This makes me happy. I was hoping to see a worldwide shift towards LTE in the future. Sorry CDMA 1x, you're a dead format... GSM won.
GSM lost and CDMA won. Qualcomm got their CDMA patents into GSM, and decided to just license patents than worry about market share, and making products, and *gasp* competing.]]> http://www.dslreports.com/forum/Re-GSMCDMA-1x-21250590 Sat, 11 Oct 2008 11:16:45 EDT http://www.dslreports.com/forum/Re-GSMCDMA-1x-21248331 WCDMA / HSPA is a 'CDMA' based air interface which uses 5MHz physical channels, and ties into GSM's MAP core infrastructure (same infrastructure as GSM phones)

CDMA 1x is also a CDMA based air interface, but uses 1.25MHz physical channels and ties into ANSI core (i.e. same core as AMPS and TDMA used)
CDMA EVDO is a data only (IP based) air interface which uses 1.25MHz channels and ties into an IP backend.

Basically... UMTS/WCDMA (HSPA) and GSM utilize the same 'core' and SIM cards.

CDMA2000 (CDMA 1x/EVDO) utilize a different core.

LTE is an IP only based system which 'should' be able to bridge both CDMA EVDO and UMTS/WCDMA (HSPA) and even possibly WiMAX.

Don't get confused by the fact it uses a W-CDMA air interface as others have pointed.

Thats interesting cause HSPA is based on the CDMA wavelength. GSM carriers may be choosing HSPA as their upgrade paths, but HSPA is NOT GSM!!!!]]> http://www.dslreports.com/forum/Re-GSMCDMA-1x-21247568 Fri, 10 Oct 2008 17:31:19 EDT http://www.dslreports.com/forum/Re-GSMCDMA-1x-21247505 said by xenophon:

Well actually HSPA is not GSM, it's WCDMA.
Well HSPA is more like GSM than it is CDMA, the only thing it has in common with CDMA is the air interface.]]> http://www.dslreports.com/forum/Re-GSMCDMA-1x-21247505 Fri, 10 Oct 2008 17:19:29 EDT http://www.dslreports.com/forum/Re-GSMCDMA-1x-21247433 http://www.dslreports.com/forum/Re-GSMCDMA-1x-21247433 Fri, 10 Oct 2008 17:05:30 EDT http://www.dslreports.com/forum/Re-GSMCDMA-1x-21247272
I have to admit the acronyms are very confusing in these next steps of wireless evolution. ]]> http://www.dslreports.com/forum/Re-GSMCDMA-1x-21247272 Fri, 10 Oct 2008 16:36:48 EDT http://www.dslreports.com/forum/Re-GSMCDMA-1x-21247149 http://www.dslreports.com/forum/Re-GSMCDMA-1x-21247149 Fri, 10 Oct 2008 16:11:44 EDT http://www.dslreports.com/forum/GSMCDMA-1x-21246728 --
