This study assesses the various challenges facing the transition of LTE to LTE-Advanced, notably at the device baseband and RF levels. It extends the market segmentation of LTE mobile devices and related chips to reflect on the evolution of LTE across various paths, including FDD LTE, TDD LTE, multimode FDD-TDD LTE and network generations including LTE Classic and LTE-Advanced. The extended segmentation has been made to take into account the transformation in the mobile LTE market, notably the emergence of LTE Carrier Aggregation (LTE CA). The aim of this research is to evaluate the market potential for various multi-stream intra-band and inter-bands LTE CA combinations across all licensed LTE bands.
