We are not the only ones saying mobile broadband is the future. Nokia Siemens Networks, the equipment joint venture of Nokia and Siemens, said Wednesday that it planned to cut almost a quarter of its work force as it sought to bolster profit in a stagnating market for network gear. The company said it planned to eliminate 17,000 jobs by the end of 2013 in a wide-ranging austerity program to enable Nokia Siemens to refocus on mobile broadband equipment, the fastest-growing segment of the market. The reductions will slash the company’s work force by 23 percent from its current level of 74,000. Report.
