NEW YORK (Reuters) - Motorola Inc <MOT.N> is aiming to separate the company into two separate entities as soon as January, according to Greg Brown, its co-chief executive.

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.

The executive, who was speaking at the first Motorola Solutions investment conference, also said he expects the business to have an investment-grade rating at separation and vowed to consider dividend payments after the split.
