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: One embodiment can provide a method and a system for performing multiple radio frequency allocation. During operation, the system including a controller can receive, a Wi-Fi channel allocation and a filter bank configuration associated with a Wi-Fi radio transceiver. The system can determine one or more Internet of things (IoT) radio transceivers operating with the Wi-Fi radio transceiver. For a respective IoT radio transceiver, the system can perform the following operations: determining a set of scores based on a set of constraints associated with an application type for the IoT radio transceiver; and computing a weighted average score based on the set of scores; and determining a channel allocation for the IoT radio transceiver based on the weighted average score and the Wi-Fi channel allocation.

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.

Abstract: Systems and methods are provided for optimizing the scheduling of Orthogonal Frequency-Division Multiple Access (OFDMA) transmissions in the downlink (DL) direction. A two-stage mechanism can be implemented when effectuating DL OFDMA transmission involving multiple modulation and coding schemes (MCS) in a single transmit burst. A first stage of the two-stage mechanism may use radio frequency (RF) boosting/de-boosting of Resource Units (RUs) such that the average input power to an AP power amplifier (PA) may remain under a saturated PA output power to ensure PA linearity. If RF boosting/de-boosting is not supported, an alternative mechanism for OFDMA grouping (to rigid grouping) can be employed to skip higher MCS.

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.
