Sacramento will be the first city in the country to get 5G cell service later this summer, but health concerns are now being raised about the equipment. 5G uses high frequency waves and is supposed to be 100 times faster than the current cell phone service. However, the 5G waves don't travel as far as current wireless frequencies so instead of large cell phone tower equipment spread far apart, the 5G requires small cell sites closer together. The FCC does set exposure limits for cell site antennas that transmit signals to phones. According to the National Cancer Institute, A limited number of studies have shown some evidence of statistical association of cell phone use and brain tumor risks." Firefighters in San Francisco have reported memory problems and confusion after the 5G equipment was installed outside of fire stations. The firefighters claim the symptoms stopped when they relocated to stations without equipment nearby. The City of Sacramento partnered with Verizon to offer 5G. Sacramento issued a statement to CBS13- reading in part: "The City currently has six 5G sites active. The City does not/cannot regulate wireless devices." Some cities, including Santa Rosa, have put their 5G plans on hold while health concerns are addressed.
