re: Qualcomm Claims GSM1x Trial Looking for a few discussion/talking points from operator side guys... with strategic planning experience..etc...

GSM1X... how does that fit in from a RF planning perspective... can an operator afford such a deployment? Even with the potential advantages that 1X brings on the data/ip side? vs. gprs...

What bands would the operator need to be? 1900MHz? or they would own a bunch of cross band licenses...

need to understand some of the planning motivations/considerations...

From a vendor perspective, Qualcomm's got a GSM1X site forming gradually over time...
http://www.qualcomm.com/GSM1x/...

Handsets and infrastructure... will be interesting to see who wants to tackle this stuff for real...

Similarly... GSM850MHz has somewhat same/different connotations... RF planning not req'd. but a new set of handsets...

What if someone in their crazy mindset wanted to do.. GSM850MHz1X?

cheers,
M.

Why bother? At 850 MHz the only networks around are running ANSI41 cores and so there is no advantage (I don't see any advantage for networks with GSM MAP + GPRS cores either but that's another story...)

P.S. Imagine the poor guy who tries to propose this in either 3GPP or 3GPP2 (and as far as I can see you would need new specifications coming from both bodies)

re: Qualcomm Claims GSM1x Trial Some may claim that there are potential benefits in letting your roamers go abroad... or rather your subscribers...

If you deployed CDMA... i guess you could take advantage of GSM 1X phones... CDMA on the home network, and your users can still roam using GSM elsewhere...?

re: Qualcomm Claims GSM1x Trial Is it just me or is this really a long shot?

Why not do EDGE? Would installation of 1X on GSM have any impact on the existing warranties on those boxes? You really only need that extra capacity in the urban areas anyway where the cells are small enough to provide solid EDGE coverage.

I like the idea that carriers have another choice to GPRS/EDGE or W-CDMA because that will speed up the GSM/UMTS club but is gsm 1x really realistic?

I am afraid not. Dualmode cdma/gsm1x phones will not work in GSM networks since both only "do" cdma. To roam onto a GSM network you will need a real GSM mode (GSM radio plus GSM signalling).

re: Qualcomm Claims GSM1x Trial IMHO, I think you missed the point when you talk about "warranties". The issue is a "little bit bigger than that".

This GSM1X idea is about installing a completely new radio and core network (based on cdma2000 plus a full blown MSC that they call a "MSN"). That means new antenna, new racks at cell site, new controllers, new transmission gear, new interfaces to test in the core not to mention the small problem of new standards (but that, as my handle suggests, is the fun part)
