Understand that the real problem with the mobile phones (back when they were bricks) was that at altitude they would communicate with about 10 cells at once and throw every else off the system.
Also understand there could be problems with transmitters but laptops, gameboys and portable playstations - has me beat.
Also I have on one occasion used a mobile phone (about 20 n.miles south of Dubbo in NSW) to contact the responsible person who was holding my SARTIME details that due weather we were running late and I expected to be on the ground and able to cancel SAR in 20 minutes - including time to taxi and tie down.
Is there are hard eveidence of interference with systems? Has anyone been able to replicate erroneous readings by triggering with transmissions from phones or other devices?
