We asked some experts about Asteroid 2005 YU 55 and whether it will have any impact on wireless service. The technical experts do not anticipate any significant disruptions from the close pass of YU55 this week.
When the earth crosses the tail of a comet or intercepts a group of small asteroids, they result is a meteor shower. These are fun to watch in the in the night time sky and are sometimes accompanied by some interference in the Very Low Frequency (VLF) bands. So far, these events have not created significant RF interference in the higher frequency bands used for wireless radio systems.
This week, we do have some significant (but unrelated) sunspot activity. Sunspots are associated with solar flares. When these flares are pointed at the earth they can cause some trouble, especially for satellite systems. The powerful ones, strong enough to affect terrestrial radio systems, are unpredictable and relatively rare events.
