Abstract
A method for avoiding signal interference between a first RF device and a second RF device is provided. The first and second RF devices are co-located and the first RF device is configured to operate within a semi-stationary range of a frequency band. The second RF device is configured to operate by changing channels within the frequency band. The method initiates with a communication interface being provided between the first RF device and the second RF device. Then, the second RF device receives the semi-stationary range and a mode for the first RF device through the communication interface. Next, the second RF device is adapted to avoid the semi-stationary range of the frequency band of the first RF device when the mode of the first RF device is in an active mode. An apparatus where two RF devices are co-located without causing interference for each other is also provided.
