US mobile network operator Sprint Nextel has announced it is to transfer operation of its networks to Swedish telecommunications giant Ericsson. The seven-year, $5 billion agreement, said to be the largest network management deal ever made, will see 6,000 Sprint employees in the US transferred to a subsidiary owned by Ericsson in Overland Park, Kansas, in the third quarter of this year. Analysts have estimated that the network outsourcing and employee reshuffle could generate annual savings of $100 million for Sprint.
