Ericsson is set to upgrade 3 Italia's 3G access as part of an extended deal between the two firms, it has been announced.
The contract extension has been arranged in a bid to boost the Italian operator's efforts to cope with mobile data traffic growth.
The deal will also see 3 Italia's core and transport network upgraded to support 4G services.
It has been suggested that customers will be able to get faster speeds in more places once the work is completed.
By the end of this month, the operator will be the only firm in Italy to offer up to 42 Mbps of downlink coverage and up to 5.76 Mpbs of uplink across its nationwide network.
Vincenzo Novari, 3 Italia's chief executive officer, said: "Thanks to our continued successful co-operation with Ericsson, we will remain a reference for innovation and network development in the Italian market."
