NETGEAR has filed a patent for an unlicensed access point that can determine its location and identify licensed users in the 6 GHz band nearby. The access point generates a beacon frame to request location information from client devices, which then provide their location data. The access point uses this data to determine its own location and communicates with a central database containing information on registered licenses in the area. It then selects a communication channel within the 6 GHz band that doesn’t conflict with licensed users and provides Wi-Fi communication over that channel. The patent also includes a method for automatic frequency control by the access point. GlobalData’s report on NETGEAR gives a 360-degree view of the company including its patenting strategy.

A recently filed patent (Publication Number: US20230300884A1) describes a method for automatic frequency control by an access point. The method involves several steps to ensure efficient transmission of data to clients.

In the first step, the access point generates a data frame that includes a request for location information. The access point then receives location data from at least one client in response to the data frame. This location data is stored in memory for the access point.

The access point communicates with a remote server via an external network. The remote server stores a database that includes registered location information defining the location of licensed frequency bands. The access point receives available communication channels from the remote server that are not in use by the licensed frequency bands. It then selects one or more of these available communication channels for transmitting data to the clients.

The method also includes periodic communication between the access point and the remote server to detect changes in the registered location information. When new available communication channels are detected, the access point selects them for data transmission.

The first data frame generated by the access point is a beacon frame, and it periodically sets the location data for the access point. The method includes comparing the location data received from the clients at each periodic interval. If the difference between the present location and the location data received exceeds a predefined threshold, a new location is set for the access point. The access point then communicates with the remote server to obtain available communication channels at the new location and selects them for data transmission.

The method also covers scenarios where the first data frame is received by multiple clients. In this case, the location data for the access point is set to the average value of the location data received from each client.

The location data transmitted from the clients to the access point can include latitude, longitude, and altitude information. The clients can access a global positioning system to obtain their current location, or the location data can be obtained from data stored in memory, an application executing on the client, or an assigned IP address.

The first data frame can also include a request for authorization to access the location information from the clients. An application executing on the clients can determine the permission level before transmitting the location data to the access point. Encryption protocols can be established between the clients and the access point to secure the location data during transmission.

Overall, this patent describes a method for automatic frequency control that optimizes data transmission by selecting available communication channels based on location information obtained from clients.
