Type an essay about "Transmission lines theory", explain with
it; transmission lines effects and their causes, then state the
difference between the propagation of electromagnetic waves in such
structures and the propagation in an unbounded space, like free

The transmission delay between two linked wireless devices is a
normal variable with a mean of 60 milliseconds and a standard
deviation of 5 milliseconds.

This question is to let you understand the impact of radio
channel condition on wireless transmission and to learn how
performance may be improved by re-transmitting small ACK
packets.
A satellite is orbiting the earth at the geostationary orbit. It
relays packets between two ground stations on the surface of the
earth. The distance between the satellite and the ground stations
is 72000 km. Ground station A sends a 1500 bytes packet to the
satellite and the satellite forwards it...
