bux "There is a common misconception that Qualcomm has offered a 3G solution that is not a suitable upgrade for GSM operators. Do you think Qualcomm is not keenly aware that most of the wireless world are GSM? I have even seen it suggested that the 3.8Mhz or 4.0Mhz chip rates are somehow backwards compatible with GSM but Qualcomms 3.6Mhz rate and/or 3G CDMA proposals are not! Hogwash! GSM has no chip rate to be compatible with. Any of the 3G air interfaces can be interfaced with packet-based network infrastructure." i never read anywhere that a GSM network could not be converted to a CDMA2000 operation. the conversion of GSM to WCDMA, however, is proposed to be less costly by Nokia for two reasons, (a) Nokia has developed the base station WCDMA product which can be bi or tri modal, and (b) known shared technology is greater between a GSM to WCDMA conversion than other forms. according to Nokia site, cells are not in need of substantial reconfiguring; WCDMA uses same antenna, site support, same NMS tools (media solutions - internet/media software solutions and standards currently proposed and in use in GSM are the same for WCDMA), and similar transmission technologies. WCDMA also utilizes TDD functions which are provided for in the platform of current GSM networks. "The fully compliant Nokia UltraSite Base Station family is a true multistandard, multimedia solution, including various combinations of WCDMA, EDGE and GSM to suit every network configuration. For existing mobile operators, this means significant savings when upgrading to WCDMA by sharing transmission, site support, antennas, NMS tools and existing sites." nokia.com
