    Abstract: A method includes generating a data packet at a source device for transmission via an Institute of Electrical and Electronics Engineers 802.11 wireless network. The data packet includes multiple data symbols that are duplicated in the data packet. At least a portion of a preamble of the data packet is not duplicated in the data packet. The portion of the preamble indicates that the packet is a low rate mode packet. The method also includes transmitting the data packet from the source device to a destination device via the wireless network.

    Abstract: Systems, methods, and devices for communicating in a wireless network are provided. In some aspects, an access point may comprise a receiver configured to receive an access request message from a wireless station, the message comprising an indication of a plurality of network connection available to the wireless station including a link to a second access point. The receiver may be further configured to receive connectivity information associated with the link, based on the indication, from the second access point. The access point may further comprise a processor configured to determine whether to grant access to the wireless station based, at least in part, on the indication and the connectivity information, and a transmitter configured to transmit a response to the wireless station based on the determining.

    Abstract: Methods, devices, and computer program products for improving training field design in packets with increased symbol durations are disclosed. In one aspect, a method of transmitting a packet on a wireless communication network is disclosed. The method includes transmitting a preamble of the packet over one or more space-time-streams, the preamble including one or more training fields configured to be used for channel estimation, the one or more training fields each comprising one or more symbols of a first symbol duration. The method further includes transmitting a payload of the packet over the one or more space-time-streams, the payload comprising one or more symbols of a second symbol duration, the second symbol duration greater than the first symbol duration.

    Abstract: An 802.11ac access point (AP) may be capable of communicating with both 802.11n (on 40 MHz band) and 802.11ac devices (on 80 MHz band). While the 802.11ac AP is communicated with 802.11n devices on 40 MHz band, the remaining 40 MHz band is wasted because the 802.11n devices are not capable of communicating on this band. The AP may operate as if it is two virtual APs, one capable of communicating with 802.11n devices on a first primary and a first secondary channels (basic service set 1—BSS1) and the second communicating with 802.11ac devices on a second primary and a second secondary channels (BSS2). Individual beacons may be sent for BSS1 and BSS2. The transmissions on BSS2 may be performed simultaneously with transmissions on BSS1. However, transmission on one channel and receiving on the second channel cannot happen simultaneously.
