Re 2. Are these various "slices of spectrum" (looks like 25 MHz wide for the various cellular choices, and 15 MHz for Globalstar satellite telephony) -- the place where the carriers have to "fit" their 1.25 MHz or 5 MHz channels ? Simple question, unfortunately, the US GOV is involved for the spectrum in the US. It does not look good. See the 3G doc at fcc.gov Worth a look, but somewhat big. Dated 15 Nov 2000. Home page at fcc.gov If you are very bored with nothing useful to do, then read on. Go here to pick your state and county svartifoss2.fcc.gov Some Examples, FL for state, dade for county, PCS Broad band, get choice of Cook Inlet, Anchorage, AK for the Miami-Ft. Lauderdale, FL market area or OMNIPOINT of Bellevue Wa for the Miami market area. Search is at gullfoss2.fcc.gov Select CL for the service, where CL = Cellular Telecommunications ATT CL is gullfoss2.fcc.gov Service codes are given at gullfoss2.fcc.gov Here for the GTE/ATT Antenna locations in Diamond H's back yard. svartifoss2.fcc.gov (soon to be TDMA?) and here for the Vodafone ones. svartifoss2.fcc.gov If you manage to "crack" search codes and find something useful, please fill me in on the details. Yep, it is boring, but better than counting dimpled chad with a magnifing glass on national TV ;-) Edit, some of these links seem to give a rather large download. Several Hundred Kbytes, not the faint of heart.

Ok Jon, here are the answers: 1. Is this "reverse" and "forward" terminology referring to the call coming from, or going to the cell tower (or low Earth orbit satellite) ? Forward link is from the base station to the handset. Reverse link is from handset to the base station. 2. Are these various "slices of spectrum" (looks like 25 MHz wide for the various cellular choices, and 15 MHz for Globalstar satellite telephony) -- the place where the carriers have to "fit" their 1.25 MHz or 5 MHz channels ? Yes. 3. If this is correct, and spectrum is obviously a limited and valuable resource, why would anyone EVER adopt W-CDMA technology, if it requires 5 MHz, instead of 1.25 MHz ? Good question!<gg> Later, MicroE

3. If this is correct, and spectrum is obviously a limited and valuable resource, why would anyone EVER adopt W-CDMA technology, if it requires 5 MHz, instead of 1.25 MHz ? Basically, all things being equal, one would be able to pack more information on a wider channel. For example fast internet access(384kbit/s) or videoconferencing(3G) require a wider radio frequency band. Of course, we know, that NTT, Nokia,and others developed this W-CDMA standards/technology to try to avoid Qualcomm patents(unsuccessfully). On the other hand, QCOM built on Cdma-One(IS-95) to tackle the higher data rates required by 3G.(1x,3x,...) some readable material on Wcdma fortunecity.com
