITECTURE - According to one embodiment of the invention, a method for optimizing revenue for an operator of a network comprises receiving control information by a network device. The control information includes a first airtime representing an amount of airtime used for wireless data transmissions to a first group of network devices. The method further involves an operation of computing an airtime allocation for the first group of network devices based on the first airtime and lease rates. The lease rates are prices per unit of airtime to be paid by an operator associated with one or more of the network devices. | 04-25-2013 |
20140269752 | APPARATUS AND METHOD AGGREGATION AT ONE OR MORE LAYERS - A method for performing aggregation at one or more layers starts with an AP placing at a first layer one or more received frames in a queue at the AP. When a transmit scheduler is ready to transmit an aggregated frame corresponding to the queue, the AP may iteratively select a plurality of frames selected from the one or more received frames, and aggregate at the first layer the plurality of frames into the aggregated frame. The number of frames included in an aggregated frame may be based on at least one of: a dynamically updated rate of transmission associated with a size of the frames, a class of the frames, a transmission opportunity value associated with the class of the frames and a total projected airtime for transmitting the aggregated frame. Other embodiments are also described. | 09-18-2014 |
20150117235 | Enhanced Dynamic Multicast Optimization - The present disclosure discloses a system and method for enhanced dynamic multicast optimization based on network condition measurement. The system includes a processor and a memory storing instructions that, when executed, cause the system to: measure a network condition for a multicast group using one or more metrics; determine whether to convert all stations in the multicast group to unicast based on the network condition; and responsive to determining not to convert the all stations in the multicast group to unicast, determine, based on the network condition, a sub set of the multicast group for converting the subset of the multicast group to unicast, wherein the subset includes less than all stations in the multicast group. | 04-30-2015 |
20150223168 | AUTOMATIC DELIVERY TRAFFIC INDICATION MESSAGE INTERVAL CONTROL FOR BETTER MOBILE POWER SAVE PERFORMANCE - The present disclosure discloses a method and network device for automatic delivery traffic indication message (DTIM) interval control for better mobile power save performance. The disclosed network device determines one or more characteristics for at least one client device connected to an Access Point (AP). The network device then dynamically selects a DTIM interval for the AP based on the characteristics for the at least one client device, and configures the AP to transmit a DTIM beacon frame at a frequency based on the dynamically selected DTIM interval. Alternatively, the network device can determine one or more characteristics for a client device, and dynamically select a Virtual Access Point (VAP) for providing network access to the client device based on the characteristics for the client device and a DTIM interval configured for the VAP, and then cause the client device to connect to the VAP. | 08-06-2015 |
20150312012 | ENFORCING STATION FAIRNESS WITH MU-MIMO DEPLOYMENTS - A non-transitory computer readable medium including instructions which, when executed by one or more hardware processors, causes performance of operations. The operations include: obtaining a first pathloss value for a first data transmitted between a first device and a second device; receiving, at a first component of the first device, a second data to be transmitted to the second device; based at least on the first pathloss value: selecting a first subset of the second data for transmission from the first component to a second component of the first device, where the second component is configured for causing transmission of the first subset of the second data to the second device; transmitting, during a first period of time from the first component to the second component, the first subset of the second data. | 10-29-2015 |
20150312861 | METHOD AND SYSTEM FOR DEVICE AWARE POWER SAVE - A non-transitory computer readable medium includes instructions. The instructions, when executed by one or more hardware processors, causes performance of operations including receiving, at an access point, data targeted for a device, and determining whether an amount of the data targeted for the device is above a threshold. The operations further include, responsive at least to determining that the amount of data is below the threshold, transmitting a notification frame falsely indicating that the access point does not have the data targeted for the device. | 10-29-2015 |
20150312875 | METHOD AND SYSTEM FOR CLIENT DEVICE LOCALIZATION - A system includes one or more hardware processors causing performance of operations. The operations include transmitting, by a first access point, a set of one or more wireless signals that include a request for feedback information. The set of wireless signals incorrectly identifies a second access point as the sender of the set of wireless signals instead of correctly identifying the first access point as the sender of the set of wireless signals. The operations further include receiving, from a client device associated with the second access point, a feedback information corresponding to the receipt of the set of wireless signals by the client device, and, based on the feedback information: determining a distance between the first access point and the client device that is associated with the second access point. | 10-29-2015 |
20150312877 | DETECTING MOVEMENT IN A PHYSICAL ENVIRONMENT - The present disclosure discloses a method and network device for detecting movement in a physical environment. Specifically, a network device obtains a first feedback information for a first set of wireless signals transmitted by a first device in a physical environment and received by a second device in the physical environment. Moreover, the network device obtains a second feedback information for a second set of wireless signals transmitted by the first device and received by the second device. The network device then compares the first feedback information to the second feedback information to identify a first set of one or more difference values. Based on the first set of one or more difference values, the network device determines that one or more physical entities within the physical environment have moved. | 10-29-2015 |
