Is WCDMA IMT-2000 the same as IMT-2100 ?

Hello there!

My "GiONEE Pioneer P2M" when enter to Engineer Mode gives me the following bands: GSM (GSM850, EGSM900, DCS1800, PCS1900) and UMTS (WCDMA-IMT-2000, WCDMA-PCS-1900, WCDMA-GSM-900)

But instead of WCDMA-IMT-2000 it's mentioned: WCDMA-IMT-2100 on websites ? are they the same ? will it cause a carrier registration issue ?
