Patient monitors and equipment that administers drugs in controlled doses are vital pieces of equipment which must work correctly at all times, or the patient might be in danger. Tests have shown that these pieces of equipment can be affected by the radio waves given out by mobile phones. You can hear a 'phone interfering with electronic hardware when you put a mobile 'phone near a hifi or TV - when the 'phone rings or gets a text message, the audio circuits in the hifi or TV pick up the radio waves and a buzzing can be heard through the speakers. Same idea in the hospital, except that rather than a harmless buzz the radio waves could cause the equipment to give false readings, or put too much or too little drugs into the patient. However, the likelihood of problems ocurring is slight as all vital electronic equipment is supposed to be protected against interference, so not using mobile 'phones in hospitals is a "better safe than sorry" rule.

I think you are talking about the Spectralink phones that are wireless mobile/cellular phones which are used in hospitals. There have been studies done that state that mobile/cell phones do not interfere with hospital equipment. "In a study published in the March issue of Mayo Clinic Proceedings, researchers say tests showed normal use of cell phones caused no noticeable interference with patient care equipment. Two cell phones were involved in the study, using different technologies from different carriers, and 192 medical devices. Three hundred tests were performed over a five-month period in 2006, without a single problem incurred." (Cell Phones safe to use in Hospitals, Study Says March 10, 2007) = =
