Abstract: Implementations of the present disclosure relate to resource unit (RU) assignment to combat frequency selective fading. A method comprises determining, at an access point (AP), a plurality of channel qualities of a plurality of resource units (RUs) for a client. The plurality of RUs are configured to be available for communications with a plurality of clients comprising the client. The method further comprises determining, from the plurality of RUs, a target RU for the client based at least in part on the plurality of channel qualities. The target RU is to be used by the client for a following transmission with the AP. A target RU with good channel quality will be assigned to the client, thus the transmission and overall system performance will be enhanced.

Abstract: A system and method for configuring a plurality of access points (APs) providing service coverage to a space is described. The system determines a number of users in the space. Responsive to the number of users exceeding a predetermined threshold, the system can place the plurality of APs in a high-power mode and cause an antenna of each AP to operate in a narrow-beam mode. Responsive to the number of users being below the threshold, the system selects a subset of APs from the plurality of APs and causes an antenna of each AP in the subset to operate in a wide-beam mode. Each AP in the subset remains in the high-power mode, and the wide-beam mode has a wider radiation pattern in a horizontal plane than the narrow-beam mode. The system places the remaining APs in a power-saving mode, thereby reducing energy consumption while maintaining service coverage.

Abstract: In implementations of the present disclosure, a power compensation determination for radio frequency cable mechanism is provided. An access point (AP) determines a time slot for an RF cable loss measurement on an RF cable, and transmits a test signal with a first TX power to an antenna module over the RF cable. The AP further obtains a second TX power transmitted by the antenna module, and determines an RF cable loss based on the first TX power and the second TX power. The AP further determines power compensation for the RF cable based on the determined RF cable loss, the first TX power and an antenna gain of the antenna module. The AP transmits signals on the RF cable to the antenna module based on the determined power compensation. Implementations of the present disclosure can determine the power compensation based on the RF cable loss automatically.

Abstract: Examples described herein provide selective filtering by a network device for continuous 5 GHz and 6 GHz operation. Examples may include receiving, by the network device, a first signal in a 5 GHz band, and generating, by the network device, a second signal in a 6 GHz band. Examples may include selecting, by the network device, a first filter or a second filter to be applied the first signal in the 5 GHz band, wherein the first filter allows a lower frequency band to pass than the second filter in the 5 GHz band, selecting, by the network device, a third filter or a fourth filter to be applied to the second signal in the 6 GHz band, wherein the third filter allows a lower frequency band to pass than the fourth filter in the 6 GHz band, and simultaneously applying, by the network device, the selected first or second filter to the first signal and the selected third or fourth filter to the second signal.

Abstract: An antenna device may include an antenna element, a planar grounding element, a first connecting element, and a second connecting element. The antenna element includes a radiator arm, a shorting arm, and a feeder arm, the shorting arm and the feeder arm being coplanar to and extending from a first edge of the radiator arm, the feeder arm extending parallel to the shorting arm. The first connecting element connects the shorting arm of the antenna element to the planar grounding element to position the antenna element and the planar grounding element in separate parallel planes. The second connecting element extends from and perpendicular to the feeder arm of the antenna element.

Abstract: A power-over-Ethernet (PoE) powered device (PD) comprises a PoE interface to receive a connector of an ethernet cable to connect the PD to a PoE power sourcing equipment (PSE). The PD comprises a first power line connected to the PoE interface to receive PoE power from the PSE in a connected state of the PD to the PSE. The PD also comprises a rectifier comprising a first input connected to the first power line, a first output connected to a first terminal of a PD chip, and a first rectifying element connected between the first input and first output. The PD further comprises a first capacitor connected in parallel to the first rectifying element between the first input and the first output. AC noise appearing on the first power line is bypassed around the first rectifying element via the first capacitor.

Abstract: An example method for selectively filtering Wi-Fi signals is presented. A first radio and a second radio of a wireless networking device (WND) are respectively operated on a first channel and a second channel. The first channel and the second channel are respectively within a first sub-band of a first frequency band and second sub-band of a second frequency band. A control unit of the WND may select one of a first filter or a second filter based on the first channel, and one of a third filter or a fourth filter based on the second channel. After the filters are selected, signals over the first channel are communicated through a selected one of the first filter or the second filter, and signals over the second channel are communicated through a selected one of the third filter or the fourth filter.
