The difference could become quite a marketing tool - it would set REAL MEN and Cool Kids apart from the crowd. Provided it's not ugly and huge. The way technology is developing, with QUALCOMM's new radioOne for example, it might not be too many years before we are in that position. But terrestrial systems are zooming ahead with 3G and other cute services, such as precise 'where am I?' position location, so it will be a long time before Globalstar equals what's available with a terrestrial phone. But you can be sure that QUALCOMM understands that every Globalstar phone is a box for selling their many technologies. So they will be squeezing the dual-mode function into a seamless, convenient service with TOTAL coverage and high-quality. So Globalstar will in fact do EVERYTHING that a terrestrial phone does, but ALSO provides coverage to dream of. With Bluetooth, it would be simple to location an aerial by a window for convenient indoor use. This will all take time. Mqurice PS: RadioOne here:qualcomm.com ™, a revolutionary new technology for Code Division Multiple Access (CDMA) transceivers that uses Zero Intermediate Frequency (ZIF), or a direct conversion, architecture for the wireless handset market. Unlike traditional CDMA radios, which convert radio frequency (RF) signals to and from baseband in multiple steps — converting RF to or from intermediate frequency (IF), then converting IF to or from baseband — ZIF radios convert incoming RF signals directly to or from baseband analog signals. This direct conversion eliminates the need for large IF Surface Acoustic Wave (SAW) filters and additional IF circuitry, which significantly reduces the bill of materials (BOM), resulting in cost-effective multi-band and multi-mode handsets that can be produced in smaller form factors. "ZIF architecture has been the holy grail of many wireless communications standards," said Don Schrock, president of QUALCOMM CDMA Technologies. "By developing radioOne, QUALCOMM will help enable the rapid and cost-effective development of third-generation world phones capable of operating in multiple bands and modes." Until now, direct conversion for CDMA has been technically challenging because of the stringent interference specifications with which CDMA phones must comply. radioOne solves this problem by using new, advanced techniques developed by QUALCOMM CDMA Technologies (QCT) to enable high-dynamic-range receivers.
