Abstract: This paper analyzes USB protocol and wireless communication protocol, and introduces a protocol model on application layer aiming at the application of wireless 2.4 GHz USB device. This model realizes the communication between one slave and multi master. It improves the DSSS mechanism and independent communication channel mechanism to reduce noise and conflict during communication. An application example using Cypress CYRF6936 and Freescale MC68HC908JW32 MCU is realized.

Key words: 2.4 GHz wireless technique, Universal Serial Bus(USB), firmware
