      Event Highlights Safe and Reliable Mobile Phone Technology Using CDMA on a 
      Commercial Aircraft
 FORT WORTH, Texas and SAN DIEGO —  July 15, 2004 —  QUALCOMM Incorporated 
      (Nasdaq: QCOM), pioneer and world leader of Code Division Multiple Access 
      (CDMA) digital wireless technology, and American Airlines, the world’s 
      largest carrier, today successfully demonstrated in-cabin voice 
      communications using commercially available CDMA mobile phones on a 
      commercial American Airlines aircraft. Through the use of an in-cabin 
      third-generation (3G) “picocell” network, passengers on the test flight 
      were able to place and receive calls as if they were on the ground.
 
 The proof-of-concept demonstration flight originated out of the 
      Dallas/Fort Worth International Airport. During the approximate two-hour 
      flight, passengers were able to place and receive phone calls and text 
      messages on their mobile phones. Passengers included members of the media 
      and government representatives.
 
 A small in-cabin CDMA cellular base station on the plane, that uses 
      standard cellular communications, was connected to the worldwide 
      terrestrial phone network by an air-to-ground Globalstar satellite link.
 
 The information gathered during this proof-of-concept demonstration flight 
      will be used to further research into the quality, convenience and safety 
      of communications with personal CDMA mobile phones carried by passengers 
      on a commercial aircraft.
 
 “We are pleased to have worked so closely with American Airlines to 
      complete this proof-of-concept demonstration for the in-flight use of 3G 
      CDMA technology,” said Dr. Irwin Jacobs, chairman and CEO of QUALCOMM. 
      “Together, we have anticipated the future needs of wireless subscribers in 
      the airline industry and are aggressively driving the delivery of 
      innovative solutions to meet those needs.”
 
 “Today, American Airlines and QUALCOMM showcased their strength as 
      technology pioneers and market leaders in their respective industries,” 
      said Dan Garton, executive vice president of marketing for American 
      Airlines. “American is committed to researching and providing innovative, 
      cutting-edge products and services that enhance our passengers’ traveling 
      experience and give our customers what they value. Even though commercial 
      availability of cell phone use in flight is approximately 24 months away, 
      American Airlines knows that our customers want to stay connected and this 
      proof-of-concept event is an important step in bringing in-cabin wireless 
      services to our customers.”
 
 As a leader in technology, American Airlines continues to explore 
      communication solutions that include broadband wireless connectivity and 
      cellular communication.

      phone solutions while continuing to work closely with the aviation
