NEW YORK, Nov 13 (Reuters) - Qualcomm Inc (QCOM.O), seeking to cut costs in the face of slowing demand for cell phones, has stopped developing a next-generation wireless technology called Ultra Mobile Broadband.

The wireless chip maker will put its resources into a rival high-speed technology called Long Term Evolution, which some of its major customers, such as Verizon Wireless, have backed, said Qualcomm Chief Executive Paul Jacobs.

Jacobs told an annual analysts' meeting on Thursday that there are no plans to undertake "a large layoff across the company" as he expects a modest market recovery in cell phone chip demand the second half of 2009.

Qualcomm issued weaker-than-expected full-year forecasts last week, leading some investors to question how sure it could be of its outlook in the difficult economic environment.

"We're trying to do as good a job as we can predicting the market. With that said there's still some uncertainty out there," Jacobs said, citing challenges in predicting phone volume sales and product mixes for 2009.

Jacobs said he was still seeing growing demand for advanced cell phones, putting Qualcomm in a good position as it sells technology licenses as well as chips.

"We're looking at difficult times in the near term, but the long-term strength of the company is strong," he said.

Qualcomm expects customers to tighten inventory levels to support 14 weeks of sales in the first half of fiscal year 2009, down from 19 weeks in September.

Jacobs said that device manufacturers were much more cautious than carriers, which appeared "somewhat cautious." On the sidelines of the conference, he said operators would likely cut spending on network equipment before devices.

"I would expect if they make a trade off, the trade off would be more around capital spending than handsets," he said.
