Abstract: Systems and techniques are described that are directed to filter frequency response shift compensation, including compensating for shifting in the rejection band of the filter. Compensation for the shifting in the rejection band can include applying a pre-distortion to attenuate edge resource units (RUs), and applying PHY Protocol Data Unit (PPDU) scheduling schemes. For example, a PPDU scheduling scheme reduce bandwidth in the channel, thereby dropping the out of band RUs. Front ends provide feedback to a respective radio, which allows that radio to apply the appropriate pre-distortion. The front ends can include one or more filters enabling frequency domain coexistence between collocated radios operating in the differing Wi-Fi bands, and a coupler that provides the feedback indicating the frequency response shift to a radio. The radio can then apply a digital pre-distortion to compensate for the shifting in the rejection band.

Abstract: Dynamic configuration of multiple radios of an access point is described. An example of an access point includes a processor; a memory; hardware filters; and a first set of radio chains and antennas, the access point including a first radio mode for operation as a single radio on a first channel to service a first BSS and a second radio mode for operation as a first radio on the first channel and a second radio on a second channel to perform an additional service, wherein the access point is to provide dynamic configuration of the radios including, upon determining that operation of the first channel to service the first BSS is not compatible with a particular hardware filter of the first radio, migrating the first BSS from the first radio to the second radio to service on the second channel, and providing the additional service on the first channel.

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: 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 one of a 5 GHz band and a 6 GHz band, and generating, by the network device, a second signal in the other one of the 5 GHz and 6 GHz bands. Examples may include selecting, by the network device, a first filter or a second filter to be applied to the one of the first and second signals in the 5 GHz band, wherein the second filter allows a higher frequency band to pass than the first filter in the 5 GHz band and the second filter is narrower than the first filter, selecting, by the network device, a third filter or a fourth filter to be applied to the other one of the first and second signals 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 the third filter is narrower than the fourth filter, and 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: Disclosed herein, one embodiment of the disclosure is directed to a system, apparatus, and method for enabling simultaneous transmit and receive in the same Wi-Fi band within a device by first obtaining a first information corresponding to a first set of signals to be transmitted wirelessly by a first antenna of a first device and transmitting, by the first antenna of the first device, the first set of signals. Then, a second set of signals comprising: (a) the first set of signals transmitted by the first antenna of the first device and (b) a third set of signals transmitted by a second device different than the first device are received by a second antenna of the first device. Thereafter, a second information representing the second set of signals received by the second antenna of the first device is obtained. Last, based on the first information and the second information, a third information comprising an estimation of the third set of signals without the first set of signals is determined.

Abstract: An example cooling system for a wireless networking device is presented. The cooling system includes a Peltier cooler disposed in thermal contact with a radio-frequency (RF) filter coupled to a transceiver disposed in the wireless networking device. Further, the cooling system includes a thermal management controller coupled to the Peltier cooler and the transceiver. The thermal management controller is configured to receive a signal indicating whether the transceiver is performing a data communication. In response to determining that the transceiver is performing the data communication, the thermal management controller operates the Peltier cooler to actively cool the RF filter. However, in response to determining that the transceiver is not performing the data communication while the wireless networking device is powered on, the thermal management controller operates the Peltier cooler to stop actively cooling the RF filter.

Abstract: Systems and methods are provided by which all APs in a particular deployment can be used to assist in the out-of-band discovery of 6 GHz radios by client devices. That is, a series of iterative operations can be performed to: (I) determine the state of 6 GHz radios in a zone/deployment area; (II) identify what radios can be considered near-neighbors to non-6 GHz radios for purposes of advertising one or more of the 6 GHz radios; (Ill) rank neighboring 6 GHz radios for a given non-6 GHz radio based on certain radio metrics; and (IV) ultimately determine those 6 GHz radios that can be advertised by the given non-6 GHz radio.
