RE
: Senate Bill 701 (Wahab): Signal jammers – REQUEST FOR SIGNATURE Dear
Governor Newsom,
The
City of Sunnyvale requests you sign SB 701 into law . This bill would criminalize the manufacturing, importing, marketing, purchasing, selling, or operation of signal jammers. Radio frequency jammers disrupt critical communications systems used by drones and first responders, as well as satellite navigation and landing systems relied upon by aircraft. Despite a federal ban, these devices remain readily available for purchase online on various commercial platforms.
Bay
Area cities have seen a rise in signal jammer used to interfere with emergency communications or facilitate crimes such as theft. This issue extends beyond the Bay Area, with malicious use of jammers reported nationwide.
Mul
tiple incidents across the United States have demonstrated the severe risks of signal jammers, including canceled flights and compromised airline landings. Notable cases include a runway shutdown in Texas and GPS interference affecting aircraft 40 miles from Dallas-Fort Worth. While aviation industries work to strengthen systems against jamming and spoofing, SB 701 is critical to prohibit the sale and use of signal jammers, protecting California’s airports and residents from potential harm.
Thi
s bill aligns with the City of Sunnyvale’s General Plan, Chapter 6 – Goal SN-7, Policy SN-7.1. For these reasons, we support SB 701. For these reasons, we support SB 701 and request that it be signed into law . Please do not hesitate to contact me or Daniel Pistor , Director of Public Safety, at [email protected] if you have any questions.
