Qualcomm Inc raised its fiscal 2011 revenue estimate to between $13.6 billion and $14.2 billion as sales of wireless chips accelerated.

It had previously forecast 2011 revenue of $12.4 billion and $13 billion.

Qualcomm said revenue rose to $3.35 billion in the December quarter, up 25 percent from the year-ago quarter. That was a bit above analysts' average estimate of $3.2 billion, according to Thomson Reuters I/B/E/S.
