A few days ago, I got a little involved in a Usenet discussion about a contractor using his cell phone within a Telco CO while working on equipment repairs / upgrades. My position was that I didn't think this was a good idea, since I know that a cell phone will create about 5 to 10 V/M at about 2 meters distance.
The contractor made a statement that his cell phone had to be submitted to the "CO switching engineer", who, after doing some kind of measurements, allowed the use of the phone within the CO. I asked the contractor what kind of criteria the "switching engineer" used to evaluate the cell phone. The contractor replied (not very clearly) that the "switching engineer" used a "network analyzer with a plug-in S-parameter head." Well, I'm not sure if the contractor got the mushroom treatment, as that doesn't sound like what you need to evaluate RF field strength! But, what criteria should have been applied, and are there approved cell phones for such instances?
