Are these ER (Extended Range) or EGSM (Enhanced GSM)?  As I
understand it, an EGSM cell "expands" the 900 MHz band slightly,
and requires an EGSM phone to take advantage of the extra traffic
capacity (but there's no increase in range).  ER (and EER) works
with any 900 MHz GSM phone.

Or are we just using our acronyms differently?

Into CDMA from what I can make out.  Optus seems to be making the
most significant GSM advances.
