“The year is off to a very strong start in part because we were able to recognize
revenue from some turnkey projects earlier than originally expected,” said Ira Palti, President
and CEO of Ceragon. “As wireless operators move forward with 4G/LTE plans in response to
accelerating growth in demand for data, they remain focused on flexible solutions that
accommodate the requirements of both current and future networks. As a result, the overall
business outlook continues to be positive and we remain confident in our target of 30-35%
revenue growth for the year, with profits growing at a higher rate than revenues.”
