I guess my first question is you are a EE student and not an amateur
radio operator?
At any rate
802.11b, depending on the data rate, is probably direct sequence
spread spectrum..a good explanation of the differences can be
found in the ARRL Handbook for Radio Communications...

That would be nice.

so ho
so how would Spread spectrum play out internationally.
Currently the usa is 72mhz
most of europe I think is 35
So would that also unite us to one solution? :-)

glitch free operation while eliminating the possibility of being shot

I believe this will be the norm in the next few
years. It will take a while for everyone to make the transition. I'm still
concerned about the range, so I'll wait for some of you to put a $1500 moldy a
half a mile down range and see if it still works. Is it the spread spectrum that

Keep in mind that the 2.4ghz. freq. does not propagate well/(at all) through

Well great. Spread spectrum is sounding mighty cool.
Problem. When I bought my radio 5 years ago I bought a transmitter I will
never out grow. It's working great and I love the thing! It's doing all I
want and has room to spare!
So, yes. Everyone should buy a Spread Spectrum radio. It's super

They have done field testing and it appears they are confident in its
performance. They are a bit ambiguous about the range, as noted here,
but if you read between the lines it appears to be around 2000 feet.
On RC groups Terry N. indicates 1500 feet.
