Object: Study how to update the SCDMA networks and suit TD-SCDMA. Methods: To comprehension evolve SCDMA networks gradually and build TD-SCDMA networks. Results: It can transfer to the TD-SCDMA smoothly by analyzing upgrade ability from SCDMA itself progress. It updates existing 2.5G SCDMA MAN to 3G TD-SCDMA easily by software updated based on IP core and needs less investment. Conclusion: It realizes to return together from the diversity for SCDMA, TD-SCDMA and WiMAX-like McWiLL as consanguinity and kernel technologies during 2.5G, 3G and B3G evolvement. That is bottom- up gradually from homologous tech. and its ready-made networks, marketization and less investment relatively mode.
