UNIVERSAL SERIAL BUS NETWORK INTERFACE CONTROLLER AND OPERATION MODE SWITCHING METHOD

摘要

A universal serial bus (USB) network interface controller and an operation mode switching method thereof are provided. The USB network interface controller determines an access point network band of a wireless network access point with which the USB network interface controller intends to connect, and switches from a first USB operation mode to a second USB operation mode to transmit data with a host so that an operation frequency of the USB network interface controller falls outside the access point network band. Afterwards, the USB network interface controller adjusts an operation network band to be the same as the access point network band, and exchanges information with the wireless network access point.

1. An operation mode switching method for use in a universal serial bus (USB) network interface controller, the USB network interface controller being connected with a host, the operation mode switching method comprising the following steps of:
searching a wireless network access point within a communication range; determining that the wireless network access point operates within an access point network band; switching a data transmission mode from a first USB operation mode to a second USB operation mode, and performing data transmission with the host in the second USB operation mode, wherein an operation frequency of the second USB operation mode falls outside the access point network band; adjusting an operation network band to the access point network band, and performing connection and data transmission with the wireless network access point within the operation network band.
