From NRUN65:

"9/11 revisited – The technology that existed in 2001 made it impossible for the cell phone calls from the nine passengers the FBI has records of having been made, to have been made from their hijacked jetliners in flight. This and the lack of background noise during the calls indicate that the calls were not made while in flight. If the cell calls were not made in flight then the Official 9/11 story is false.

FBI reports list several calls of varying duration from cell phones which were confirmed by caller ID of the recipients. However, in 2001, cell phones were useless in aircraft at high altitude and at high speeds because of the technology then in use. It wasn’t until 2004 that technology was being developed to enable fairly reliable cell phone calls from commercial jetliners. This combined with the clarity and lack of background noise of the received phone calls claimed to have been made from the planes in flight on 9/11 can’t help but cast serious doubt on the Official narrative.

Here is a 2004 Qualcomm Incorporated announced in a July 15, 2004 press release:
"American Airlines and Qualcomm Complete Test Flight to Evaluate In-Cabin Mobile Phone Use":
"Qualcomm Incorporated...and American Airlines today successfully demonstrated in-cabin voice communication using commercially available CDMA mobile phones on a commercial American Airlines aircraft...
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....'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 CDNA technology,' said Dr. Irwin Jacobs, chairman and CEO of Qualcomm…" [ ]

“Connections from the plane were generally good, although some calls were dropped. Sound quality was about the same as a regular cell call on the ground, other than the loud background noise on the MD-80 jet.” “There was a delay of about one second in the voice communications, like that encountered when using a satellite phone, which interfered with natural conversation. The delay was caused by the way voices are digitally transmitted in so-called packets from the airplane to the ground.”…

More on why cell phones would not have worked on 9/11:
"The Race To Allow Airborne Cell Phone Use" (Oct 1, 2004) - [ ]
"Several companies are racing toward a solution that combines satellite communications and onboard networks....from mid-2006, passengers should be able to begin using their own mobile phones for calls and text messaging. This service will be provided via the well-established Inmarsat constellation of geostationary satellites."

"How phones work in flight" - [ ]
" airplane would have to be no more than 10,000 feet in the air for any cell phones on board to still have a signal, according to Bill Rojas, director of telecom research at IDC Asia Pacific.
Speed can also make maintaining a cellular connection difficult, as a device has to switch from tower to tower to maintain a connection. Rojas told CNN that a plane would have to be going 155 miles per hour (250 kilometers per hour) or less for phones in cell-tower range to make or receive calls." "
