The Concept Map you are trying to access has information related to:
Geosynchronous Satellite: Place in orbit that is exactly synchronized with rotation of the earth. Low Earth Orbit Satellite: Orbit a few hundred miles above the earth. The disadvantage of this type of satellite is that it rotate faster than the earth and cannot maintain contact with ground stations needed for the transfer of data. Low Orbit Satellite Arrays: Allows continuous communication with satellites in low orbit by launching a set of satellites so that each point on the ground has at least one satellite over head at any time. to Local Asychronous Communication, Copper wires: 1) Inexpensive and easy to install 2) Low resistance to electrical current To minimize interference: 1) Unshielded Twisted Pair (UTP) 2) Coaxial Cable 3) Shielded Twisted Pair (STP) here are more examples of different ways to transmit data Infrared: 1) Uses in appliances such as television and stereos. 2) Infrared is limited to small area like a single room., Copper wires: 1) Inexpensive and easy to install 2) Low resistance to electrical current To minimize interference: 1) Unshielded Twisted Pair (UTP) 2) Coaxial Cable 3) Shielded Twisted Pair (STP) here are more examples of different ways to transmit data Geosynchronous Satellite: Place in orbit that is exactly synchronized with rotation of the earth.
