Motorola has posted strong fourth quarter results, helped by a big increase in mobile handset sales.
The company recorded fourth-quarter sales of $6.5bn (£3.7bn) in mobile handset sales, which was 30% up on the same quarter last year.
The company said handset sales reached 44.7 million units in the quarter, which were 40% up year-on-year. Rival Sony Ericsson also recently reported strong fourth-quarter handset sales, for the vital period before Xmas.
Sales of operator network equipment fell in the quarter by 4% however, to $1.5bn, and operating profits slipped from $275m to $225m.
But in government and enterprise networking, sales were up 8% to $1.8bn, and operating profits jumped to $314m from $222m.
Motorola said total group sales for the full year were up 18% to $36.84bn, and operating profits jumped from $2.2bn to $4.6bn.
