When the problem of mobile phones first came to the fore I did some of the testing for the MHRA. I was talking to someone from the Home Office about how it is the pulsatile transmissions that seem to cause the most problems. He said that the new radio/phone system that was about to be introduced (I presume that this is Iridium). It worked on a packet system, sending out compressed bursts of speach data. A phone was not available for testing at the time. I do not know of any work that has been done with this system and medical devices. I would be very interested to know what they could do to a medical device.
The power of a transmitter is of significance. Phones needed to be close to a device to affect it, the porters radios (4watts) could have an effect at a range of several meters. Does anyone know the transmitting power of an Iridium handset?
