A newly filed patent (Publication Number: US20240040553A1) describes a system that includes a processor and memory storing executable instructions to facilitate operations. These operations involve selecting a frequency band for data communication between a communication device and network equipment based on the speed of the communication device. The system then instructs the communication device to use the selected frequency band for data communication. The patent further details scenarios where different frequency bands are selected based on varying speeds, with considerations for threshold speeds and service types associated with the data communication.

Additionally, the patent outlines operations where optimal frequency band profiles are determined through machine learning analysis of historical data communications. These profiles are then applied to schedule future data communications under different speeds. The patent also covers devices that receive scheduling information identifying frequency bands based on speed and use this information to perform data communication with network equipment. The frequency level of the selected band decreases with an increase in speed, and the device can send request information to indicate a preferred frequency band based on speed criteria. The patent also includes a non-transitory machine-readable medium with executable instructions for selecting frequency bands based on device speed and sending band data to the communication device for data communication purposes. Overall, the patent focuses on optimizing data communication performance by dynamically selecting frequency bands based on device speed and other relevant factors.
