Abstract: Techniques are disclosed for generating 802.11 packets that simulate an 802.11ba Wake-Up Radio (WUR) packet by wireless access points (APs) that implement pre-802.11ba standards. According to one embodiment disclosed herein, a predefined bit stream including a plurality of data bits is evaluated. A data bit of the plurality is mapped to one of a plurality of subcarriers. A symbol is encoded in a data payload of a network packet based on the mapping of the data bit to the subcarrier. The symbol simulates an on-off key (OOK)-modulated symbol in a WUR sequence. The network packet is transmitted to a client device.

Abstract: Presented herein are techniques to ensure power emitted by APs during a cooperative MIMO transmission is within certain limits. For a transmission to be made from two or more wireless access points using cooperative multiple-input multiple-output (MIMO) techniques, a measure of separation is determined between the two or more access points. Precoding of signals to be transmitted by the two or more access points is adjusted so as to derate the signals to be transmitted or disable the cooperative nature of the transmission from the two or more access point depending on the measure of separation so that a combined output power from the two or more access points is within a limit.

Abstract: The embodiments herein use polarization diversity between antennas where the antennas for one cell are, e.g., horizontally polarized and antennas for the other cell are vertically polarized. In one embodiment, the antennas for a macro cell are vertically polarized while micro cell antennas are horizontally polarized. In one example, the micro cell antennas are printed antennas that form a loop that is co-planar with the magnetic fields generated by the macro cell antennas when transmitting. Because the magnetic fields are co-planar (rather than orthogonal) to the current flowing through the loop in the micro cell antenna, the effect of the electromagnetic signals emitted by the macro cell antenna is reduced. This may permit dual radio network devices to have improved performance when operating simultaneously—e.g., when the macro cell radio is transmitting and the micro cell radio is receiving at or near the same frequency band.

Abstract: A combination of near omni-directional antennas and internal patch antennas, all built into an access point in accordance with FCC requirements. Typically a printed antenna array is used for the near omni-directional antenna, and the internal patch antenna is a TM10 mode stacked patch antenna. A mechanical detect switch changes antenna types automatically, depending on the rotation state of the antenna system. Alternately, a configuration utility enables a user to select the antenna type for the access point when it is installed in the field. This arrangement gives the UNII access point flexibility to be mounted in various orientations and match the characteristics of the antenna to the installation requirements.

The flexible substrate preferably has a desired dielectric property to provide a desired capacitance between the antenna elements. One or both of the antenna elements are formed on the respective opposing surface. The antenna element is preferably formed by printing.
