Talk:3G WCDMA
Finally after all this time somebody finally adds this. would suggest putting an example wav file, (,Or Ill try, in AMAmplitude Modulation, since this uses qam, and theres better harmonics, once I get my new RTL.) to the samples section. And putting a better description instead of the actual specifics.
Around my area in Michigan there are plenty of these in the 824-849, 869-894. They are also stronger, too.
And the frequency range 824-2,400 MHzMegaHertz (MHz) 10^6 Hz. Just to make this stand out a bit better. (Not to be mr admin)

Is this really CDMA2000? I thought that was the double 1.25 MHzMegaHertz (MHz) 10^6 Hz stuff and that the wide ~3.84 wide version was totally different.

WCDMA is European, which this is. I'm not sure about double 1.25MHz. I have a single 1.25 MHzMegaHertz (MHz) 10^6 Hz in the 800 band, thats US CDMACode Division Multiple Access. --Cartoonman (talk) 00:41, 22 September 2016 (NZST)
CDMA2000 is 2.5 MHzMegaHertz (MHz) 10^6 Hz. But if european, then it might be different. This page is definitely going to need inprovement. And Cartoonman, I have at least 3 samples of the regular 3G cdma2000 needing uploading, I got the newer SDR (THANK GOD), and are at least 50 secs in length, but once again, stupid API being a total craphole not letting me upload them to database. They might not sound familiar(with the temporal slots), but they are indeed 3g data, all at different frequencies in the 870-894 MHzMegaHertz (MHz) 10^6 Hz bands. If you have european 3G then they might be a bit wider, the regular US and South Korea 3G is double 1.25 Mhz. They should sound the same since they seem to use similar setups. CdmaOne is basically IS95, but that is only 2 Mhz in length. Ywsia1
I may have already contributed some of the narrow 3G you're talking about to the Unidentified section. So I guess this is a single WCDMA @ 3.84 Mchips, not a double signal? There are so many versions of CDMACode Division Multiple Access that I'm getting them confused. CDT2500
All I'm hearing in those sections aren't really anything but white noise. Shouldn't argue, but mine has better sound output on my 3 samples I am trying to provide. Where actual slots being processed. Also why would you want the narrow 1.25 Mhz 3g cdma2000 in unidentified? Merge possibly? And yes 3g can merge to envelop more devices on the same three networks. IS95 is CDMAOne and 2000 is the regular 3g. Ywsia1
I think I understand now. CDMA2000 is 3G for talk and text, and the wide 3.84 MHzMegaHertz (MHz) 10^6 Hz signal is 3G Internet? It would make sense because on some Verizon phones, Internet and phone calls use different protocols that are mutually exclusive. Also, it's cool that you were able to tell that no traffic was being carried on my samples. CDT2500
When slots are heard then theres traffic on the network... The signal just standsby with itself when no traffic is heard.... Kind of like an FMFrequency Modulation signal stands by for another transmission. Ywsia1
After more research I believe this to be 3G CDMACode Division Multiple Access Ev-DO. That means it only carries data and voice is handled on a different signal. And I think the title should be changed from WCDMA because this does not look like actual WCDMA, which is a GSM services. CDT2500
GSM doesn't employ CDMACode Division Multiple Access though? CDMACode Division Multiple Access based phones are not compatible with GSM services, and vice versa. --Cartoonman (talk) 14:24, 30 December 2016 (NZDT)
I am SO Glad they reformatted these pages in their 'correct' fashion. Ywsia1.
