LA building's lights interfere with cellular network, FCC says
That's not all ...
Many types of electronic equipment found in homes and offices emit electromagnetic radiation, and clashes with outside radio signals once were more common. For example, when cellular add-on cards for laptops first came out, emissions from the CPU sometimes kept the radios from working, Marshall said. In addition, there used to be laptops that put off enough radiation to interfere with onboard navigation systems on planes, said analyst Craig Mathias of Farpoint Group.
