Ericsson has announced that David Hammarwall is stepping up to head its networks business unit.

Hammarwall will replace Per Narvinger in the role, after he was named Ericsson's next CEO earlier this week.

The executive shake-up at the vendor is set to take place from October 1, when both Hammarwall and Narvinger start their respective new roles.
