Polkomtel implements NSN LTE voice solution

21 Mar 2013

Polish cellco Polkomtel, which offers services under the Plus brand, has implemented Nokia Siemens Networks’ (NSN’s) Circuit Switched FallBack (CSFB) solution for providing voice serviced alongside Long Term Evolution (LTE). CFSB allows LTE subscribers to switch to Polkomtel’s 3G network to make and receive voice calls. Dietmar Heinrichs, head of Polkomtel customer team at NSN noted that ‘[NSN’s] CFSB solution reused existing network investments in Polkomtel’s radio and core networks, saving capital costs for the operator. In addition, CSFB can easily be upgraded to support voice-over-LTE (VoLTE).’
