Ericsson, the worlds top mobile telecom equipment maker, said on Thursday it would split its key Network unit in two as communications technology relies more on software and the Internet. Ericsson said it would create one separate business unit for mobile telecom equipment, called Radio, and one business unit called Cloud and IP. Networks chief Johan Wibergh would remain head of both units, Ericsson said. In a statement, Ericsson Chief Executive Hans Vestberg noted that whereas Ericsson had a clear number one position in mobile telecom equipment, such as radio base stations, it was still a challenger in cloud and IP (Internet Protocol) based communications.
