UMTS networks can be operated with GSM/GPRS networks. Systems use different frequency bands, so BTSs and mobiles will (should) not interfere with each other. Some vendors claim their core network (MSC/HLR/SGSN ect) and BSC/RNC are UMTS compatible, but most operators will prefer to build a totally separate/independent UMTS network. Some of the latest GSM BTSs can also have UMTS radio parts and share the same rack.
