why different standards for GSM FR - skakkeri2002 - Apr 23 13:05:00 2003



Hi All
Can any body give reasons (apart from homing sequence)for having
different ETSI standards such as Phase2, phase 2plus, 3GPP for same
GSM FR. The implementation standards and test vectors all seem to be
same.

Thanks in advance

K.S.
