SCHAUMBURG – Motorola Solutions Inc. said Wednesday that its fourth-quarter net income rose 83 percent, helped by stronger demand for its communications equipment from its government customers.

But its revenue outlook for the current quarter was below analysts' expectations sending shares lower late morning trading.

The company, which is based in Schaumburg, Ill., earned 336 million, or $1.18 per share, in the October-December period. That's up from $184 million, or 56 cents per share, in the same period a year earlier.
