Satellite Radio: The Next Communications Revolution?
There are three general problems with
The target of satellite radio is a mobile platform
Foliage is similar to a blockage with a few
Spatial Diversity = Instead of having a single signal source, use multiple signal sources spread out
Frequency Diversity = Sending the same information on two separate and unrelated frequencies (preferably also spatially diverse)
Time Diversity = Delaying one of two spatially diverse signals in time before its broadcast
Repeater Stations are used in areas where even the combination of the other three solutions may not yield a “good” signal
