Dynamic channel assignment for 6 GHz radios may be provided. Whether an access point in a network is classified as low power indoor only (LPI only), standard power optional (SP optional), or standard power mandatory (SP mandatory) is determined. The total number of access points in the network and the number of access points classified as SP optional or SP mandatory is determined. If the number of SP optional and SP mandatory access points is more than a determined proportion of the total number of access points, for SP optional and SP mandatory access points, channels having a frequency below a determined power spectral frequency are cut off.

Adaptive channel assignment for 6GHZ radios

Dynamic spectrum access mode based on station capabilities is provided by categorizing functionalities of Access Points (APs) and stations (STA) in a wireless network; identifying interference induced by external signaling devices on channels in the wireless network; calculating an impact factor of the interference based on proximity of the external signaling devices to the wireless network, a pattern of the external signaling devices, and an extent of overlap with frequencies used by the external signaling devices and the wireless network; and in response to identifying a given STA that is paired with a given AP in the wireless network, wherein the given STA and the given AP are both categorized as being capable of both multilink communications and preamble puncturing, assigning network resources for the given STA to communicate with the given AP via one of multilink communications or preamble puncturing based on the impact factor of the interference.

In one embodiment, a device may obtain sensor measurements from an environmental sensor of an access point. The device may obtain traffic telemetry data regarding network traffic handled by the access point. The device may generate, based on the sensor measurements and the traffic telemetry data, a sampling configuration of the environmental sensor of the access point. The device may cause the access point to collect additional sensor measurements from its environmental sensor according to the sampling configuration.

Embodiments herein describe techniques for performing dynamic channel assignment for MLD stations using MLD distributions associated with access points (APs). The embodiments herein include techniques for considering inter-frequency isolation (also referred to as inter-spectrum isolation) as well as intra-frequency contention when assigning channels to MLDs.

This disclosure describes techniques and mechanisms for determine a change window of least impact based on the type of activity, urgency, and preference, and highlighting risk(s) of choosing a change window. The techniques streamline and automate change window technology and provide customized and personalized change window option(s) to an administrator of a network.

A network of access points may be provided. Access points operating in a low power indoor (LPI) mode and access points operating in a standard power (SP or SPI) mode are identified. The access points operating in an SP or SPI mode are sorted by available frequencies and maximum power budget. For each access point in the network, a composite radio frequency (RF) density score is determined, wherein higher density scores correspond to a denser population of access points in the network. If the composite RF density score is above a determined level, the access point that supports frequencies below a threshold level and that have an effective isotropic radiated power (EiRP) above a determined level are determined as a seed candidate. At least one of the seed candidates is determined as a seed access point.

Closed loop transmit power control

Optimal determination of wireless network pathway configurations may be provided. A computing device may detect, at a first network Access Point (AP), inference on a channel with a second AP. Then, the computing device can check availability of a redundant radio at the second AP. Based on the availability, the computing device can establish a new radio link with the redundant radio at the second AP and reroute data traffic over the new radio link to the second AP. After establishing the new radio link, the computing device can then sever the channel with the second AP.

Dynamic radio configuration for seamless backhaul frequency optimization

Access Point ranging and placement on a floorplan may be provided. A host AP may range each neighbor AP of the host AP. One or more neighbor APs that failed ranging with the host AP may be categorized in a failed neighbor AP list. The host AP may re-range each of the one or more neighbor APs in the failed neighbor AP list with a modified ranging parameter. At least one neighbor AP of the one or more neighbor APs may be categorized in the failed neighbor AP list that succeeded in re-ranging with the host AP in an extended range neighbor AP list.

The present technology allows coordination of channels of private wireless networks utilizing shared licensed and unlicensed spectrum. Wireless network operators in an enterprise location register to participate in a consortium and register licensed, shared, and unlicensed spectrum resources to be shared with other members of the consortium. The wireless network operators request an allocation of spectrum resources from the consortium. The consortium generates a radio resource management ('RRM') plan for shared use of the licensed, shared, and unlicensed spectrum resources. The consortium combines the allocated licensed, shared, and unlicensed spectrum from each of the wireless network operators to meet the target RRM plan. The consortium monitors spectrum utilization to dynamically update the RRM. The consortium monitors spectrum utilization in real time to determine how closely the RRM plan matches the resources allocated to each wireless network operator.

Dynamic configuration of Overlapping Basic Set Service Preamble Detect (OBSS/PD) parameters for an Access Point (AP) may be provided. First, a plurality of stations within a Spatial Reuse (SR) range of the AP may be determined. Next, Signal to Interference plus Noise Ratio (SINR) calculations associated with the plurality of stations may be performed to determine an SINR impact on the plurality of stations if the AP performs an SR transmission given OBSS/PD parameters currently configured for the AP. Then, based on the SINR calculations, the OBSS/PD parameters for the AP may be dynamically adjusted.

An access point in a wireless network communicates wirelessly with one or more client devices over a channel that includes a plurality of subchannels. Radar is detected on a first subchannel of the plurality of subchannels. It is determined to puncture the first subchannel, based on the detecting the radar on the first subchannel and based on one or more puncturing factors. The first subchannel is punctured, the puncturing comprising muting one or more subcarriers on the first subchannel.

Dynamic frequency coordination in shared wireless communication environments

An algorithm for determining redundant radios in APs is disclosed. The algorithm first performs a coverage peak flattening algorithm to predict an impact to the total coverage area if a radio in a selected AP does not transmit signals in a frequency band. If the impact to the total coverage area is acceptable, the algorithm then performs a multi-point check algorithm to determine whether the radio in the selected AP is redundant in the frequency band. After determining that the radio in the selected AP is redundant in the frequency band, the algorithm transforms the redundant radio into various services based on the network deployment and user preference.
