Motorola Plans January 4 Separation

Motorola plans to split on January 4, the company said.

Motorola Mobility stock, which represents Motorola’s cellphone and television set-top box business, will trade under the ticker symbol MMI on the New York Stock Exchange.

The remaining company, which is changing its name to Motorola Solutions, will comprise Motorola’s public safety and enterprise business.

The company had previously said it would separate the company in the first quarter into two parts: Motorola Mobility, which will sell mobile handsets and television set-top boxes, and Motorola Solutions, which will supply wireless technology to governments and enterprises.

Brown, who will head Motorola Solutions, said that he expects that business to grow in a range of 4 percent to 5 percent in 2011 and set a long-term growth target of 5 percent to 8 percent.
