An information handling system operating a diverse wireless location determination system, comprising receiving an instruction to determine a location of an endpoint information handling system having a plurality of network interface device modules supporting a plurality of wireless network protocols, a processor executing instructions to aggregate data including detected time of flight (TOF) signal distance and signal quality values relating to signals exchanged between the endpoint information handling system and a plurality of diverse wireless protocol access points, the processor to determine at least three diverse wireless protocol access point signals meet a signal quality threshold, where at least two of the diverse wireless protocol access points operate under different wireless protocols, and the processor conducting weighted multiangulation or multilateration utilizing the detected TOF signal distances of the exchanged signals based on the detected signal quality category and type of wireless protocol for the exchanged signal.

Methods, systems, and apparatus, including computer programs encoded on computer-storage media, for geofencing and location tracking for predicting and limiting disease exposure. In some implementations, location tracking data is received indicating locations of user devices over time. Location tags specifying visits of the user devices to different locations indicated by the location tracking data are defined. A geofence is assigned to each of the location tags to specify a geofenced area corresponding to the location tag. Disease transmission scores are assigned to first location tags representing visits of a first user. A disease exposure score is determined for a second user whose user device is determined, based on the location tracking data, to have entered at least one of the geofenced areas corresponding to the first location tags.

A system and method for identifying a customer's location at a business and provide notification to a company representative upon arrival of the customer at the business location. Real-time location determinations for the customer and customer location tracking can be provided. One or more wireless beacons communicate with the customer's electronic device. The beacons provide the system with real-time data about the customer's whereabouts, allowing for the confirmation and tracking of the customer at the location. A first non-limiting example of use, include a company that provides food and beverage allowing the customer to place an order for food and beverages on their electronic device and having the order delivered to the person at their current location as determined by the system. Another non-limiting example includes a company using the notification system to have assigned staff members notified of the customer's arrival.

A first signal generated from a signal generator may be synchronized with a local clock of a first device at a first time, and sent to a second device, the first signal having a first frequency. A second signal generated from the signal generator may be further synchronized with the local clock of the first device at a second time, the second signal having a second frequency different from the first frequency, and a difference between the second time and the first time being within a predetermined range of a predetermined time difference. The second signal may then be sent to the second device to enable the second device to determine a distance between the first device and the second device based at least in part on a phase difference between the first signal and the second signal.
