Abstract: An antenna device includes a plurality of dipole antennas and a port. Each of the dipole antennas is connected to the port. The dipole antennas are arranged around the port. Each of the dipole antennas comprises two ends. The device further includes a plurality of passive elements. The ends of the dipole antennas and the passive elements are interchangeably arranged around the port such that each of the passive elements is situated between ends of two different antennas from the plurality of dipole antennas. One or more switches are configured to switch between an omnidirectional state, in which the ends of the dipole antennas are not connected to the plurality of passive elements, and a directional state, in which at least one end of one of the passive elements is connected to at least one end of one of the antennas.

Abstract: A device on a wireless network generates duration data for determining a duration of a time interval. A transmission is then instructed, by the device, to transmit the duration data and a downlink payload including an aggregated Media Access Control (MAC) layer data unit, the downlink payload being transmitted on first subcarriers. The transmission also includes a trigger that configures the at least one other device on the network to transmit an uplink payload within the time interval, and during at least part of the transmission of the downlink payload, on second subcarriers that are at different frequencies to the first subcarriers.
