<p>The present invention provides a method, an apparatus and a system for improving data transmission performance, relates to the field of communication technologies, and solves the problem of low data transmission performance caused by signal strength attenuation when a terminal transmits data by using a 5GHz WiFi network. Specific steps may include: determining whether a transmission rate for transmitting data is lower than a reference transmission rate that the data is actually required; if lower than the reference transmission rate, by querying part of or an entire working frequency band, obtaining a reference working frequency corresponding to a transmission rate that is higher than or equal to the reference transmission rate from the working frequency band; sending frequency modification indication information to a network access device; and modifying a working frequency for communication to the reference working frequency. The present invention can be applied to data transmission.</p> |
