Eric, << No AMPS as far as I can tell >> Thanks for the Siemens link. Right after I posted (15 minutes had run out) I thought about the fact that AWS really has just about completed their migration to digital, even with key affiliates, so that makes sense. Many of Cingular's TDMA properties may be the same, but I have no visibility on that. Verizon's making good progress but they were the weakest link in that regard. The S47, targeted for availability in the fourth quarter of 2001, is the first phone to support two TDMA (Time Division Multiple Access) and two GSM (Global System for Mobile Communications) frequencies, giving both carriers and consumers unprecendented flexibility in where the phone can be used. It complements Siemens' S40 triple-band GSM phone that will be available in the United States beginning next month. ... The S47 will support TDMA 800 MHz and 1900 MHz frequencies as well as GSM 900MHz and 1900 MHz, making it the first global phone of its type. That answers several questions and particularly the GSM-800 one. I figured the GSM-900 one because of the international roaming requisite. That phone might not do everything but it goes a looooooooooooooooooong way towards solving the woes of the IS-136 guys and is key to their migration. I have always thought that a 1xRTT air interface was the best way to solve Cingular's needs, given their kind of patchy footprint ... 800 MHz here, 1900 MHz there (unlike AWS who has lots of both everywhere. Missing link is the CDMA GAIT phone equivalent. You sure don't slap one of them together overnight. GAIT phones have been about as delayed as anything I've ever seen. There supposedly were prototypes out last July, but the TDMA SIM standard was still soft, and was hanging things. I recall several comments out of UWCC and GERAN last year (Cingular and AWS originated) about how multi-mode chips did NOT solve interoperability issues. I suspect that is part of what caused the AWS flip and I am really betting Cingular will flip same way. Focusre. LOL! Good to see you checking in. We'd like to see more of you, here and on G&K. Best, - Eric -
