Background
Wireless Local Area Networks (WLANs), including wireless mesh networks, have one or more Access Points (APs) that communicate with various types of wireless or wired client devices in a building, either in routers, speakers, or other devices in different rooms. Thus, an AP network may be formed of multiple APs and multiple different types of client devices. Some AP networks provide handoff between APs in the same building or environment so that a client device, such as a smartphone, tablet, wearable device, or other device, can handoff from one AP to another AP in the same network to provide higher signal strength as the user moves the device throughout the environment. However, many current AP networks are inefficient with respect to the connectivity tuning that different types of wireless devices have.

Detailed Description
Methods, devices, systems, and apparatuses are described for controlling wireless devices using aggregated data from cross-network access points. An Access Point (AP) provides operational information to a cloud service from a plurality of different types of client devices in communication with the AP, and obtains per-client device type policy data from the cloud service, the per-client device type policy data based on aggregated operational information from the plurality of different types of client devices from different AP networks. Using a wireless transceiver, the AP controls wireless client devices belonging to a first type by using per-client device type policy data for the first type based on aggregated operational information of a plurality of different types of client devices from different AP networks. An Access Point (AP), such as a wired or wireless building AP, collects operational information including statistics and metrics related to the operation of each of its associated client devices and uploads the operational information to a cloud service. The cloud service uses this information to generate generalized (profile) data and policies per client device type to optimize performance of each device type using operational information from different AP networks for the same device type. The groups of different AP networks may be any desired grouping, such as but not limited to all APs in a particular geographic area, across each client type in a particular region, such as a state, or across countries, or access points in different networks that support a mesh. The act of generalizing different client types across the same device type or different device types from different AP networks allows a particular device type to be tuned and have connectivity optimized on a per client device type basis. Aggregating operational information from different AP networks allows for fast collection of significance statistics (collection statistics) for a large number of different types of wireless devices and/or for new wireless device types.

At block 302, the access point requests user approval to allow communication and monitoring of operational information. For example, AP 111 requests approval by the app on
At block 304, if the user does not approve, the process ends. However, if the user approves, the AP provides operation information of the wireless client device communicating with the AP to the cloud service at block 306. For example, AP 111 provides operational information for

In one aspect, per-client device type
As an example, processor(s) 402 generates client device
In one aspect, the data rate of a particular type of client device is compared to the data strength characteristics of the data, for example, to determine what signal strength level of a given device type provides the best data rate and the signal strength level that provides a certain data rate. For example, one smartphone type may require a lower signal strength level to provide the same data rate as another type of smartphone, as determined from data across all relevant AP networks. As such, the signal strength summary data for a particular device type includes data representing different signal strength levels and associated data rate levels experienced by different APs on different networks for the same type of device. Policy data per client device type is then generated based on the signal strength summary data, for example, by applying rule data, through policy definition by an administrator, or by applying any suitable decision algorithm. This allows, for example, to save energy and/or reduce cross-talk, especially for battery-operated APs.
In another aspect, the connection characteristics of different radio access technologies are generalized such that the number of connections tracked for a particular device type at 2.4GHz is compared to the number of connections for the same type of device operating at 5 GHz. The inductive data may indicate, for example, that a particular device type "a" only gets a correct connection to the 5GHz channel 40% of the time, while a different device type "B" has a 90% connection rate at 5 GHz. This may result in per-client device type policy data that causes the AP to leave device type "a" on the 2.4GHz channel, thereby providing better connectivity for device type "a".
In a further aspect, by detecting client devices with low signal strength from their APs and aggregating such information across multiple networks, an average may be determined for a given client type. The average signal strength may be used to identify the client type so that the user may be provided with this information so that the user can take action and move the device closer to the AP. Poor placement of APs in a home or environment may also be detected. For example, if all or most of the wireless client devices associated with an AP have poor signal strength compared to the average signal strength of those particular client types in other AP networks, then the placement of a particular AP is designated as being poorly placed within its environment and a user notification is provided to the user to purchase another mesh device mesh AP device to support coverage.
In another aspect, the quality of the service scheduler at the AP is controlled when the network device detects current traffic types for various different client types and prioritizes time critical applications such as voice over IP (VoIP). For example, using operational information of video and non-video wireless clients, the network server generates per-client device type policy data, for example, indicating that there is a high likelihood of play time usage, or other operational information indicating a particular client as likely streaming video. The per-client device type policy data then informs the traffic scheduler at the AP for those devices to provide a particular airtime usage level to prioritize the client type device over other devices or within the network.
As another aspect, high mobility client devices have been determined to experience more channel variations and/or have more need to handoff to another AP within the network. The operational information is used to determine client types such as smart phones versus watches and non-mobile clients such as television monitors and workstations, whereby the operational information is used to estimate the mobility level of the client. Such information is used to cause the policy data to cause the AP to provide quality of service operations while providing intelligent handoff for those client types determined to be mobile versus non-mobile.
In other words, to generate the summarized data, the multi-AP device type
FIG. 6 illustrates an example of operational information-based policy data in accordance with aspects of the technology described herein. The per-client device type
The device type ID 610 in this example represents a non-mobile device such as a television monitor. In this example, the policy data indicates that the AP may monitor the operational information less frequently because the signal strength level and other operational information is less likely to change over time because the device type has been determined to be a non-mobile device. In this example, the device type has been determined to use a large amount of bandwidth through aggregation of bandwidth data of the device type across different networks. Thus, the per-client device
The AP-level policy data frame 602 also includes AP identification information 606 and AP policy data 612 on the AP level, as opposed to per-client device type level. In this example, the AP policy data 612 indicates that the AP should increase transmit power. For example, the per-client device type
As described above, the historical database policy uses operational information obtained over a desired period of time. In another example, historical operational data for each AP and per client device type is aggregated and evaluated to determine things such as total data transmitted via all APs by different device types within a given geographic region during a particular event such as a super bowl. Knowing the traffic pattern for the event in the previous year is used to manage the traffic pattern during the next superbowl of the future year, if desired, by per-client device type policy data provided to multiple APs for a particular device.
As noted above, operational information is collected at the per-AP and per-associated-client level aggregated over multiple different AP networks and is used to identify anomalies in client device and AP performance. Per-associated client tier information is based on per-client device type, such as whether the client device is a television, a printer, a particular smartphone (same manufacturer and different model or different manufacturer), a wearable device, a laptop, or any other suitable device that communicates with an access point. As a result, per-client device type policy data based on operational information from client devices of the same type in different networks is generated and provided to the appropriate AP, which then uses the per-client device type policy data to control the wireless client devices to improve operation of the wireless client devices and/or the AP network.
