semiconductor chips. Sprint Nextel and WCA have proposed limits under Part 18 of FCC rules for ISM devices -- including microwave ovens, paint drying equipment and some medical imaging equipment -- to protect wireless broadband operators as they're moved from the 2150-2162 MHz band to the 2.5 GHz band as part of an FCC relocation plan. Axcelis told the FCC in Feb.: “If enacted, this proposal will have a negative impact on Axcelis, and more broadly, threatens to damage the utility of a wide variety of devices used only in manufacturing settings.” WCA said Axcelis is calling attention to a problem that doesn’t exist. “Of course, as even a cursory review of the record will reflect, no such proposal is pending before the Commission -- no one is suggesting that the Commission reduce the size of the ISM band at 2.4 GHz,” the Assn. said. “What is pending before the Commission is a proposal by WCA and others for imposing reasonable limits on emissions by ISM devices… Axcelis’s arguments simply are inapplicable to the interference… operations will suffer from the ISM devices that Axcelis does not sell.”
