Iran uses 'kill switch' to jam Starlink amid protests; Russia, China suspected of aid

• Iran is using a 'kill switch' approach to jam Starlink internet service to suppress communication during nationwide anti-government protests.
• The protests, driven by economic hardship and rising prices, have spread across all 31 provinces, with Iran initially cutting off cable and mobile internet.
• Military jammers are targeting Starlink, which protesters used as a 'Plan B' to bypass government controls, disrupting over 80% of traffic.
• Starlink's vulnerability to ground-level jamming stems from its reliance on GPS signals and wide-angle antennas, making it susceptible to signal interference.
• Experts suggest the jamming overpowers Starlink terminals; Russia or China are suspected of supplying the expensive jamming equipment.

Why It Matters: Iran is jamming Starlink internet during protests, likely with foreign aid, to control communication flow.
