is that a different case with the existing microcell? what kind of differences in rf emissions are there between the two? >> i am dane erickson, a registered professional engineer in the state of california. the antennas are directional in the vertical plane. even an antenna that is omnidirectional in the horizontal plane is still directional in the vertical plane. that means it radiates less energy directly downward. both patterns are taken into account, when we conduct our independent type galatians, whether a particular site complies with federal guidelines for human exposure to radio frequency energy. commissioner antonini: i guess my question was more that the older antenna is more omnidirectional then these are? >> that is correct. it would be on the directional in the horizontal plane, but directional in the vertical -- it would be omnidirectional in the horizontal plane, but directional in the vertical. the new antenna is directional in both the horizontal and vertical. the ready it much less energy directly below the antennas de
