METHOD FOR AVOIDING INTERFERENCE FROM A CELLULAR TRANSMITTER TO THE 2.4/5GHZ ISM BAND

摘要

A method, terminal, and computer program are disclosed to reduce radio interference in a wireless communications device having a combination of a wireless telephone unit, such as a GSM cellular phone, and a short range wireless communications unit, such as a WLAN communications unit or a Bluetooth communications unit. Bluetooth frequency hopping information and time domain operation information are input from the Bluetooth frequency hopping logic to the interference avoidance subsystem. GSM frequency hopping information and time domain operation information are input from the GSM frequency hopping logic to the interference avoidance subsystem. The interference avoidance subsystem compares a calculated interference probability with the required Bluetooth packet error rate limit for the current application and selectively sends a signal to the Bluetooth frequency hopping logic to change the Bluetooth frequencies.
