Abstract

Dell has developed a method for evaluating the immunity of an electronic device (e.g., portable computer, personnel data assistant [PDA]1 etc) when placed in close proximity to electro-magnetic fields generated by wireless devices. In particular, wireless devices which operate in the global system for mobile communications (GSM) bands. For example, PC cards, cell phones, and cellular walkie talkies. The purpose of this study was to; 1) define an engineering test for evaluating a system's immunity to radiated fields generated by a wireless device and 2) develop a methodology for analyzing issues at the board level and identifying root cause.
