Long-range frequency hopping spectrum

Abstract:

Methods and apparatuses for carrier selection are described. In one example, a method of carrier selection for a frequency-hopping wireless communication device includes using a fixed set of available carriers to hop over during communications. The method includes allocating a subset of the available carriers to a long-range carrier class. In one example, the subset of available carriers consists of at least two carrier clusters spaced widely in the frequency spectrum. The method further includes monitoring a transmit power level in the wireless communication device. The method further includes using the long-range carrier class to hop over during communications if the wireless communication device transmit power is greater than a predetermined level.
