Ericsson has announced that it is to deploy a new cellular network for Telecom Italia Mobile (TIM) which will offer download speeds of up to 20Mbps and peak upload speeds of 5.8Mbps. Trials of the new system will begin shortly, with the initial network rollout taking place in Milan in June, ahead of a national expansion in the second half of the year. The HSPA deployment will include Multiple Input and Multiple Output (MIMO), a technology that uses two or more antenna branches to transmit data to a consumer, making it possible to provide higher data rates to each user and improve the spectrum efficiency in the radio network.
