I would like to know why E-GPS supports GSM, not cdma?
What makes GSM better than cdma for this case?
Will 3G like WCDMA support E-GPS better than GSM?
Thank you.

Probably because GSM has won in the (worldwide) marketplace.

CDMA has one big advantage in that it supplies a us-level clock
reference automatically, but since it seems (from your other post) that
they have figured out how to do this over GSM as well, that advantage
doesn't seem to matter.
