That comment makes me think of the interference possibility from different TX waveforms.
I am curious- has anyone seen correlation between levels or quantity of interference vs the two phone types: CDMA and GSM ? In a non-lab environment, the actual interference from GSM is orders of magnitude larger than CDMA. But what about in the lab environment? Best Regards, Patrick.

The signal path between the cell tower and the cell phone is so weak that the output from the cell phone is near max (my cell phone battery drains pretty quickly as a result) which makes it easier for the analyzer to pick it up. Better quality cables have helped, but I always turn off my cell phone when making radiated scans. I've never seen a problem with any other tests.

We routinely use cell phones while testing and they are good indication when something is broken. . - This message is from the IEEE Product Safety Engineering Society emc-pstc discussion list.
