Adjusting a Modulation and Coding Scheme (MCS) or more generally, Layer One parameters, for a data packet based on packet information and priority is disclosed. The packet information can typically be extracted from the packets header. Considering packet-specific information enables cross-layer optimization that can include consideration of packet error rate (PER) constraints, delay constraints, relative importance of packets within a data stream, beamforming (e.g., off or on, implicit or explicitlonger distances are more likely to merit implicit beamforming) constraints, and aggregation as a function of MCS or channel condition (more aggregation is generally desirable for higher MCS or better channels), to name several examples. It is also possible to differentiate drop probability based on the importance of frames like anchor frames, etc.

Interference cognitive devices are described. An interference cognitive device can be collocated with a transmitter of an interference cognitive transmitter (ICT), as receive chains or portions thereof at the ICT. An interference cognitive device can also be remote with respect to the transmitter, which operates in an interference cognitive network and receives data directly or indirectly from the interference cognitive device. The ICT uses the data to mitigate interference while continuing to operate in accordance with a performance metric.

A technique for expanding the range of coverage for a wireless local area network (WLAN) involves locating a wireless access point (WAP) away from an interworking unit (IWU) at the edges of the WLAN and a (typically) wired network. The WAP, when located away from the IWU, can be referred to as an untethered access point (UAP) because it communicates with the IWU on a wireless channel. Stations on the WLAN will be capable of communicating with the WAP, whether or not it is a UAP, via a known or convenient wireless protocol, such as Wi-Fi, and may or may not be capable of communicating with one another via a direct station-to-station protocol.


Patent
Quantenna Communications | Date: 2014-03-28

A wireless access point (WAP) including: a station set identifier and a subnet controller. The station set identifier is configured to identify at least one set of at least two station nodes among the plurality of station nodes and complementary communication options for each station in the at least one set which facilitate concurrent communications between the WAP and the stations in the set. The subnet controller is configured both to generate subnets equal in number to a number of stations in at least one set, and for each subnet an associated beacon channel discrete from the beacon channels of other subnets, together with any required aggregate channels matching each stations identified communication option and an associated medium access control, and further to control transmission of data from the WAP to the at least two station nodes concurrently on the associated subnets.

Interference cognitive devices are described. An interference cognitive device can be collocated with a transmitter of an interference cognitive transmitter (ICT), as receive chains or portions thereof at the ICT. An interference cognitive device can also be remote with respect to the transmitter, which operates in an interference cognitive network and receives data directly or indirectly from the interference cognitive device. The ICT uses the data to mitigate interference while continuing to operate in accordance with a performance metric.

Quantenna Communications | Date: 2011-08-24

A technique for utilizing an intermediate access point (IAP) with a wireless access point (WAP) that uses 3-address mode involves making use of a bridge table that includes media access control (MAC) addresses of stations registered with the IAP and internet protocol (IP) addresses of the stations stored in association with the corresponding MAC address. A bridging engine can obtain an IP address from a WAP IP frame and match the IP address to an IP address in the bridge table to find the corresponding MAC address. The bridging engine can encapsulate at least a portion of the WAP IP frame to create an IAP frame with the corresponding MAC address as the receiver address (RA).

A diagnostic system for spatial diagnosis of the WLAN includes: a sounding aggregator and a spatial correlator. The sounding aggregator is configured to aggregate multiple-input multiple-output (MIMO) channel state information (CSI) from channel soundings of the WLAN, including channel soundings between a wireless access point (WAP) node and associated station nodes on a selected one of a plurality of communication channels of the WLAN. The spatial correlator is coupled to the sounding aggregator and configured to correlate CSI from the channel soundings with spatial characteristics of the WLAN including at least one of: a change in location of a WLAN node, human activity among the WLAN nodes, and structural impediments among WLAN nodes.


Patent
Quantenna Communications | Date: 2015-06-16

A transceiver for a wireless local area network (WLAN) and the transceiver including a sounding feedback module and a sounding feedforward module. The sounding feedback module is responsive to an explicit sounding from a transmitting one of the nodes to send feedback of multiple-input multiple-output (MIMO) channel state information (CSI) derived from the channel sounding to the transmitting one of the nodes for improving subsequent transmissions. The sounding feedforward module is configured to monitor changes in CSI since the last explicit sounding based on CSI determined from the subsequent transmissions of the transmitting one of the nodes and responsive to a determination of a change in CSI above a threshold amount, to feedforward to the transmitting one of the nodes indicia of the change in CSI.


Patent
Quantenna Communications | Date: 2010-05-11

A low complexity primary user detection system is disclosed. Signals are filtered to reduce the number of signals that must be processed. Width and PRI of the signals are used to match a constellation associated with a primary user. If the constellation is matched, communication parameters are adjusted to make way for the primary user.
