Solar Radio Outbursts as Potential Radio Solar Radio Outbursts as Potential Radio Communications Jammers: Analysis of Selected Cases Communications Jammers: Analysis of Selected Cases

• Solar radio bursts can lowerthe SNR in wireless comms• Attention level is:• 1,000 SFU for mobiles• 40,000 SFU for GPSs• We analyzed 15 outburstsdetected by TSRS in 2000-03• 1,000 SFU was exceeded by• 80% 237 MHz events• 80% 327 MHz events• 67% 408 MHz events• 80% 610 MHz events• 53% 1420 MHz events• 53% 2695 MHz events• No event at 1420 MHz foundlarger than GPS threshold
