Is it true that the latest OnStar modules are still CDMA-based? From what I've read, only the 9th generation OnStar hardware is RemoteLink capable, but it's still supposed to run over CDMA.
I'm wondering if this has to do with a partnership with Verizon? OnStar connects via Verizon in the US, and Bell Mobility in Canada. Bell (and their strategic partner Telus) has completed a massive country-wide transition from CDMA (1xRTT) to GSM (HSDPA) and all their new phones are GSM-based. There doesn't seem to be a large incentive for them to expand their existing CDMA network when they've actually been phasing out CDMA since 2009.
Due to the terrain in BC, highway cell coverage is quite spotty even on major routes, like Highway 3. There is an agreement in place with Telus (which has reciprocity with Bell) for a massive expansion of cellular coverage along major highways by 2016. I'm guessing they're not going to install any "legacy" CDMA hardware and this expansion will be GSM only. The expansion should cover over 1000 more miles of highway, but it'll do OnStar users a fat lot of good. Here's the actual agreement: http://www.cio.gov.bc.ca/local/cio/s...ships/cbca.pdf
Verizon seems to be the only large carrier holding out with CDMA. Virtually the rest of the world uses GSM. Maybe GM should contemplate GSM for OnStar Generation X...
