Airborne Cell Phone Tests Project Achilles

Airfones

In 2001, GTE Airfone used the North American Telephony System (NATS) Terrestrial Radio System. There were 138 active base stations, each with a nominal 200-mile radius coverage.

From 1991 to 2006 some commercial airlines provided passengers with access to "seat-back" air-to-ground "Airfone" voice communications. On-board GTE radio transceivers linked to Airfone ground radio sites, which then interfaced with surface telephone carriers. The following digram shows where Airfone ground radio sites were located in the northeastern USA in 1991. Two typical coverage areas, with estimated radii of 128 miles, are represented by the red circles.


  • Dermal Deviations I'm all for asking questions about what really happened that day and who was responsible, but most calls were made at very low elevation through regular cellular towers.
  • Dan Plesse Which plane was "at very low elevation" and which cellular towers were used? Do you have there address? Locations? Thanks
Jason Lickness   "What happened to the people who bought tickets to be on those flights?" and you have never answered those questions.
Dan Plesse "What happened to the people who bought tickets to be on those flights?"

Well to find out more you have to trace the calls through the system to locate the source.
Tracing had to be done first to find out more about your question. Get the tracing done and YOU WILL HAVE YOUR ANSWER!!! and you will be a "truther" just like Jeffrey!!


airfone ground sites 1991

In 2003, Project Achilles researchers performed low altitude cell phone tests in private aircraft in the London, Ontario area of Canada. They found limited communications above 2,000 feet AGL (above ground level) and essentially no communications at 8000 feet AGL and above. The planes used in these tests had cruising speeds of 138 and 127 knots.


Here is a map of all RBS in 2006 (Source).



The list makes it possible to determine the time and RBS when the call was commenced as well as the time and RBS when it was disconnected.

I wonder what the average distance is between aircraft and (RBS) base station is and if that is still technically feasible.

 9/11 Commission paper on the GTE airfone calls. For a better view click  here.
Airfone is a terrestric system. The calling passenger is connected to the recipient via a net of ground stations (RBS=radio base station) scattered over the country. They connect the caller with the dialed number via landline. If the plane moves from one RBS area to the next, a handoff takes place, similar to cell calls. So in general, the position of a plane can be determined by the RBS with a decent uncertainty, just like VHF ACARS messages. Because the net of RBS is more wide-meshed than the net of ARINC RGS, the uncertainty is even bigger. Nevertheless, the list delivers valuable position information.

DOJ's Fake report might show where the calls were made and murders actually happened.  They say two cell towers was used to call parents, call centers, loved ones and Senator Ted Olson

Zero Cellular Tracing was done by any 9/11 Truth researcher and the 9/11 Truth Movement completely forgot. I am hear to remind researchers what has been missing, new videos, text messages whatever. Please find the location of cell towers and point them out on a map. 

Takedown (2000) "This film is based on the story of the capture of computer hacker "Kevin Mitnick". What method did they use? Cellular Tracing! Somehow everyone forgot, again!







  • Al Venden Ya , they didn't really think that whole cell phone thing through. You can ask any ham radio operator or pilot and they'll tell you it's impossible to connect to a cell tower from a flying aircraft. The main reason is the cell companies have developed special antennas that don't allow any signal to go up. They want their signal to reach as far out on the horizon as possible, any signal that goes up is considered waist.

    This came out shortly after 9/11 and there was an investigation and a hearing. Where under oath all were forced to admit there were no calls! They've all known the calls were phoney for a very long time now.


    "
    In the mid-1980s, when the first commercial cell phone networks began operating, the U.S. government adopted rules prohibiting their use onboard commercial flights. The rules were based on the above concerns.


    On Sept. 11, passengers disregarded those rules when they called loved ones and law enforcement officials using both Airfone-type and traditional cell phone technology. Another safety concern, however, is that terrorists might use the signal from a cell phone to detonate an onboard bomb."
