    Abstract: A host controller for a distributed wireless local area network (WLAN) includes: a communications interface connected to each of a set of wireless access points (APs); a memory storing (i) identifiers of each of the wireless access points, and (ii) a master identifier of the host controller; and a processor configured to: receive a notification, from a first one of the APs, that the first AP has completed an association with a client device; in response to receiving the notification: deploy association data, including an identifier of the client device, to each of the APs; initiate a handshake mechanism with the client device, via a selected one of the APs, to generate an encryption key; and provide the encryption key to each or the APs to enable data exchange between the client device and each of the APs.

    Abstract: A calibration signal is transmitted from a transmitter antenna. A receiver antenna receives a loopback signal that results from an air coupling of the receiver antenna and the transmitter antenna. The loopback signal is compared to a target. If the loopback signal does not meet the target, then a gain of the calibration signal is adjusted and the loopback signal is again checked against the target. When the loopback signal meets the target, the gain is taken as a calibrated transmitter gain.

    Abstract: A method and apparatus for group owner (GO) renegotiation are provided. For example, the method and apparatus may be used for GO renegotiation in a wireless personal network (WPAN), for example, a 60-gigahertz (60 GHz) peer-to-peer (P2P) wireless network. The incumbent group owner (e.g., personal base station set (PBSS) control point (PCP)) controls the operation of the group. GO renegotiation can occur, for example, when a newly arriving device (e.g., a prospective group owner) is trying to connect to the PBSS and/or, for example, with PCP rearrangement among members of an existing group. As an example, after the formation of the group, the PCP may want to relinquish the role of being the PCP. A procedure is described for deciding among clients and the PCP which device will assume the role of group owner from the existing PCP in the event the role of group owner is to be reassigned.

    Abstract: A coplanar waveguide (CPW) apparatus comprises a substrate having a first surface and an opposing second surface. The substrate comprises a metal layer proximate to the first surface. The metal layer comprises a conductive trace comprising a signal line coupled to a launcher element at a first end of the signal line, and a ground plane co-planar with the conductive trace. The ground plane defines a substantially rectangular first region surrounding the launcher element and defining a second region surrounding the signal line, the first and second regions substantially devoid of conductive material. The launcher element has a substantially rectangular shape with a width greater than a width of the signal line at the first end.

    Abstract: An antenna apparatus comprises a lower assembly and an upper assembly, which together forming a cavity to contain an RF circuit device. The upper assembly comprises a waveguide flange interface at an external surface of the upper assembly. The waveguide flange interface comprises a waveguide channel extending from the external surface to an internal surface forming a surface of the cavity. An opening of the waveguide channel at the internal surface is substantially centered about a first centerline of the upper assembly parallel with the external surface and offset from a second centerline of the upper assembly parallel with the external surface, whereby the second centerline perpendicular is to the first centerline. The upper assembly is removably attachable to the lower assembly in either of a first orientation or a second orientation, whereby the second orientation represents a 180 degree rotation of the upper assembly relative to the first orientation.
