Abstract
A communication device partition for multiple device data standards to be received on one baseband integrated circuit is described. At least two interfaces are partitioned according to the data rate speed of various types of data standards and coupled to a multimode SDR modem. A digital baseband processor is coupled to the multimode SDR modem and receives the various types of application data compliant with various data standards.
