Difference between Huawei BTS GSM and UMTS

Hi all,

I'm a telecommunications student, and preparing a project about 2G-3G evolution.

I need to know difference between Huawei BTS 3900 2G and 3G, is it about only software upgrade or is there any hardware extensions.

Thanks for your precious help.

Regards.
